Zohran Mamdani has won New York City’s Democratic mayoral primary. A new vote count Tuesday under the city’s ranked choice voting system confirmed the progressive legislator’s stunning upset of former Gov.

The latest Yale Youth Poll, conducted with YouGov among 645 voters between June 17 and 23 with a margin of error of ±5 percentage points, shows that in the final round of voting, Mamdani leads Cuomo among voters with income over $100,000 by 20 points, with 60 percent to Cuomo's 40 percent.
