With 95% of ballots counted, Mamdani was leading with 43% of the vote, though a final result awaits the completion of ranked-choice tabulations.Cuomo, attempting a political comeback after resigning in 2021 amid a sexual harassment scandal, conceded shortly after polls closed. “Tonight is his night.

Cuomo too has left open the possibility of continuing as an independent.New York is a key Democratic stronghold, widely regarded as one of the party’s “Big Three” power bases, along with California and Illinois.Born in Uganda to Indian parents, Mamdani’s campaign resonated with younger voters, driven by promises of free buses, universal childcare, rent freezes, and taxing the wealthy. His grassroots strategy and social media savvy helped him gain endorsements from progressives like Bernie Sanders and Alexandria Ocasio-Cortez.Supporters celebrated outside polling stations across Central Brooklyn, dancing and handing out iced tea in the sweltering heat. “It’s 100 degrees outside and it’s a vibe,” said Amani Kojo, a 23-year-old first-time voter. “It feels very electric seeing all the people around, the flyers, all the posts on my Instagram all day.”While Cuomo and others labelled Mamdani inexperienced and unqualified, especially for his pro-Palestinian stance, Mamdani hit back sharply. “To Mr. Cuomo, I have never had to resign in disgrace,” he said during one debate.
