The June 23 New York primaries weren’t just a win for three progressive candidates—they were a sledgehammer to the Democratic establishment’s grip on urban congressional seats. Mayor Zohran Mamdani’s endorsements didn’t just secure victories; they upended decades of party loyalty, unseating incumbents who thought their positions were unassailable. This isn’t a one-off—it’s the payoff of a year-long grassroots movement that began with Mamdani’s own upset mayoral win over Andrew Cuomo.
Brad Lander, Claire Valdez, and Darializa Avila Chevalier all claimed decisive wins. Lander took two-thirds of the vote in NY-10, ousting two-term Rep. Dan Goldman, who relied on AIPAC donations. Avila Chevalier narrowly beat Adriano Espaillat, the powerful Congressional Hispanic Caucus chair. Valdez won the open NY-7 seat against Antonio Reynoso, despite his backing from Rep. Nydia Velázquez and the Working Families Party.
All three ran on unapologetically progressive platforms: Medicare for All, public housing, and sharp criticism of U.S. military aid to Israel. Lander, a Jewish progressive, called Biden’s “hug Bibi” strategy a “catastrophic mistake” and accused the party of complicity in genocide. Valdez, a DSA member, vowed to let working people “run the table.” Avila Chevalier, a community organizer, focused on immigrant rights and expanding the social safety net.
Behind the scenes, the establishment’s playbook crumbled. Espaillat had backing from House Minority Leader Hakeem Jeffries, but Mamdani’s on-the-ground campaigning for Avila Chevalier shifted voter sentiment. Goldman’s AIPAC ties became a liability, as voters rejected pro-Israel hardliners. The districts where Mamdani won big in his mayoral race were exactly where his endorsees triumphed—proof of a loyal, organized base.
The Israel policy divide was the key fault line. Incumbents stuck to traditional party support for Israel, while Mamdani’s picks demanded an end to military aid. This split isn’t just local—it’s a national rift that’s tearing the Democratic Party apart. Voters in these districts clearly chose the progressive wing over the establishment.
The Democratic establishment will either adapt to this socialist surge or lose more urban congressional seats in 2028.
