AIPAC, Pro-Israel Candidates Show Strong Support in Primaries

AIPAC and allied pro-Israel candidates recorded a major political victory in Tuesday’s primaries, as several races showed the growing power of organized pro-Israel spending in shaping congressional contests.

The most prominent result was the defeat of Rep. Thomas Massie, who represented Kentucky’s 4th District for 14 years and was one of Congress’s most outspoken Republican critics of Israel. Massie lost the GOP primary to Ed Gallrein, a former Navy SEAL backed by President Donald Trump and supported by heavy outside spending from pro-Israel and Trump-aligned groups.

Massie had long opposed foreign aid, including US military assistance to Israel, and had repeatedly criticized American involvement in Middle East conflicts. His defeat marks one of the clearest examples this cycle of pro-Israel political organizations translating campaign spending and field pressure into electoral results.

AIPAC has changed its political strategy sharply in recent years. After decades of working largely through relationships, endorsements and behind-the-scenes pressure, it has increasingly used political action committees and outside spending to intervene directly in primaries.

That shift has made AIPAC one of the most influential forces in congressional elections. Its electoral operation now focuses not only on supporting reliable pro-Israel candidates, but also on defeating candidates it views as hostile to the US-Israel alliance.

In crowded primaries, AIPAC and allied groups have learned to use large-scale spending, voter targeting and endorsements to shape the field. The results so far suggest that while anti-Israel rhetoric has gained traction in some progressive circles and on social media, it has not yet translated consistently into broad electoral success.

Trump’s role remains important, particularly in Republican primaries. In Kentucky, he made Massie’s defeat a personal objective and repeatedly attacked him in the closing days of the campaign. His endorsement helped consolidate the GOP base behind Gallrein.

But the broader story for Israel supporters in Washington is AIPAC’s continued ability to operate across the political map. The group has become a central player in both Republican and Democratic primaries, defending pro-Israel incumbents and backing challengers against candidates it considers anti-Israel.

The results were not uniformly favorable for pro-Israel groups. In Pennsylvania’s 3rd District, state Rep. Chris Rabb remained an example of the challenge AIPAC faces in deep-blue districts, where progressive candidates can build support around sharp criticism of Israel.

Still, the overall trend from the primaries so far points to AIPAC’s continued strength. Its election machine has shown it can turn donor networks, strategic spending and political discipline into concrete wins.

For pro-Israel advocates, the night reinforced a central lesson: hostile rhetoric online does not necessarily reflect the balance of power in actual elections. In many races, especially where AIPAC can concentrate resources, support for Israel remains a powerful advantage and opposition to Israel can still carry a high political cost.
