The 2022 Iowa Senate elections were held on November 8, 2022, to elect members of the Iowa Senate from 25 odd-numbered districts. Senators serve four-year terms in single-member constituencies, with half of the seats up for election each cycle. Primary elections were held on June 7.[1]
Note: If a district does not list a primary, then that district did not have a competitive primary (i.e., there may have only been one candidate file for that district).[4]
Democratic senator Jackie Smith[a] was redistricted from District 7 to 1. No Democratic candidate filed in District 7; therefore, the district was an automatic gain for Republicans.
Republican state senator Zach Nunn decided to run for the US House of Representatives in Iowa's 3rd congressional district instead of re-election in this district in the Iowa State Senate. No Republican candidate filed in District 15; therefore, the district was an automatic gain for Democrats.
Republican senator Annette Sweeney[m] was redistricted from District 25 to 27. No Republican candidate filed in District 25; therefore, the district was an automatic gain for Democrats.
Republican senator Chris Cournoyer[q] was redistricted from District 49 to 35. No Republican candidate filed in District 49; therefore, the district was an automatic gain for Democrats.
