The '''National Popular Vote Interstate Compact''' ('''NPVIC''') <!-- NOT "NaPoVoInterCo"! --> is an agreement among a group of [[U.S. state]]s and the [[District of Columbia]] to award all their [[United States Electoral College|electoral votes]] to whichever [[United States presidential election|presidential ticket]] wins the overall [[Popular vote (representative democracy)|popular vote]] in the 50 states and the District of Columbia. The [[Interstate compact|compact]] is designed to ensure that the candidate who receives the most votes nationwide is elected [[President of the United States|president]], and it would come into effect only when it would guarantee that outcome.<ref name=NPVICHQ>{{cite web |title=National Popular Vote |url=https://www.nationalpopularvote.com/ |access-date=22 July 2024}}</ref><ref>{{cite web|title=National Popular Vote|url=http://www.ncsl.org/research/elections-and-campaigns/national-popular-vote.aspx|website=National Conference of State Legislatures|publisher=NCSL|access-date=November 9, 2015|date=March 11, 2015|archive-date=December 17, 2015|archive-url=https://web.archive.org/web/20151217002135/http://www.ncsl.org/research/elections-and-campaigns/national-popular-vote.aspx|url-status=live}}</ref><ref name="CtEC">{{cite journal|last1=Brody|first1=Michael|title=Circumventing the Electoral College: Why the National Popular Vote Interstate Compact Survives Constitutional Scrutiny Under the Compact Clause|journal=Legislation and Policy Brief|date=February 17, 2013|volume=5|issue=1|pages=33, 35|url=http://digitalcommons.wcl.american.edu/cgi/viewcontent.cgi?article=1043&context=lpb|access-date=September 11, 2014|publisher=Washington College of Law Journals & Law Reviews at Digital Commons @ American University Washington College of Law|archive-date=March 27, 2015|archive-url=https://web.archive.org/web/20150327020529/http://digitalcommons.wcl.american.edu/cgi/viewcontent.cgi?article=1043&context=lpb|url-status=live}}</ref> 

Introduced in 2006, {{lcfirst:{{#section:National Popular Vote Interstate Compact|As_of_month}}}}, it was joined by {{#invoke:NPVIC status|states|passed|spell}} states and the District of Columbia. They have {{#invoke:NPVIC status|EVs|passed}} electoral votes, which is {{#invoke:NPVIC status|percent|passed|538|0}} of the [[United States Electoral College|Electoral College]] and {{#invoke:NPVIC status|percent|passed|270|0}} of the 270 votes needed to give the compact [[coming into force|legal force]]. The idea gained traction amongst scholars after [[George W. Bush]] won the presidential election but lost the popular vote in [[2000 United States presidential election|2000]], the first time the winner of the presidency had lost the popular vote since [[1888 United States presidential election|1888]].

Certain legal questions may affect implementation of the compact. Some legal observers believe states have [[plenary power]] to appoint electors as prescribed by the compact; others believe that the compact will require congressional consent under the [[Constitution of the United States|Constitution]]'s [[Article One of the United States Constitution#Clause 3: Compact Clause|Compact Clause]] or that the presidential election process cannot be altered except by a [[Article Five of the United States Constitution|constitutional amendment]].

==Mechanism==
Taking the form of an [[interstate compact]], the agreement would [[Coming into force|go into effect]] among participating states only after they collectively represent an absolute majority of votes (currently at least 270) in the Electoral College. Once in effect, in each presidential election the participating states would award all of their electoral votes to the candidate with the largest national popular vote total across the 50 states and the District of Columbia. As a result, that candidate would win the presidency by securing a majority of votes in the Electoral College. Until the compact's conditions are met, all states award electoral votes in their current manner.

The compact would modify the way participating states implement [[Article Two of the United States Constitution#Clause 2: Method of choosing electors|Article II, Section 1, Clause 2]] of the [[U.S. Constitution]], which requires each [[State legislature (United States)|state legislature]] to define a method to appoint its electors to vote in the Electoral College. The Constitution does not mandate any particular legislative scheme for selecting electors, and instead vests state legislatures with the [[plenary power|exclusive power]] to choose how to allocate their states' electors (although systems that violate the 14th Amendment, which mandates equal protection of the law and prohibits racial discrimination, are prohibited).<ref name=CtEC/><ref>[[McPherson v. Blacker]] {{ussc|146|1|1892}}</ref> States have chosen various methods of allocation over the years, with regular changes in the nation's early decades. Today, all but two states (Maine and Nebraska) award all their electoral votes to the single candidate with the [[first-past-the-post|most votes]] statewide (the so-called "[[Plurality voting|winner-take-all]]" system).{{NoteTag|Maine and Nebraska currently award one electoral vote to the winner in each congressional district and their remaining two electoral votes to the statewide winner. In addition, because Maine uses [[Instant-runoff voting|ranked choice voting]] in its presidential elections, its certified popular vote count will be from the final result of a series of instant runoffs that continue until only two presidential slates remain.<ref name=me2024/>}}

The compact would no longer be in effect should the total number of electoral votes held by the participating states fall below the threshold required, which could occur due to withdrawal of one or more states, changes due to the decennial [[United States congressional apportionment|congressional re-apportionment]], or an increase in the size of [[United States Congress|Congress]], for example by admittance of a [[51st state]]. The compact mandates a July 20 deadline in presidential election years, six months before [[Inauguration Day]], to determine whether the agreement is in effect for that particular election. Any withdrawal by a state after that deadline will not be considered effective by other participating states until the next president is confirmed.<ref name=BillText/>

==Motivation==
{{See also|United States Electoral College#Impacts and reception|United States presidential elections in which the winner lost the popular vote}}

Reasons given for the compact include:

# State winner-take-all laws encourage candidates to focus disproportionately on a limited set of [[swing states]], as small changes in the popular vote in those states produce large changes in the electoral college vote.{{pb}}For example, in the 2016 election, a shift of 2,736 votes (or less than 0.4% of all votes cast) toward Donald Trump in New Hampshire would have produced a four electoral vote gain for his campaign. A similar shift in any other state would have produced no change in the electoral vote, thus encouraging the campaign to focus on New Hampshire above other states. A study by [[FairVote]] reported that the 2004 candidates devoted three-quarters of their peak season campaign resources to just five states, while the other 45 states received very little attention. The report also stated that 18 states received no candidate visits and no TV [[campaign advertising|advertising]].<ref>{{cite web |url=http://www.fairvote.org/presidential/?page=1677 |archive-url=https://web.archive.org/web/20060602104422/http://www.fairvote.org/presidential/?page=1677 |url-status=dead |archive-date=June 2, 2006 |title=Who Picks the President? |publisher=FairVote |access-date=June 11, 2008 }}</ref> This means that swing state issues receive more attention, while issues important to other states are largely ignored.<ref name=NYEd>{{cite news |url=https://www.nytimes.com/2006/03/14/opinion/14tue1.html |title=Drop Out of the College |work=The New York Times |date=March 14, 2006 |access-date=June 11, 2008 |archive-date=June 15, 2015 |archive-url=https://web.archive.org/web/20150615063648/http://www.nytimes.com/2006/03/14/opinion/14tue1.html |url-status=live }}</ref><ref>{{cite news |url=http://www.denverpost.com/opinion/ci_5628615 |title=Electoral College is outdated |work=Denver Post |date=April 9, 2007 |access-date=June 11, 2008 |archive-date=January 8, 2008 |archive-url=https://web.archive.org/web/20080108224626/http://www.denverpost.com/opinion/ci_5628615 |url-status=live }}</ref><ref name=HillKee>{{cite journal |title=The Electoral College, Mobilization, and Turnout in the 2000 Presidential Election |last1=Hill |first1=David |last2=McKee |first2=Seth C. |journal=American Politics Research |volume=33 |issue=5 |date=September 2005 |pages=700–725 |doi=10.1177/1532673X04271902 |s2cid=154991830 }}</ref>

Whether these splits suggest an advantage for one major party or the other in the Electoral College is discussed in {{section link||Suggested partisan advantage}} below.

==Enactment prospects==
{{see also|#Adoption|#Constitutionality}}
[[Political analyst]] [[Nate Silver]] noted in 2014 that all jurisdictions that had adopted the compact at that time were [[Red states and blue states|blue states]], and that there were not enough electoral votes from the remaining blue states to achieve the required majority. He concluded that, as [[swing state]]s were unlikely to support a compact that reduces their influence (see [[#SWING|§ Campaign focus on swing states]]), the compact could not succeed without adoption by some red states as well.<ref name=538comment>{{cite news|last1=Silver|first1=Nate|author-link1=Nate Silver|title=Why a Plan to Circumvent the Electoral College Is Probably Doomed|url=https://fivethirtyeight.com/features/why-a-plan-to-circumvent-the-electoral-college-is-probably-doomed/|website=[[FiveThirtyEight]]|publisher=[[ESPN]]|access-date=17 July 2014|date=17 April 2014|archive-date=October 30, 2014|archive-url=https://web.archive.org/web/20141030182653/http://fivethirtyeight.com/datalab/why-a-plan-to-circumvent-the-electoral-college-is-probably-doomed/|url-status=live}}</ref> [[Republican Party (United States)|Republican]]-led [[Bicameralism|chambers]] have adopted the measure in New York (2011),<ref name=NY_hist>{{cite web |url=https://www.nationalpopularvote.com/state/ny |title=New York |publisher=National Popular Vote |date=January 19, 2016 |access-date=August 7, 2018 |archive-date=August 8, 2018 |archive-url=https://web.archive.org/web/20180808011310/https://www.nationalpopularvote.com/state/ny |url-status=live }}</ref> [[Oklahoma]] (2014), and [[Arizona]] (2016), and the measure has been unanimously approved by Republican-led committees in [[Georgia (U.S. state)|Georgia]] and [[Missouri]], prior to the [[2016 United States Presidential Election|2016 election]].<ref name="NPV_main">{{cite web |title=National Popular Vote! |url=https://www.nationalpopularvote.com |publisher=National Popular Vote |date=December 17, 2015 |access-date=August 7, 2018 |archive-date=August 8, 2018 |archive-url=https://web.archive.org/web/20180808014626/https://www.nationalpopularvote.com/ |url-status=live }}</ref> On March 15, 2019, Colorado became the most [[Red states and blue states|"purple" state]] to join the compact, though no Republican legislators supported the bill and Colorado had a state [[government trifecta]] under Democrats.<ref name="Rakich">{{cite news |last1=Rakich |first1=Nathaniel |title=The Movement To Skip The Electoral College Is About To Pass A Major Milestone |url=https://fivethirtyeight.com/features/the-movement-to-skip-the-electoral-college-just-passed-a-major-milestone/ |access-date=18 March 2019 |work=FiveThirtyEight |date=March 5, 2019 |archive-date=March 8, 2019 |archive-url=https://web.archive.org/web/20190308001437/https://fivethirtyeight.com/features/the-movement-to-skip-the-electoral-college-just-passed-a-major-milestone/ |url-status=live }}</ref> It was later submitted to a [[2020 Colorado Proposition 113|ballot initiative]], where it was approved by 52% of voters.

===Protective function of the Electoral College===
Certain [[Founding Fathers of the United States|founders]], notably [[Alexander Hamilton]] and [[James Madison]], conceived of the Electoral College as a deliberative body which would weigh the inputs of the states, but not be bound by them, in selecting the president, and would therefore serve to protect the country from the election of a person who is unfit to be president.{{sfn|Rossiter|2003|p=410}}<ref>{{Cite book |url=https://founders.archives.gov/documents/Madison/01-10-02-0178 |title=The Federalist |volume=10 |date=22 November 1787 |via=National Archives |access-date=August 6, 2024}}</ref> However, the Electoral College has never served such a role in practice. From 1796 onward, presidential electors have acted as "rubber stamps" for their parties' nominees. Journalist and commentator [[Peter Beinart]] has cited the election of Donald Trump, whom some, he notes, view as unfit, as evidence that the Electoral College does not perform a protective function.<ref>{{Cite web|url=https://www.theatlantic.com/politics/archive/2016/11/the-electoral-college-was-meant-to-stop-men-like-trump-from-being-president/508310/|title=The Electoral College Was Meant to Stop Men Like Trump From Being President|first=Peter|last=Beinart|author-link=Peter Beinart|date=November 21, 2016|website=The Atlantic|access-date=July 7, 2020|archive-date=July 7, 2020|archive-url=https://web.archive.org/web/20200707210454/https://www.theatlantic.com/politics/archive/2016/11/the-electoral-college-was-meant-to-stop-men-like-trump-from-being-president/508310/|url-status=live}}</ref> {{As of|2025}}, no election outcome has been determined by an elector deviating from the will of their state.<ref name="NPV-buffer">{{cite web |title=Myth: The Electoral College acts as a buffer against popular passions |date=January 19, 2019 |url=https://www.nationalpopularvote.com/section_9.17#myth_9.17.2 |publisher=National Popular Vote |access-date=7 November 2019 |archive-date=May 18, 2020 |archive-url=https://web.archive.org/web/20200518225016/https://www.nationalpopularvote.com/section_9.17#myth_9.17.2 |url-status=live }}</ref> Furthermore, thirty-two states and the District of Columbia have laws to prevent such "[[faithless elector]]s",<ref>{{cite web |title=Faithless Elector State Laws |url=https://www.fairvote.org/faithless_elector_state_laws |website=Fair Vote |access-date=4 March 2020 |archive-date=December 19, 2016 |archive-url=https://web.archive.org/web/20161219162610/https://www.fairvote.org/faithless_elector_state_laws |url-status=live }}</ref><ref>{{cite web |title=Laws Binding Electors |url=http://presidentialelectorlaws.us |access-date=4 March 2020 |archive-date=January 14, 2021 |archive-url=https://web.archive.org/web/20210114193449/https://presidentialelectorlaws.us/ |url-status=live }}</ref> and such laws were upheld as constitutional by the [[Supreme Court of the United States|Supreme Court]] in 2020 in ''[[Chiafalo v.

Under the current system, campaign focus – as measured by spending, visits, and attention to regional or state issues – is largely limited to the few [[swing states]] whose electoral outcomes are competitive, with politically "solid" states mostly ignored by the campaigns. The adjacent maps illustrate the amount spent on advertising and the number of visits to each state, relative to population, by the two major-party candidates in the last stretch of the [[2004 United States presidential election|2004 presidential campaign]]. Supporters of the compact contend that a national popular vote would encourage candidates to campaign with equal effort for votes in competitive and non-competitive states alike.<ref>{{cite web|url=http://www.fairvote.org/what-is-the-national-popular-vote-plan|title=National Popular Vote|work=FairVote|access-date=July 20, 2010|archive-date=October 4, 2012|archive-url=http://webarchive.loc.gov/all/20121004144613/http://www.fairvote.org/what-is-the-national-popular-vote-plan|url-status=live}}</ref> Critics of the compact argue that candidates would have less incentive to focus on regions with smaller populations or fewer urban areas, and would thus be less motivated to address rural issues.<ref name=Pont/><ref name=NPVmemo>{{cite web |url=http://archive.nationalpopularvote.com/resources/7-Page-NPV-Memo-V33-2007-6-1.pdf |title=Agreement Among the States to Elect the President by Nationwide Popular Vote |date=June 1, 2007 |access-date=July 13, 2008 |publisher=National Popular Vote |archive-date=May 6, 2019 |archive-url=https://web.archive.org/web/20190506013147/http://archive.nationalpopularvote.com/resources/7-Page-NPV-Memo-V33-2007-6-1.pdf |url-status=live }}</ref>

===Disputed results and electoral fraud===

Opponents of the compact have raised concerns about the handling of close or disputed outcomes. National Popular Vote contends that an election being decided based on a disputed tally is far ''less'' likely under the NPVIC, which creates one large nationwide pool of voters, than under the current system, in which the national winner may be determined by an extremely small margin in any one of the fifty-one smaller statewide tallies.<ref name=NPVmemo/> However, the national popular vote can theoretically be closer than the vote tally within any one state. In the event of an exact tie in the nationwide tally, NPVIC member states will award their electors to the winner of the popular vote in their state.<ref name=BillText>{{cite web |url= http://www.nationalpopularvote.com/bill-text |title= Text of the National Popular Vote Compact Bill |publisher= National Popular Vote |date= May 5, 2019 |access-date= May 6, 2019 |archive-date= May 6, 2019 |archive-url= https://web.archive.org/web/20190506013153/https://www.nationalpopularvote.com/bill-text |url-status= live }}</ref> Under the NPVIC, each state will continue to handle disputes and statewide [[election recount|recounts]] as governed by their own laws.<ref>{{cite web|url=http://www.fairvote.org/recounts|title=Statewide Election Recounts, 2000–2009|work=FairVote|access-date=May 3, 2012|archive-date=April 3, 2012|archive-url=https://web.archive.org/web/20120403144709/http://www.fairvote.org/recounts|url-status=live}}</ref> The NPVIC does not include any provision for a nationwide recount, though Congress has the authority to create such a provision.<ref name="national_recount">{{cite web |url=https://www.nationalpopularvote.com/section_9.15#myth_9.15.7 |title=Myth: There is no mechanism for conducting a national recount |publisher=National Popular Vote |date=January 20, 2019 |access-date=April 5, 2019 |archive-date=April 21, 2019 |archive-url=https://web.archive.org/web/20190421122936/https://www.nationalpopularvote.com/section_9.15#myth_9.15.7 |url-status=live }}</ref>

Pete du Pont argues that the NPVIC would enable [[electoral fraud]], stating, "Mr. [[Al Gore|Gore]]'s 540,000-vote margin [in [[2000 United States presidential election|the 2000 election]]] amounted to 3.1 votes in each of the country's 175,000 precincts. 'Finding' three votes per precinct in urban areas is not a difficult thing...".<ref name=Pont/> However, National Popular Vote counters that altering the outcome via fraud would be more difficult under a national popular vote than under the current system, due to the greater number of total votes that would likely need to be changed: currently, a close election may be determined by the outcome in one (see [[tipping-point state]]) or more close states, and the margin in the closest of those states is likely to be far smaller than the nationwide margin, due to the smaller pool of voters at the state level, and the fact that several states may be capable of tipping the election.<ref name=NPVmemo/>

A statistical analysis by ''[[FiveThirtyEight]]''{{'}}s [[Nate Silver]] of all presidential elections from 1864 to 2016 (see adjacent chart) found that the Electoral College has not consistently favored one major party or the other, and that any advantage in the Electoral College does not tend to last long, noting that "there's almost no correlation between which party has the Electoral College advantage in one election and which has it four years later."<ref name="Silver-EC-advantage">{{cite news |last1=Silver |first1=Nate |title=Will The Electoral College Doom The Democrats Again? |url=https://fivethirtyeight.com/features/will-the-electoral-college-doom-the-democrats-again/ |access-date=3 April 2019 |work=[[FiveThirtyEight]] |date=November 14, 2016 |archive-date=April 3, 2019 |archive-url=https://web.archive.org/web/20190403174523/https://fivethirtyeight.com/features/will-the-electoral-college-doom-the-democrats-again/ |url-status=live }}</ref> In all four elections since 1876 in which [[United States presidential elections in which the winner lost the popular vote|the winner lost the popular vote]], the Republican became president; however, Silver's analysis shows that such splits are about equally likely to favor either major party.<ref name="Silver-EC-advantage"/> A popular vote-Electoral College split favoring the Democrat [[John Kerry]] nearly occurred in [[2004 United States presidential election|2004]].<ref name="LAT-Kerry">{{cite news |title=California should join the popular vote parade |url=https://www.latimes.com/opinion/la-xpm-2011-jul-16-la-ed-vote-20110716-story.html |access-date=6 June 2019 |work=[[Los Angeles Times]] |date=July 16, 2011 |archive-date=May 18, 2020 |archive-url=https://web.archive.org/web/20200518102922/https://www.latimes.com/opinion/la-xpm-2011-jul-16-la-ed-vote-20110716-story.html |url-status=live }}</ref>

===State power relative to population===

[[File:US 2020 Census State Population Per Electoral Vote.png|thumb|right|upright=2|State population per electoral vote from the 2020 census]]

There is some debate over whether the Electoral College favors small- or large-population states. Those who argue that the College favors low-population states point out that such states have proportionally more electoral votes relative to their populations.{{NoteTag|Each state's electoral votes are equal to the sum of its seats in both houses of Congress. The allocation of House seats, which is nominally proportional to population (see [[United States congressional apportionment#Apportionment methods|United States congressional apportionment § Apportionment methods]]), has been distorted by the [[Reapportionment Act of 1929|fixed size of the House since 1929]] and the requirement that each state have at least one representative. Each state has two Senate seats regardless of population. Both factors favor less populous states.<ref name=Hono/>}}<ref name=Hono>{{cite news |url=http://archives.starbulletin.com/2007/04/29/editorial/editorial02.html |title=Electoral College should be maintained |work=Honolulu Star-Bulletin |access-date=June 12, 2008 |date=April 29, 2007 |archive-date=October 5, 2011 |archive-url=https://web.archive.org/web/20111005064516/http://archives.starbulletin.com/2007/04/29/editorial/editorial02.html |url-status=live }}</ref><ref>{{cite interview |url=https://www.pbs.org/newshour/bb/election/july-dec00/bbo_11-6.html |archive-url=https://web.archive.org/web/20080112114406/https://www.pbs.org/newshour/bb/election/july-dec00/bbo_11-6.html |archive-date=January 12, 2008 |url-status=dead |first1=David |last1=Broder |first2=David |last2=Brooks |first3=Tom |last3=Oliphant |interviewer=Margaret Warner |work=PBS NewsHour |title=Campaign Countdown |date=November 6, 2000 |access-date=June 12, 2008}}</ref> {{As of|2020}}, this results in voters in the least-populous state – Wyoming, with three electors – having 220% greater voting power than they would under purely proportional representation, while voters in the most populous state, California, have 16% less power.{{NoteTag|Per the [[2020 United States census#State rankings|2020 census]], Wyoming accounted for 0.17% of the US population, but it controls 0.56% of the Electoral College.

Others, however, believe that since most states award electoral votes on a winner-takes-all system (the "unit rule"), the potential of populous states to shift greater numbers of electoral votes gives them more clout than would be expected from their electoral vote count alone.<ref>{{cite news |url=http://www.slate.com/id/1006680 |work=Slate |title=Faithless Elector Watch: Gimme 'Equal Protection' |first=Timothy |last=Noah |date=December 13, 2000 |access-date=June 12, 2008 |archive-date=March 8, 2008 |archive-url=https://web.archive.org/web/20080308061454/http://www.slate.com/id/1006680/ |url-status=live }}</ref><ref>{{cite book |url=http://yalepress.yale.edu/yupbooks/book.asp?isbn=0300080360 |archive-url=https://web.archive.org/web/20110606185249/http://yalepress.yale.edu/yupbooks/book.asp?isbn=0300080360 |archive-date=2011-06-06|first1=Lawrence D. |last1=Longley |last2=Peirce |first2=Neal |title=Electoral College Primer 2000 |publisher=Yale University Press |year=1999}}</ref><ref>{{cite book|url=http://www.oup.com/us/catalog/general/subject/Law/ConstitutionalLaw/?view=usa&ci=9780195307511 |first=Sanford |last=Levinson |title=Our Undemocratic Constitution |publisher=Oxford University Press |year=2006 |url-status=dead |archive-url=https://web.archive.org/web/20080328222321/http://www.oup.com/us/catalog/general/subject/Law/ConstitutionalLaw/?view=usa |archive-date=March 28, 2008 }}</ref>

Some opponents of a national popular vote contend that the non-proportionality of the Electoral College is a fundamental component of the federal system established by the Constitutional Convention. Specifically, the [[Connecticut Compromise]] established a [[bicameral legislature]] – with proportional representation of the states in the House of Representatives and equal representation of the states in the Senate – as a compromise between less populous states fearful of having their interests dominated and voices drowned out by larger states,<ref>{{cite web |title=Debates in the Federal Convention of 1787 – July 5 |work=Teaching American History |url=https://teachingamericanhistory.org/resources/convention/debates/0705-2/ |access-date=9 February 2020 |archive-date=May 19, 2020 |archive-url=https://web.archive.org/web/20200519004230/https://teachingamericanhistory.org/resources/convention/debates/0705-2/ |url-status=dead }}</ref> and larger states which viewed anything other than proportional representation as an affront to principles of democratic representation.<ref>{{cite web |title=Debates in the Federal Convention of 1787 – July 9 |work=Teaching American History |url=https://teachingamericanhistory.org/resources/convention/debates/0709-2/ |access-date=9 February 2020 |archive-date=May 17, 2020 |archive-url=https://web.archive.org/web/20200517212837/https://teachingamericanhistory.org/resources/convention/debates/0709-2/ |url-status=dead }}</ref> The ratio of the populations of the most and least populous states is far greater currently (68.50 {{As of|2020|4|1|alt=as of the [[2020 United States census|2020 census]]}}) than when the Connecticut Compromise was adopted (7.35 as of the [[1790 United States census|1790 census]]), exaggerating the non-proportional component of the compromise allocation.{{Synthesis inline|date=December 2024}}

===Irrelevance of state-level majorities===
Three governors who have vetoed NPVIC legislation—[[Arnold Schwarzenegger]] of California, [[Linda Lingle]] of Hawaii, and [[Steve Sisolak]] of Nevada—objected to the compact on the grounds that it could require their states' electoral votes to be awarded to a candidate who did not win a majority in their state. (California and Hawaii have since enacted laws joining the compact.) Supporters of the compact counter that under a national popular vote system, state-level majorities are irrelevant; in all states, votes contribute to the nationwide tally, which determines the winner. Individual votes combine to directly determine the outcome, while the intermediary measure of state-level majorities is rendered obsolete.<ref name="CA SB 37"/><ref>{{cite news |url=http://archives.starbulletin.com/2007/04/24/news/briefs.html |work= [[Honolulu Star-Bulletin]] |title=State stays with electoral system |date=April 24, 2007 |access-date=July 13, 2008 |archive-date=October 5, 2011 |archive-url=https://web.archive.org/web/20111005064523/http://archives.starbulletin.com/2007/04/24/news/briefs.html |url-status=live }}</ref><ref>{{cite news |title=What's Wrong With the Popular Vote? |url=http://www.hawaiireporter.com/story.aspx?6ddf1e11-986b-4a18-ab2d-dac2925fbcaa |work=Hawaii Reporter |date=April 11, 2007 |access-date=July 13, 2008 |archive-url = https://web.archive.org/web/20080110014711/http://www.hawaiireporter.com/story.aspx?6ddf1e11-986b-4a18-ab2d-dac2925fbcaa |archive-date = January 10, 2008}}</ref>

Some opponents of the compact contend that it would lead to a proliferation of third-party candidates, such that an election could be won with a plurality of as little as 15% of the vote.<ref name="NPV_9.7.3">{{cite web |title=9.7.3 MYTH: A national popular vote will result in a proliferation of candidates, Presidents being elected with as little as 15% of the vote, and a breakdown of the two-party system. |url=https://www.nationalpopularvote.com/section_9.7#_ftn3.244 |website=National Popular Vote |date=January 19, 2019 |access-date=23 July 2020 |archive-date=July 23, 2020 |archive-url=https://web.archive.org/web/20200723173243/https://www.nationalpopularvote.com/section_9.7#_ftn3.244 |url-status=live }}</ref><ref name="FNP">{{cite news |last1=Morningstar |first1=Bernard L. |title=Abolishing Electoral College is a bad idea |url=https://www.fredericknewspost.com/opinion/letter_to_editor/abolishing-electoral-college-is-a-bad-idea/article_bcea47b7-c1e0-59b4-81cc-c0bf802929e9.html |access-date=23 July 2020 |work=[[Frederick News-Post]] |date=Sep 7, 2019 |archive-date=August 4, 2020 |archive-url=https://web.archive.org/web/20200804052637/https://www.fredericknewspost.com/opinion/letter_to_editor/abolishing-electoral-college-is-a-bad-idea/article_bcea47b7-c1e0-59b4-81cc-c0bf802929e9.html |url-status=live }}</ref> However, evidence from U.S. gubernatorial and other plurality-based races does not bear out this suggestion.

===State voting law differences===
Each state sets its own rules for voting, including [[voter registration|registration]] deadlines, [[Voter identification laws|voter ID laws]], poll opening and closing times, conditions for [[Early voting|early]] and [[Absentee ballot|absentee voting]], and [[Felony disenfranchisement in the United States|disenfranchisement of felons]].<ref name=USAFacts>{{cite web |url= https://usafacts.org/articles/how-do-voting-laws-differ-by-state/ |title=How do voting laws differ by state? |website= USA Facts |date= August 22, 2022 |access-date= December 26, 2022 |archive-date= December 25, 2022 |archive-url= https://web.archive.org/web/20221225162957/https://usafacts.org/articles/how-do-voting-laws-differ-by-state/ |url-status= live }}</ref> Currently, parties in power have an incentive to create state rules meant to skew the ''relative'' turnout for each party in their favor, by, for example, making voting more difficult for groups that tend to vote against them. Under NPVIC, this incentive may be reduced, as electoral votes will no longer be rewarded on the basis of statewide vote totals, but on nationwide results, which are less likely to be significantly affected by the voting rules of any one state. Under the compact, however, there may be an incentive for states to create rules that make voting easier for all, to increase their ''total'' turnout, and thus their impact on the nationwide vote totals. In either system, the voting rules of each state have the potential to affect the election outcome for the entire country.<ref name="NPV-state-voting-laws">{{cite web |title=Myths about Logistical Nightmares Arising from Differences in State Laws |url=https://www.nationalpopularvote.com/section_9.9 |website=National Popular Vote |date=January 19, 2019 |publisher=[[National Popular Vote Inc.]] |access-date=12 June 2023}}</ref>

==Constitutionality==
{{main|Constitutionality of the National Popular Vote Interstate Compact}}
There is ongoing legal debate about the [[Constitutional law of the United States|constitutionality]] of the NPVIC. At issue are interpretations of the [[Article One of the United States Constitution#Clause 3: Compact Clause|Compact Clause of Article I, Section X]], and states' [[plenary power]] under the [[Article Two of the United States Constitution#Clause 2: Method of choosing electors|Elections Clause of Article II, Section I]].

===Compact clause===
A 2019 report by the [[Congressional Research Service]] examined whether the NPVIC should be considered an [[interstate compact]], and as such, whether it would require congressional approval to take effect. At issue is whether the NPVIC would affect the [[Federalism#Division of powers|vertical balance of power]] between the federal government and state governments,{{refn|group=list|name=Virginia v.

With respect to vertical balance of power, the NPVIC removes the possibility of [[contingent election]]s for President conducted by the [[U.S. House of Representatives]]. Whether this would be a ''[[de minimis]]'' diminishment of federal power is unresolved. The Supreme Court has also held that congressional consent is required for interstate compacts that alter the horizontal balance of power among the states.<ref name="Florida v 1855"/><ref name="ReferenceA"/> There is debate over whether the NPVIC affects the power of non-compacting states with regard to presidential elections.<ref name="Hendricks">{{cite journal|journal=[[Election Law Journal]]|first=Jennifer S.|last=Hendricks|volume=7|number=3|ssrn=1030385|title=Popular Election of the President: Using or Abusing the Electoral College?|date=July 1, 2008|pages=218–236|doi=10.1089/elj.2008.7306}}</ref><ref name="Turflinger">{{cite journal|first=Bradley T.|last=Turflinger|title=Fifty Republics and the National Popular Vote: How the Guarantee Clause Should Protect States Striving for Equal Protection in Presidential Elections|url=http://scholar.valpo.edu/cgi/viewcontent.cgi?article=1443&context=vulr|journal=Valparaiso University Law Review|publisher=Valco Scholar|access-date=September 25, 2012|year=2011|volume=45|issue=3|pages=795; 798; 833–843|archive-date=October 6, 2014|archive-url=https://web.archive.org/web/20141006180449/http://scholar.valpo.edu/cgi/viewcontent.cgi?article=1443&context=vulr|url-status=live}}</ref><ref name="Schleifer">{{cite journal|last=Schleifer|first=Adam|year=2007|title=Interstate Agreement for Electoral Reform|journal=Akron Law Review|volume=40|issue=4|pages=717–749|url=https://ideaexchange.uakron.edu/cgi/viewcontent.cgi?article=1221&context=akronlawreview|access-date=April 17, 2019|archive-date=May 18, 2020|archive-url=https://web.archive.org/web/20200518053612/https://ideaexchange.uakron.edu/cgi/viewcontent.cgi?article=1221&context=akronlawreview|url-status=live}}</ref><ref name="Muller 2007">{{cite journal|last=Muller|first=Derek T.|title=The Compact Clause and the National Popular Vote Interstate Compact|journal=[[Election Law Journal]]|volume=6|issue=4|pages=372–393|publisher=Mary Ann Liebert, Inc.|doi=10.1089/elj.2007.6403|date=November 2007|s2cid=53380514}}</ref><ref name="Muller 2008">{{cite journal|last=Muller|first=Derek T.|title=More Thoughts on the Compact Clause and the National Popular Vote: A Response to Professor Hendricks|journal=[[Election Law Journal]]|volume=7|issue=3|pages=227–233|publisher=Mary Ann Liebert, Inc.|date=2008|ssrn=2033853|doi=10.1089/elj.2008.7307}}</ref><ref>{{cite journal|last=Drake|first=Ian J.|date=September 20, 2013|title=Federal Roadblocks: The Constitution and the National Popular Vote Interstate Compact|journal=[[Publius (journal)|Publius: The Journal of Federalism]]|publisher=[[Oxford University Press]]|volume=44|issue=4|pages=690–691|doi=10.1093/publius/pjt037}}</ref>

Republican support for replacing the Electoral College with a national popular vote dropped significantly, from 54% in 2011 to 19% in 2016, which Gallup attributed to a partisan response to the 2016 result, where the Republican candidate [[Donald Trump]] won the Electoral College despite losing the popular vote.<ref>{{cite web|first=Art|last=Swift|title=Americans' Support for Electoral College Rises Sharply|publisher=[[Gallup (company)|Gallup]]|url=https://news.gallup.com/poll/198917/americans-support-electoral-college-rises-sharply.aspx|access-date=April 5, 2019|date=December 2, 2016|archive-date=April 1, 2019|archive-url=https://web.archive.org/web/20190401063357/https://news.gallup.com/poll/198917/americans-support-electoral-college-rises-sharply.aspx|url-status=live}}</ref> In March 2018, a [[Pew Research Center]] poll showed that 55% of Americans supported replacing the Electoral College with a national popular vote, with 41% opposed, but that a partisan divide remained in that support, as 75% of self-identified Democrats supported replacing the Electoral College with a national popular vote, while only 32% of self-identified Republicans did.<ref>{{cite web|title=5.

Since the 1940s, when modern scientific polling on the subject began, a majority of Americans have preferred changing the electoral college system.{{sfn|Keyssar|2020|p=5}}<ref name="Laurent" /> Between 1948 and 1979, Congress debated electoral college reform extensively, and hundreds of reform proposals were introduced in the House and Senate. During this period, Senate and House Judiciary Committees held hearings on 17 different occasions. Proposals were debated five times in the Senate and twice in the House, and approved by two-thirds majorities twice in the Senate and once in the House, but never at the same time.{{sfnm|1a1=Keyssar|1y=2020|1pp=120-176|2a1=Neale|2a2=Nolan|2y=2019|2p=4}} In the late 1960s and 1970s, over 65% of voters supported amending the Constitution to replace the Electoral College with a national popular vote,{{sfn|Keyssar|2020|p=5}} with support peaking at 80% in 1968, after [[Richard Nixon]] almost lost the popular vote while winning the Electoral College vote.<ref name="Laurent" /> A similar situation occurred again with [[Jimmy Carter]]'s election in 1976; a poll taken weeks after the election found 73% support for eliminating the Electoral College by amendment.<ref name="Laurent" /> Carter himself proposed a Constitutional amendment that would include the abolition of the electoral college shortly after taking office in 1977.<ref>{{cite web|url=https://www.nytimes.com/1977/03/23/archives/carter-proposes-end-of-electoral-college-in-presidential-votes.html|title=Carter Proposes End of Electoral College in Presidential Votes|work=New York Times|author=Warren Weaver Jr. |date=March 23, 1977|access-date=July 15, 2022}}</ref> After a direct popular election amendment failed to pass the Senate in 1979 and prominent congressional advocates retired or were defeated in elections, electoral college reform subsided from public attention and the number of reform proposals in Congress dwindled.{{sfnm|1a1=Keyssar|1y=2020|1pp=178-207|2a1=Neale|2a2=Nolan|2y=2019|2p=4}}

===Interstate compact plan===
[[File:ElectoralCollege2028.svg|thumb|upright=1.5|Distribution of electoral votes following the [[2020 United States census|2020 census]]]]

The 2000 US presidential election produced the first divergence between the national popular and electoral votes since 1888, as [[Al Gore]] carried the popular vote but lost the Electoral College vote to [[George W. Bush]].{{sfn|Neale|Nolan|2019|p=5}} This sparked studies and proposals from scholars and activists on electoral college reform, ultimately leading to the National Popular Vote Interstate Compact (NPVIC).{{sfn|Neale|Nolan|2019|pp=5-7}}

In 2001, two articles were published by law professors suggesting paths to a national popular vote through state legislative action rather than constitutional amendment.{{sfn|Keyssar|2020|p=195}} The first, a paper by [[Northwestern University]] law professor [[Robert W. Bennett]], suggested states could pressure Congress to pass a constitutional amendment by acting together to pledge their electoral votes to the winner of the national popular vote.<ref name="Bennett">{{cite journal|journal=[[The Green Bag (1997)|The Green Bag]]|first=Robert W.|last=Bennett|author-link=Robert W.

A few months later, [[Yale Law School]] professor [[Akhil Amar]] and his brother, [[University of California, Hastings College of the Law|University of California Hastings School of Law]] professor [[Vikram Amar]], wrote a paper suggesting states could coordinate their efforts by passing uniform legislation under the [[Article Two of the United States Constitution#Clause 2: Method of choosing electors|Presidential Electors Clause]] and [[Compact Clause]] of the Constitution.<ref name=amar2001>{{cite web |url=https://supreme.findlaw.com/legal-commentary/how-to-achieve-direct-national-election-of-the-president-without-amending-the-constitution.html |title=How to Achieve Direct National Election of the President Without Amending the Constitution: Part Three Of A Three-part Series On The 2000 Election And The Electoral College |work=[[Findlaw]] |first1=Akhil Reed |last1=Amar |author-link1=Akhil Amar |first2=Vikram David |last2=Amar |author-link2=Vikram Amar |date=December 28, 2001 |access-date=November 25, 2020 |archive-date=December 3, 2020 |archive-url=https://web.archive.org/web/20201203204145/https://supreme.findlaw.com/legal-commentary/how-to-achieve-direct-national-election-of-the-president-without-amending-the-constitution.html |url-status=live }}</ref> The legislation could be structured to [[trigger law|take effect]] only once enough states to control a majority of the Electoral College (270 votes) joined the compact, thereby guaranteeing that the national popular vote winner would also win the electoral college.{{sfn|Keyssar|2020|p=196}}<ref name="Laurent" /> Bennett and the Amar brothers "are generally credited as the intellectual godparents" of NPVIC.{{sfn|Neale|Nolan|2019|p=6}}

===Organization and advocacy===
Building on the work of Bennett and the Amar brothers, in 2006, [[John Koza]], a computer scientist and former elector, created the National Popular Vote Interstate Compact (NPVIC), a formal [[interstate compact]] that linked and unified individual states' pledges to commit their electoral votes to the winner of the national popular vote. NPVIC offered what it called “a framework for building support one state at a time as well as a legal mechanism for enforcing states' commitments after the threshold of 270 had been reached."{{sfn|Keyssar|2020|p=196}} Compacts of this type had long existed to regulate interstate issues such as water rights, ports, and nuclear waste.{{sfn|Keyssar|2020|p=196}}

Koza, who had earned substantial wealth by co-inventing the [[scratchcard]],{{sfn|Keyssar|2020|p=195}} had worked on lottery compacts such as the [[Tri-State Lottery]] with an election lawyer, Barry Fadem.{{sfn|Keyssar|2020|p=196}} To promote NPVIC, Koza, Fadem, and a group of former Democratic and Republican Senators and Representatives, formed a California [[501(c)(4)]] non-profit, [[National Popular Vote Inc.]] (NPV, Inc.).<ref name=NPVICHQ/>{{sfnm|1a1=Keyssar|1y=2020|1p=195|2a1=Neale|2a2=Nolan|2y=2019|2p=8}}<ref name="Laurent"/> NPV, Inc. published ''[[Every Vote Equal]]'', a detailed, "600-page tome"{{sfn|Keyssar|2020|p=195}} explaining and advocating for NPVIC,<ref>{{cite web |title=Every Vote Equal: A State-Based Plan for Electing the President by National Popular Vote |url=https://www.every-vote-equal.com/ |access-date=22 July 2024}}</ref>{{sfn|Neale|Nolan|2019|p=8}}<ref name="Laurent" /> and a regular newsletter reporting on activities and encouraging readers to petition their governors and state legislators to pass NPVIC.{{sfn|Neale|Nolan|2019|p=8}}  NPV, Inc. also commissioned statewide opinion polls, organized educational seminars for legislators, and hired lobbyists in almost every state seriously considering NPVIC legislation.{{sfn|Keyssar|2020|p=198}}

NPVIC was announced at a press conference in Washington, D.C., on February 23, 2006,{{sfn|Neale|Nolan|2019|p=8}} with the endorsement of former US Senator [[Birch Bayh]]; [[Chellie Pingree]], president of [[Common Cause]]; [[Rob Richie]], executive director of [[FairVote]]; and former US Representatives [[John B. Anderson|John Anderson]] and [[John Hall Buchanan, Jr.|John Buchanan]].{{sfn|Keyssar|2020|p=195}} NPV, Inc. announced it planned to introduce legislation in all 50 states and had already done so in Illinois.{{sfn|Keyssar|2020|p=195}}<ref name="Laurent" /> "To many observers, the NPVIC looked initially to be an implausible, long-shot approach to reform",{{sfn|Keyssar|2020|p=196}} but within months of the campaign's launch, several major newspapers including ''[[The New York Times]]'' and ''[[Los Angeles Times]]'', published favorable editorials.{{sfn|Keyssar|2020|p=196}} Shortly after the press conference, NPVIC legislation was introduced in five additional state legislatures,{{sfn|Neale|Nolan|2019|p=8}} "most with bipartisan support".{{sfn|Keyssar|2020|p=196}} It passed in the Colorado Senate, and in both houses of the California legislature before being vetoed by Governor [[Arnold Schwarzenegger]].{{sfn|Keyssar|2020|p=196}}

===Adoption===
{{further|#Bills and referendums}}
In 2007, NPVIC legislation was introduced in 42 states. It was passed by at least one legislative chamber in [[Arkansas]],<ref name="Arkansas">{{cite web|url=http://www.nationalpopularvote.com/state/ar|publisher=[[National Popular Vote Inc.]]|title=Progress in Arkansas|year=2009|access-date=June 6, 2008|archive-date=February 13, 2016|archive-url=https://web.archive.org/web/20160213182142/http://www.nationalpopularvote.com/state/ar|url-status=live}}</ref> [[California]],<ref name="CA SB 37"/> [[Colorado]],<ref name="CO SB 07-046"/> [[Illinois]],<ref name="IL HB 1685"/> [[New Jersey]],<ref name="NJ A 4225"/> [[North Carolina]],<ref name="NC S954"/> [[Maryland]], and [[Hawaii]].<ref name="HI SB 1956"/> Maryland became the first state to join the compact when Governor [[Martin O'Malley]] signed it into law on April 10, 2007.<ref name="O'Malley-signed"/>

By 2019, NPVIC legislation had been introduced in all 50 states.<ref name=progress /> {{#section:National Popular Vote Interstate Compact|As_of_month}}, the NPVIC has been adopted by {{#invoke:NPVIC status|states|passed|spell}} states and the District of Columbia. Together, they have {{#invoke:NPVIC status|EVs|passed}} electoral votes, which is {{#iferror:{{#invoke:NPVIC status|percent|passed}}|{{error|Value not available when editing this section in isolation}}}} of the Electoral College and {{#iferror:{{#invoke:NPVIC status|percent|passed|270}}|{{error|Value not available when editing this section in isolation}}}} of the 270 votes needed to give the compact [[coming into force|legal force]].

In Nevada, the Legislature passed Assembly Joint Resolution 6 in 2023. If the Nevada Legislature passes AJR6 again in 2025, then a proposal to ratify NPVIC via an amendment to Nevada's Constitution will appear on Nevada's November 2026 ballot.  If that amendment is approved by Nevada voters, then Nevada will provide its six electoral votes in support of the NPVIC.<ref>{{cite news |title=Is Nevada considering awarding its electoral votes to the presidential candidate who wins the popular vote? |last=Sims |first=Noel |language=en |publisher=The Nevada Independent |date=2023-05-31 |access-date=2024-09-15 |url=https://thenevadaindependent.com/fact-briefs/does-the-national-popular-vote-circumvent-the-constitution-1}}</ref>  

States where only one chamber has passed the legislation are Arizona, Arkansas, Michigan, North Carolina, Oklahoma, and Virginia. Bills seeking to repeal the compact in Connecticut, Maryland, New Jersey, and Washington have failed.<ref name=ncsl/>

No [[Republican Party (United States)|Republican]] governor has signed or allowed the compact to enter into law, though it has passed several Republican-led chambers and committees. This partisan split, if it continues, will affect the likelihood of the compact reaching the enactment threshold; see {{section link||Enactment prospects}}. The possibility of a partisan advantage to the compact is discussed in {{section link||Suggested partisan advantage}}.

===Reapportionment===
In April 2021, reapportionment following the [[2020 United States census|2020 census]] caused NPVIC members [[California]], [[Illinois]] and [[New York (state)|New York]] to each lose one electoral vote, and [[Colorado]] and [[Oregon]] to each gain one, causing the total electoral votes represented by members to fall from 196 to 195.

===Bills in latest session===
The table below lists all state bills to join the NPVIC introduced in a state's current or most recent legislative session.<ref name=ncsl>{{cite web|url=http://www.ncsl.org/research/elections-and-campaigns/elections-legislation-database.aspx|title=Elections Legislation Database|publisher=[[National Conference of State Legislatures]]|access-date=February 5, 2023}}</ref> That includes all bills that are law, pending or have failed. The "EVs" column indicates the number of electoral votes each state has.

<!-- INSTRUCTIONS:
 * When you update this section, also update the "pending" list at the very top of the article!
 * Use {{pending2}} ONLY when a bill has passed ALL committees to which it has been referred, and is ready for a floor vote, OR when a governor has pledged to sign a bill that is before them (give citation).
 * "Lower house", "Upper house" and "Executive" columns should have cells for each bill; "Status" column should have one merged cell for each state.
 * Bills should be removed (or moved to next section in the case of floor votes) ONLY when a new legislative session begins.
