Republican Thomas Massie lost his Kentucky primary after $20 million from pro-Israel and pro-Trump groups flooded the race, a bad sign for Republicans who break with Trump or criticize Israel.

• Massie lost by about 10,000 votes to Ed Gallrein, a Navy SEAL who skipped debates and barely campaigned but had tens of millions in attack ads behind him.
• AIPAC openly took credit, saying the win replaces an "outspoken detractor" of Israel with a pro-Israel voice. Marjorie Taylor Greene, the other Republican pushing to release the Epstein files, is also out.
• Massie had crushed past primaries with 75 to 81 percent of the vote even after Trump attacked him. The difference this time was money — $18.6 million for Gallrein versus $13.5 million for Massie, much of it from pro-Israel billionaires like Paul Singer and Miriam Adelson.
• The attack ads were AI-generated, including fake CCTV footage showing Massie entering a hotel room with AOC and Ilhan Omar. Massie lost voters 65 and up by 30 to 40 points.
• Without the pro-Israel money, Massie likely would have survived Trump's opposition like he did before.

Outlook: Republicans who criticize Israel or push the Epstein files now face a clear warning that big pro-Israel money can take them out, even in safe districts.
