NYC Mayoral Primary Tightens as Mamdani Gains Progressive Backing

Bernie Sanders’s endorsement, joined by Alexandria Ocasio-Cortez’s support, is boosting Mamdani’s challenge just as early voting begins.

Overview

  • Early voting commenced June 14 with 66,361 ballots cast through day two, reflecting high participation across all five boroughs.
  • A Marist poll of 1,350 likely Democratic voters found Cuomo leading first-choice preferences 38% to Mamdani’s 27%, with 11% undecided and ranked-choice projections narrowing the gap to 55%–45%.
  • Mamdani secured Sanders’s backing on June 17 and earlier endorsement from Ocasio-Cortez, and has cross-endorsed with Brad Lander and Michael Blake to consolidate progressive rankings.
  • Some early voters questioned Mamdani’s top placement on the ballot, prompting calls for greater transparency in the NYC Board of Elections’ random drawing process.
  • The race has become a referendum on party direction, pitting Cuomo’s centrist focus on affordability and public safety against Mamdani’s progressive agenda of rent freezes and city-owned services.
