Kentucky US Rep. Thomas Massie lost his Republican House primary Tuesday in another test of President Trump's power over his party after he handpicked challenger and ultimate winner Ed Gallrein to oust the incumbent. The result showed the president's persisting influence over GOP voters, adding to a growing number of Trump-backed primary challengers to defeat Republican lawmakers who angered him in his second term, the AP reports. According to early returns, Massie, who has served in Congress since 2012, received around 46% of the vote, with 54% going to the previously little-known Gallrein, the New York Times reports.
