Overview

  • On June 5, Rep. Alexandria Ocasio-Cortez announced she will rank Assemblymember Zohran Mamdani first among her five choices in the June 24 Democratic primary.
  • Post-endorsement surveys show Mamdani surging into second place and cutting into Cuomo’s 12-point lead in first-choice polling.
  • Mamdani’s platform centers on affordability measures including free city buses, rent freezes for stabilized tenants and universal subsidized child care.
  • At the June 4 debate, Mamdani pressed Cuomo on his record and joined other progressive candidates in highlighting the former governor’s establishment ties.
  • The June 24 primary employs ranked-choice voting, allowing New Yorkers to rank up to five candidates and reassign ballots from eliminated contenders.
