New York Democrats’ intra-party clash tests left-wing surge against the establishment
New York’s congressional primaries are a battleground between the establishment and a rising left-wing insurgency, with Jeffries backing incumbents in NY-10 and NY-13 while Mamdani backs left-wing challengers (Lander in NY-10; Avila-Chevalier in NY-13) and Valdez in NY-7. The NY-12 Nadler seat pits Micah Lasher against Alex Bores amid heavy outside spending from Think Big and Jobs and Democracy PAC. The contests feature cross-endorsements, divergent policy signals, and money flowing from national figures and groups, complicating the left-versus-centrist dynamic within the party.
