Zohran Mamdani has won New York City’s Democratic mayoral primary. A new vote count Tuesday under the city’s ranked choice voting system confirmed the progressive legislator’s stunning upset of former Gov.

Mamdani, a 33-year-old state assemblyman representing northwest Queens, last month shocked the political establishment by trouncing the longtime front-runner, former Gov. Andrew Cuomo, whose name recognition, experience and support of billionaires and corporations, made him the favorite.

Zohran Mamdani declared victory in New York City’s Democratic mayoral primary Tuesday night after Andrew Cuomo conceded the race in a stunning upset. Mamdani is a progressive upstart who was virtually unknown when the contest began built a substantial lead over the more experienced but scandal-scarred former governor.
