Will KY Rep Thomas Massie beat his Trump endorsed opponent in the May 19 primary?
56% of users predicted YES — the community missed this one. 39 predictions cast.
Rep. Thomas Massie of Kentucky lost his Republican primary on May 19, 2026, to Navy veteran Ed Gallrein in the state's 4th Congressional District, ending a 14-year congressional tenure. Gallrein carried the race after receiving a direct endorsement from President Trump, who had repeatedly targeted Massie for votes against the administration's agenda, including opposition to the president's signature tax legislation, support for releasing Jeffrey Epstein files, and public criticism of the Iran military campaign.
The race drew extraordinary outside spending, with pro-Israel interest groups funneling millions of dollars into advertising against Massie, who had been among Congress's most outspoken critics of U.S. foreign policy commitments. The combination of Trump's personal endorsement and concentrated outside-group funding proved decisive in a district where Republican primary voters have closely tracked the president's preferences.
Massie's defeat is the latest in a series of incumbent losses to Trump-backed challengers in the 2026 primary cycle, reinforcing the president's demonstrated ability to discipline intra-party dissent. The Predict Six community predicted YES at 56% — that Massie would survive — but the outcome went the other way.
