On a primary election day across multiple U.S. states, all eyes are fixed on Kentucky, where a high-stakes House contest has emerged as the most significant recent measure of former President Donald Trump’s unchallenged influence over the modern Republican Party. The battle pits seven-term incumbent Thomas Massie, a self-described libertarian and one of the few congressional Republicans willing to break publicly with Trump, against Trump-endorsed challenger Ed Gallrein, a retired Navy SEAL and local farmer.
Trump has pulled out all the stops to oust Massie, launching a months-long personal attack campaign that has seen the former president label the incumbent a disloyal “moron,” “nut job,” and “major sleazebag.” Speaking to reporters shortly after polls opened Tuesday, Trump doubled down on his criticism, claiming Massie is not a true Republican or libertarian and repeatedly mislabeling him a “Dumb-ocrat” to mock his occasional breaks from the party line.
What makes the contest particularly notable is that Massie maintains a pro-Trump voting record by almost any measure: he has aligned with Trump’s positions roughly 90 percent of the time during the former president’s second term, a statistic Massie has highlighted repeatedly throughout his campaign. Massie frames the race not as a challenge to Trump, but as a test of whether the Republican Party still has space for independent thinking among its elected officials. “Most of the people voting for me support President Trump like I do,” Massie told Fox News amid Trump’s latest round of attacks.
The incumbent has earned Trump’s wrath for a series of high-profile breaks with the party, including his opposition to U.S. military intervention in Iran and Venezuela, public criticism of large-scale aid packages to Israel, resistance to some elements of Trump’s policy agenda, and his support for releasing sealed documents connected to the late convicted sex offender Jeffrey Epstein.
The race has also made history as the most expensive House primary contest in U.S. history, with total ad spending surpassing $32 million. A large share of that spending has come from pro-Israel groups that have mobilized to defeat Massie over his critical stance on aid to the country.
A notable controversy emerged ahead of voting day when Defense Secretary Pete Hegseth made an in-person campaign appearance for Gallrein in Kentucky’s 4th Congressional District on Monday. Federal law bars federal employees from engaging in partisan political activity while on official duty, but Hegseth’s office clarified he was acting in a personal capacity and no taxpayer money was used for the trip. Trump later confirmed that Hegseth traveled to Kentucky just hours before the U.S. was on the cusp of launching a new military strike against Iran, an operation that was ultimately postponed.
The Kentucky contest follows a string of recent victories for Trump-aligned candidates over party dissidents: last week, Trump-backed challengers defeated Louisiana Senator Bill Cassidy—who voted to convict Trump during his 2021 impeachment trial after the Capitol riot—who failed even to advance to a runoff, while Trump allies defeated resistant state lawmakers in Indiana who pushed back against his redistricting priorities.
While Kentucky dominates national attention, primary contests are unfolding across multiple states Tuesday. In Georgia, voters are selecting nominees for U.S. Senate and governor, but the most closely watched races are for the state’s supreme court, where Democrats have mounted an unprecedented effort to unseat two incumbent justices. Former President Barack Obama and other top Democratic figures have endorsed the challengers, a race that carries outsize importance in the key swing state. No incumbent Georgia supreme court justice has lost a reelection bid in more than 100 years, making the contests a critical bellwether for Democratic momentum ahead of November’s general midterm elections.
