Rep. Thomas Massie (R-Ky.) faces his toughest political test on Tuesday as he takes on a primary challenger backed by President Donald Trump, a race that will gauge the limits of the president's influence over the Republican Party.
Massie, a libertarian-leaning incumbent first elected in 2012, is up against retired Navy SEAL Ed Gallrein. But the real firepower against Massie comes from the White House. Trump has repeatedly attacked Massie on social media, calling him “the worst Congressman in the long and storied history of the Republican Party” and urging voters to “vote him out of office.”
The president’s animus stems from Massie’s independent streak. Massie has been a vocal critic of government spending and foreign interventions, including Trump’s escalation against Iran. He also teamed up with Rep. Ro Khanna (D-Calif.) to force the release of files related to convicted sex offender Jeffrey Epstein, a move that angered Trump, who has faced persistent questions about his past ties to Epstein.
In a highly unusual move, Defense Secretary Pete Hegseth traveled to Kentucky on Monday to campaign for Gallrein. Hegseth insisted he was acting as a “private citizen,” but his presence underscored the extraordinary lengths the administration is willing to go to oust Massie. “Warfighters understand that in the middle of a fight you don’t weaken your own side,” Hegseth said, praising Gallrein’s military service.
Despite the White House’s full-court press, Massie has deep roots in his district and a loyal following among libertarian-minded Republicans. Kentucky has a history of electing mavericks like Sen. Rand Paul, who shares Massie’s ideology. State Rep. Steven Doan (R) predicted Massie would survive, arguing that Kentucky voters are used to “intra-party factions” and can support a candidate without agreeing on every issue.
But the money against Massie is staggering. Outside groups have poured more than $14 million into the race, much of it from pro-Israel organizations. Massie has pointed to a Politico report quoting Sam Markstein of the Republican Jewish Coalition saying, “We expect to win on Tuesday.” Massie fired back on social media, calling Gallrein a “puppet” of these groups.
Polls show a tight contest. Of five major surveys this month, three show Gallrein leading, one is a dead heat, and one gives Massie a one-point edge. Massie’s fate may hinge on younger Republican voters, who tend to be more skeptical of Israel and may be less swayed by Trump’s endorsements.
The outcome will be closely watched as a bellwether for Trump’s grip on the GOP. Recent primaries have shown the president’s power to punish dissenters: Sen. Bill Cassidy (R-La.) lost badly after voting to convict Trump in the 2021 impeachment, and several Indiana state senators who defied Trump on redistricting were ousted earlier this month. If Massie survives, it would be a rare break from that pattern.
Trump’s national approval remains low, at 37% among registered voters according to a recent New York Times/Siena College poll, but his support among Republicans is solid. As GOP strategist Dan Judy put it, “It’s Donald Trump’s party, there’s no question about that.” Tuesday’s vote will show whether that still holds true in a district where the incumbent has a long history and a fiercely independent streak.
