Zohran Mamdani was elected mayor of New York City on Tuesday, 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 former Gov. Andrew 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.

President Donald Trump, who has long inserted himself in the politics of his hometown, followed the race closely. The president frequently dismissed Mamdani by falsely labeling him as a communist and said he would withhold funds from the city if he wins. He endorsed Cuomo on the eve of the election, bypassing Republican candidate Curtis Sliwa.

More than 2 million New Yorkers cast ballots in the contest, the largest turnout in a mayoral race in more than 50 years, according to the city’s Board of Elections.
