Democrat Zohran Mamdani has been elected New York City’s first Muslim mayor and its youngest in generations.

The 34-year-old state lawmaker harnessed enthusiasm and social media savvy to become a rising star in the party, but his candidacy sparked an ideological divide.

He defeated Independent candidate and former Democratic Gov. Andrew Cuomo, who attempted a political comeback four years after resigning in scandal.

Democratic Rep. Alexandria Ocasio-Cortez, one of Mamdani’s most prominent backers, said New Yorkers would fight back.

"We’re going to stand up to bullies and thugs in the White House," she told reporters.

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.
