It's down to the wire in New York City's Democratic primary for mayor, with last-minute polls predicting widely divergent results. One poll predicts a surprising come-from-behind victory for Queens Assemblyman Zohran Mamdani.

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.

New York City voters will head to the polls today to cast ballots in the Democratic mayoral primary. There are 11 candidates on the ballot, including former New York Gov. Andrew Cuomo.
