In a closely contested Republican primary for governor in Iowa, businessman Zach Lahn emerged victorious over Rep. Randy Feenstra, who had the backing of former President Donald Trump. With 98% of the expected vote counted, Lahn secured 37.8% of the vote compared to Feenstra's 37%. This loss is notable as it marks the first time a Trump-endorsed candidate has lost in the midterm primaries. Lahn's success can be attributed to his alignment with Health and Human Services Secretary Robert F. Kennedy Jr.'s 'Make America Healthy Again' movement and an endorsement from former Rep. Steve King. Feenstra, who positioned himself as a loyal Trump ally, faced criticism for not winning his own district convincingly. As Lahn prepares for the general election against Democratic nominee Rob Sand, who has been building a strong campaign, concerns about Trump's economic policies linger among Iowa Republicans. The political landscape is evolving, with some Republicans expressing a willingness to support Sand, who promises to be a governor 'for all of Iowa.'
