Rep. Randy Feenstra lost the GOP primary for Iowa governor on Tuesday, a shocking upset after he earned President Donald Trump’s last-minute endorsement.

Feenstra, who was narrowly defeated by rival Zach Lann, conceded and called to congratulate him before results were official.

The three-term representative outspent Lahn, a businessperson and former GOP operative, by nearly $1 million and leaned heavily into his MAGA credentials during the primary.

The loss is a blow for Trump, who has seen most of his chosen candidates this cycle sail to victory or advance to runoff elections — until now. He backed Feenstra just four days before the primary, a last-ditch attempt to bolster his loyal GOP ally in a race that became increasingly competitive in the final stretch. Feenstra had asked for Trump’s endorsement earlier this year and began calling himself a “Trump conservative” in ads even before receiving the president’s backing.

The race kicked off when Republican Gov. Kim Reynolds decided against running for reelection, with Feenstra, Lahn and three other candidates competing for the GOP nomination. Feenstra, who boasts a long record in the state and in Congress, was widely viewed as the front-runner, though the latest primary polling revealed he was on shaky standing.

Lahn has never held public office, but spent years working in Republican politics and running campaigns in Montana and Colorado. In this race, he positioned himself as a political outsider. „I’m my own biggest donor and I cannot be bought,” he said in one face-to-camera ad. “I’m running because career politicians, special interests and corporate giants have betrayed Iowans.”

Lahn is a native Iowan but spent many years out of the state, most recently opening a private school in Wichita, and reportedly voted in Kansas from 2018 through 2022.

Lahn will face off with Democrat Rob Sand in November in the marquee race, with Iowa Democrats eager to win the governor’s mansion for the first time since 2006. Sand, the Iowa state auditor, is the lone Iowa Democrat to hold statewide office.
