Brad Lander Launches Primary Challenge to Rep. Dan Goldman in New York’s 10th

An expected endorsement from mayor‑elect Zohran Mamdani could help Lander consolidate progressive support in a district that favored the incoming mayor.

Overview

  • Lander’s team signaled the run with a supporter email and set a campaign kickoff for Wednesday evening, according to multiple reports.
  • His announcement messaging highlights arrests during protests at 26 Federal Plaza over ICE operations, casting activism as a central credential.
  • Mayor‑elect Mamdani is expected to endorse at the launch, a boost in territory where he won by wide margins in November.
  • Progressives Alexa Avilés and Yuh‑Line Niou are weighing bids, raising the prospect of a crowded left lane against the incumbent.
  • Goldman has filed reelection paperwork but not formally declared and has pushed a tax‑the‑ultra‑wealthy proposal as he faces a left‑flank challenge.
