The Iowa Senate is the upper house of the Iowa General Assembly. There are 50 seats in the Iowa Senate, representing 50 single-member districts across the state of Iowa with populations of approximately 60,927 per constituency, as of the 2010 United States censusTemplate:Dated maintenance category (articles)Script error: No such module "Check for unknown parameters"..[1] Each Senate district is composed of two House districts. The Senate meets at the Iowa State Capitol in Des Moines.

Unlike the lower house, the Iowa House of Representatives, senators serve four-year terms, with no term limits. Terms are staggered so that half the Senate is up for reelection every two years.

Leadership

The President of the Senate presides over the body, whose powers include referring bills to committees, recognizing members during debate, and making procedural rulings. Unlike the more powerful Speaker of the Iowa House of Representatives, the Senate President cannot appoint committee chairmanships or shuffle committee memberships.[3] The lieutenant governor of Iowa was the presiding officer of the Senate until 1988, when an amendment to the Constitution of Iowa was passed in a referendum (effective from 1991).[4] The other partisan Senate leadership positions, such as the Majority and Minority leaders, are elected by their respective party caucuses to head their parties in the chamber.

The President of the Senate is Republican Amy Sinclair of the 12th District. The Majority Leader is Republican Jack Whitver of the 23rd District. The Minority Leader is Democrat Pam Jochum of the 36th District.[5]
