Trump-backed Feenstra concedes Iowa governor primary to outsider Lahn

Randy Feenstra conceded to businessman Zach Lahn on Tuesday night after Iowa Republicans rejected the late push from President Donald Trump in the race for governor. Feenstra called Lahn to congratulate him and then told supporters at a campaign watch party in Hull that he was ending his bid, even though the Associated Press had not yet called the race.

The result capped a five-way Republican contest that also included former Iowa Department of Administrative Services director Adam Steen, former state Rep. Brad Sherman and state Rep. Eddie Andrews. Feenstra, a three-term U.S. House member from Iowa’s 4th Congressional District, had entered the race with the advantage of name recognition and backing from major GOP figures, including former Gov. Terry Branstad and Trump, who endorsed him just four days before the June 2 primary.

Lahn, by contrast, ran as a political outsider. A businessman and farmer who had never held public office, he built his campaign around a direct challenge to the Republican establishment. He also aligned himself with the Make America Health Again movement associated nationally with Robert F. Kennedy Jr., and pressed GOP leaders over water quality and cancer rates, issues that have become politically potent in Iowa.

The primary was competitive from the start because Gov. Kim Reynolds decided in 2025 not to seek reelection, leaving Iowa without an incumbent on the Republican ballot for the first time in more than a decade. That open-seat scramble made the governor’s race a central prize for Republicans and Democrats alike. The Cook Political Report rated the general election as a toss-up, and Democrats have not won Iowa’s governor’s office since 2006.

Lahn’s path to the nomination was aided by money as well as message. He outraised Feenstra during the Jan. 1 to May 14 fundraising period, helped by a $2 million personal loan that gave him the resources to compete statewide. Feenstra also faced criticism from some primary rivals for holding few public events and skipping debates, weaknesses that helped fuel the outsider argument Lahn carried into the final stretch.

Lahn is now expected to face state Auditor Rob Sand in November. Sand was unopposed in the Democratic primary and enters the general election as the only Democrat holding statewide office in Iowa, setting up a contest that will test whether Trump’s endorsement still decides Republican primaries, or whether Iowa voters are willing to break from it when the challenger is better aligned with the mood of the party.
