Iowa's 2026 General Election Features Open Seats for Governor and the U.S. Senate
In short: On November 3, 2026, Iowa voters will decide the future of the state's executive offices, all four U.S. House seats, and a critical U.S. Senate vacancy. With both the governor and the incumbent senator declining re-election, the political landscape is shifting, creating high-stakes contests that could influence the national balance of power.
The 2026 election cycle in Iowa is defined by significant turnover in top-tier positions. Senator Joni Ernst, who secured her seat in 2020 with 50.88% of the vote, announced she would not seek a third term. This vacancy has drawn intense interest, as Democrats view the seat as a potential pickup to help regain their Senate majority. The race gained national attention following controversial remarks Ernst made regarding Medicaid, which prompted several prominent Democrats, including state Senator Zach Wahls, to enter the contest. On the Republican side, Representative Ashley Hinson emerged as the primary frontrunner after receiving an endorsement from Donald Trump.
The gubernatorial race is equally transformative, as incumbent Governor Kim Reynolds opted against running for a third term. The Democratic nominee, state auditor Rob Sand—the only Democrat to win statewide in 2022—is running alongside his chosen partner, Dave Muhlbauer. The Republican nomination saw an unexpected outcome when Zach Lahn defeated Representative Randy Feenstra, despite Feenstra holding an endorsement from Donald Trump. Lahn, who secured the backing of Turning Point Action, is running with state representative Derek Wulf.
Beyond these executive and federal races, the composition of the Iowa legislature is at stake. All 100 seats in the state House and half of the state Senate seats are up for election. Currently, Republicans maintain a dominant position with a supermajority in the lower chamber and a majority in the upper chamber. However, observers suggest that if the state shifts toward the left during these midterms, Democrats could potentially narrow these margins. Meanwhile, other statewide offices, including the attorney general, secretary of state, and treasurer, feature incumbents or challengers vying to shape the state's administrative future.
