New York, United States - September 06, 2023 Video: Mamdani during talk at Democratic Socialists of America on 2023. Zohran Mamdani declared victory in New York City’s Democratic mayoral primary Tuesday night after Andrew Cuomo conceded the race in a stunning upset, as the young, progressive upstart who was virtually unknown when the contest began built a substantial lead over the more experienced but scandal-scarred former governor. Though the race’s ultimate outcome will still be decided by a ranked choice count, Mamdani took a commanding position just hours after the polls closed. With victory all but assured, Mamdani, a 33-year-old democratic socialist who ran an energetic campaign centered on the cost of living, told supporters, “I will be your Democratic nominee for the mayor of New York City.”
