Republican Representative Thomas Massie lost his primary election in Kentucky on May 19, 2026, resulting in a victory for his opponent, Ed Gallrein. This election was viewed as a reflection of Donald Trump's influence within the Republican Party. The American Israel Public Affairs Committee (AIPAC) and affiliated super PACs contributed over $15.8 million to the race, which became the most expensive House primary in history, with total spending reaching $32 million.
Massie had previously accused his opponents of attempting to buy congressional seats, stating in his concession speech that he had faced pressure from various interests in Washington. He is known for his libertarian views and has often opposed U.S. foreign aid, particularly to Israel. AIPAC characterized Massie as the most anti-Israel Republican in the House, while public opinion polls indicate that support for Israel among Republicans has declined in recent years, especially among younger voters.
In his concession speech, Massie made a light-hearted remark about locating his opponent in Tel Aviv. AIPAC released a statement congratulating Gallrein and emphasizing the importance of a strong U.S.-Israel relationship, while also criticizing Massie's stance on the issue. The race was marked by negative advertising and accusations of antisemitism, with various groups engaging in extensive campaign efforts against Massie.
