Iowa's 2026 congressional elections reshape the state's political landscape after high-profile departures and shifts.
In short: On November 3, 2026, Iowa voters will decide the future of the state's four U.S. House seats. With incumbents retiring to pursue higher office and others facing intense competition, the primary elections held on June 2, 2026, set the stage for a pivotal contest across all four congressional districts.
The 2026 election cycle in Iowa is defined by significant turnover and strategic maneuvering. In the 2nd district, incumbent Republican Ashley Hinson, who secured 57.1% of the vote in 2024, opted against seeking re-election to instead run for the U.S. Senate. Similarly, in the 4th district, Randy Feenstra, who had won re-election with 67.0% of the vote in 2024, announced his retirement on October 28, 2025, to pursue a gubernatorial bid. Feenstra ultimately placed second in the Republican primary, losing by a margin of less than 1%.
Elsewhere, the political battles remain tightly contested. In the 1st district, Republican Mariannette Miller-Meeks faces a challenging environment after her 2024 re-election, which saw her win with 50.0% of the vote—the narrowest margin of any incumbent House Republican that year. She faces a field that includes former state representative Christina Bohannan and independent financial advisor Michael Bridgford. Meanwhile, in the 3rd district, incumbent Republican Zach Nunn, who won 51.8% of the vote in 2024, is running for re-election against a field that includes state senator Sarah Trone Garriott.
The candidate pools reflect a mix of experienced legislators and political newcomers. The 2nd district race features figures like former U.S. representative Rod Blum and former U.S. attorney Kevin Techau, while the 4th district race includes candidates like Siouxland Chamber of Commerce president Chris McGowan, who received endorsements from figures such as former Iowa House majority leader Matt Windschitl. These races, held alongside broader state and local contests, highlight the shifting dynamics within Iowa's congressional representation as the state navigates the departure of established incumbents and the rise of new political contenders.
