Thomas Massie vs Trump‑backed challenger in pricey Kentucky GOP primary

Incumbent Republican Rep. Thomas Massie is facing a high‑profile primary challenge in Kentucky’s 4th Congressional District. President Donald Trump has pledged support for Navy SEAL Ed Gallrein, the Trump‑backed candidate, criticizing Massie for opposing the president’s Iran strikes, voting against the “big, beautiful bill,” and pushing to release the Jeffrey Epstein files. Trump has called Massie a “moron” and a “complete and total disaster.”

Gallrein’s campaign is being heavily funded by pro‑Israel groups, with AIPAC and the Republican Jewish Coalition spending between $5.7 million and $9.8 million, and total advertising for the race exceeding $25 million—the most expensive House primary in U.S. history. Colorado Rep. Lauren Boebert publicly endorsed Massie, despite Trump’s pressure, stating she supports both Massie and the president.

Voters in the district are weighing loyalty to Trump against Massie’s independent record. Polls show Gallrein ahead 48‑43 ahead of the May 19 primary. Massie has framed the contest as a referendum on whether “Israel gets to buy seats in Congress,” alleging foreign influence in U.S. elections.
