NYC Mayor’s Race: City’s top unions endorse Mamdani, abandon Cuomo

Two of the city’s most influential unions endorsed presumptive Democratic mayoral nominee Zohran Mamdani on Friday, breaking with former Gov. Andrew Cuomo, whom they had supported before Tuesday’s primary of the 2025 New York City mayor’s race.

The unions, 32BJ SEIU and the Hotel and Gaming Trades Council (HTC), representing building service and hospitality workers, respectively, are the latest former Cuomo backers to shift their support to Mamdani.
