Former governor Andrew Cuomo conceded the New York City mayoral race to Zohrahn Mamdani on Tuesday night, saying, “Congratulations to Zohran Mamdani.”

“Tonight was their night,” Cuomo told supporters at his election watch party in Manhattan.

Zohran Mamdani was elected mayor of New York City, capping a stunning ascent for the 34-year-old state lawmaker, who was set to become the city’s most liberal mayor in generations.

In a victory for the Democratic party’s progressive wing, Mamdani defeated Cuomo and Republican Curtis Sliwa. Mamdani must now navigate the unending demands of America’s biggest city and deliver on ambitious — skeptics say unrealistic — campaign promises.

With the victory, the democratic socialist will etch his place in history as the city’s first Muslim mayor, the first of South Asian heritage and the first born in Africa. He will also become the city’s youngest mayor in more than a century when he takes office on Jan. 1.
