Andrew Cuomo concedes New York City Democratic mayoral primary to Zohran Mamdani

Mamdani, a 33-year-old democratic socialist member of the state Assembly, started to pull ahead with more than an estimated 80% of ballots counted.

Mamdani would be the city's first Muslim and Indian American mayor if elected.

His army of young canvassers relentlessly knocked on doors throughout the city seeking support. Posters of his grinning mug were up on shop windows. You couldn't get on social media without seeing one of his well-produced videos pitching his vision - free buses, free child care, new apartments, a higher minimum wage and more, paid for by new taxes on rich people.

That youthful energy was apparent Tuesday evening, as both cautiously optimistic canvassers and ecstatic supporters lined the streets of Central Brooklyn, creating a party-like atmosphere that spread from poll sites into the surrounding neighborhoods.
