The Washington Post is reporting that President Donald Trump's pick for Iowa governor lost a Republican primary. It said Trump had backed Rep. Randy Feenstra last week, calling him "MAGA all the way." The congressman, despite being better known than his rivals, was defeated by Zach Lahn, a farmer. Lahn had already drawn the support of some conservative activists critical of Feenstra and surged in polling toward the end of the race. This outcome is described as a blow to the president's dominance among Republicans.
