Zach Lahn Defeats Trump-Endorsed Randy Feenstra in Iowa GOP Primary

Outlets agree Zach Lahn defeated Rep. Randy Feenstra in Iowa’s Republican gubernatorial primary after President Trump endorsed Feenstra. Left-leaning outlets cast the loss as a rebuke to Trump and a question about his influence. Center outlets likewise focus on limits to Trump’s influence, while connecting Lahn’s win to MAHA’s farm and pesticide platform. Right-leaning outlets emphasize the unusual loss for a Trump-endorsed candidate, with one also presenting it as the end of Trump’s cited endorsement win streak.
