A political earthquake shook Iowa Republicans on Tuesday as an obscure farmer backed by the Make America Healthy Again movement pulled off a stunning upset against President Donald Trump’s preferred candidate in the race to succeed retiring Gov. Kim Reynolds.
Zach Lahn, a father of seven and first-time statewide candidate, narrowly defeated Republican Congressman Randy Feenstra in one of the closest and most surprising gubernatorial primaries of the election cycle. With more than 95 percent of votes counted, Lahn captured 37.79 percent of the vote compared to Feenstra’s 37.01 percent, a margin of fewer than 2,000 votes in a crowded five-candidate field.
The victory instantly elevated Lahn from political outsider to Republican nominee for governor and highlighted the growing influence of the Make America Healthy Again movement inside the GOP.
Speaking to supporters after his victory, Lahn framed the result as a grassroots rebellion against political insiders and establishment power brokers.
We did it!!!
Thank you IOWA!
IOWA FIRST!

“How about this? We the people!” Lahn declared to cheering supporters.
“I don’t have to tell you this but nobody thought that this could be done. We were outspent, opposed by the establishment, told to wait our turn.”
“Well, tonight the people of Iowa had something to say about that. That we’re not going to wait anymore!”
Throughout the campaign, Lahn leaned heavily into MAHA themes, focusing on public health concerns, chronic disease, and what he described as the excessive influence of large corporations in agriculture and medicine.
During his election-night speech, he returned to one of his signature issues: Iowa’s rising cancer rates.
“Iowa has the fastest-growing cancer rate in the world. We all know something is terribly wrong,” Lahn said. “But too many politicians from Washington, D.C., to Des Moines have had their heads stuck in the sand while Big Ag and Big Pharma have printed money.”
“This will not go on when I’m governor.”
Lahn argued that state leaders have failed to seriously investigate potential environmental and agricultural factors contributing to health problems across Iowa. He called for greater scrutiny of major industries and pledged to direct state resources toward understanding and combating what he described as a growing public health crisis.
His campaign gained momentum with backing from MAHA Action and Turning Point Action, organizations that mobilized activists behind his outsider candidacy. Prominent supporters portrayed Feenstra as too closely aligned with pharmaceutical interests, a criticism that became a recurring theme during the race.
Alex Clark, a prominent MAHA commentator affiliated with Turning Point USA, openly campaigned against Feenstra after Trump endorsed the congressman.
“RUN DON’T WALK. VOTE LAHN!!!!!” Clark urged supporters on social media.
Following the upset, Turning Point Action President Erika Kirk celebrated the result as a major victory for both the MAGA and MAHA movements.
“Congratulations to Zach Lahn on his victory! He will be a great Governor for all Iowans,” Kirk wrote. “Proud of our team and the work ahead to deliver more MAGA and MAHA wins for the President.”

The outcome is particularly notable in Iowa, a state whose economy is deeply tied to agriculture. Iowa leads the nation in corn production and ranks second in soybean production. Both industries have occasionally found themselves at odds with portions of the MAHA movement, which has raised concerns about products such as seed oils, herbicides, and other agricultural inputs.
Lahn has been outspoken on those issues. During a lengthy interview earlier this year with Tucker Carlson, he discussed pesticide use, Parkinson’s disease, artificial intelligence, land ownership, and what he views as growing health challenges facing rural America.
Despite Tuesday’s upset, Trump did score another victory elsewhere on the Iowa ballot. Republican Rep. Ashley Hinson, another Trump-endorsed candidate, cruised to victory in the GOP Senate primary and now advances to the general election as the favorite to succeed retiring Sen. Joni Ernst.
Lahn now turns his attention to Democratic Iowa Auditor Rob Sand, who secured his party’s nomination without opposition. Political analysts expect the governor’s race to be highly competitive despite Iowa’s recent Republican lean. The Cook Political Report currently rates the contest as a toss-up, setting the stage for one of the most closely watched gubernatorial races in the country.
