In a remarkable political shift, candidates endorsed by New York's democratic socialist Mayor Zohran Mamdani swept the Democratic primaries, marking a significant change in pro-Israel politics.5
This clean sweep included victories for Brad Lander, Claire Valdez, and Darializa Avila Chevalier, all of whom have openly criticized Israel's actions in Gaza.3
Lander defeated incumbent Dan Goldman with 65.7% of the vote, while Valdez and Chevalier also secured their respective districts, showcasing Mamdani's growing influence within the party.
Mamdani stated, “The old politics that got us into this crisis is not the politics that’s going to get us out of this crisis.”
The results reflect a broader trend among progressives, as they gain traction in a party traditionally aligned with pro-Israel policies. “This signals a substantial shift in policy toward Israel,” noted Democratic strategist Basil Smikle.
Critics, however, caution that this shift may not resonate with all Democratic voters, as former Rep. Steve Israel remarked, “Critics of Israel on the left are having a moment, but that doesn’t mean they represent a majority of congressional Democrats.”7
The implications of these primaries extend beyond New York, as they may influence the Democratic party's stance on Israel leading into the 2026 elections. Jon Paul Lupo, a Democratic strategist, emphasized, “In a Democratic primary, the people who are against the war in Gaza have a massive political advantage in 2026.”
As Mamdani's allies take office, the future of pro-Israel politics within the Democratic party remains uncertain, with some fearing a stronger foothold for anti-Israel sentiments.
“Candidates backed by New York's democratic socialist Mayor Zohran Mamdani won all three Democratic primaries, marking a significant shift in the party's direction. This outcome reflects growing influence for progressive politics in a city traditionally aligned with pro-Israel stances.”
