  • Even though it is an even-district year, Senate District 49 was on the ballot due to the 2012 redistricting.[1]
  • The results of the election in Senate District 22 were counted, but not canvassed due to the death of incumbent candidate Pat Ward.[2]

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.


The President of the Senate presides over the body, whose powers include referring bills to committee, 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.[4] 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).[5] 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 Charles Schneider of the 22nd District. The Majority Leader is Republican Jack Whitver of the 19th District. The Minority Leader is Democratic Janet Petersen of the 18th District.
