Representative Thomas Massie's defeat in Kentucky primaries was amplified by tens of millions of dollars spent by pro-Israel groups including a super PAC tied to AIPAC. The congressman's "Tel Aviv" remark during his concession speech alluded to this spending, which targeted his long-standing opposition to foreign aid to Israel and criticism of the country's conduct in the Middle East.

Israel debates have become central to midterm campaigns across the country, dividing both parties. AIPAC-affiliated super PACs have already spent millions this election cycle, with more expected in upcoming races in California, New York, and Michigan. These expenditures have sometimes backfired, helping progressive candidates win primaries and indicating deep discontent toward Israel within the Democratic base.

New polling shows declining support for Israel among younger voters in both parties. Only one-third of Republicans aged 18-44 support additional aid to Israel, while 56% of younger Democrats believe their party has been too supportive. This shifting sentiment is reshaping campaign strategies and fundraising approaches, with more than two dozen ads this year featuring messages focused on Israel, Gaza, or Palestinians.
