Mamdani Stakes His Political Clout in New York’s June 23 Primaries

This vote will show whether democratic socialist challengers can displace incumbents or signal the party’s tolerance for candidates tied to hardline positions on Israel and Gaza.

Overview

  • Mayor Zohran Mamdani endorsed three DSA‑aligned congressional challengers — Darializa Avila Chevalier, Brad Lander, and Claire Valdez — turning the June 23 primaries into a direct test of his influence.
  • Controversy over Israel and Gaza has become central to the races, with the Broadway Democrats refusing to back Avila Chevalier after saying she would not explicitly condemn Hamas and other candidates facing scrutiny for past protests or archived social posts.
  • Outside money and super PAC activity have flooded several contests, with nearly $8 million reported from an OpenAI‑connected pro‑AI super PAC in the crowded NY‑12 fight and large pro‑ and anti‑AI industry spending shaping that race.
  • Early voting produced 172,743 check‑ins across the five boroughs during June 13–21, and uneven youth turnout has left final results on Tuesday dependent on who shows up to vote on Election Day.
  • A string of outcomes could reshape New York’s Democratic delegation, deepen the rift between Mamdani’s left wing and House Democrats aligned with Hakeem Jeffries, and affect party messaging and vulnerability in competitive general election districts.
