Zohran Mamdani (D) currently leads Andrew Cuomo (D) in the Democratic primary for mayor of New York City, which was held on June 24, 2025. 

As of June 25, at 10:50 AM ET, with 93% of the vote counted, Mamdani has 43% of the vote to Cuomo’s 36% of the vote. Cuomo conceded on election night. New York City calculates ranked-choice voting totals a week after the election. This means the results of voting after the first round will not be added to the total until July 1.

Incumbent Eric Adams (D) was first elected in 2021. He initially ran in the primaries for re-election, but withdrew on April 3 to run as an independent.

The New York Times’ Nicholas Fandos and Lisa Lerer wrote, “The clash consuming New York City is one that has become almost routine in Democratic politics. On one side stands a moderate pragmatist who first took public office three decades ago. On the other is a democratic socialist half his age who has leaped past more seasoned rivals and captured the imagination of the left.”

Candidate endorsements became a factor, and City & State NY’s Sahalie Donaldson, Annie McDonough, and Holly Pretsky wrote that as the race progressed, “Alliances [began] to solidify.” Former mayor Michael Bloomberg (D) endorsed Cuomo, and Columbia University Prof. Ester Fuchs said, “Bloomberg is the most critical and important endorsement for Cuomo in the primary. It’s a seal of approval for moderate voters who care about effectively governing the city.” Rep. Alexandria Ocasio-Cortez (D) endorsed Mamdani, and City University of New York Prof. John Mollenkopf said the endorsement could “make some difference. And in this tight race, some difference is valuable.”

This was the third election in the city that utilized ranked-choice voting. The system allowed voters to rank up to five candidates, and if their first candidate were eliminated, their vote would be transferred to a different candidate. Voters could have picked only one candidate or ranked fewer than five. This system applied only to the primary election.

The New Republic’s Grace Seger wrote before the election, “In these final weeks, the mayoral hopefuls are working to tailor their campaigns to train voters on what they need to do when they enter their voting booths.” On June 13, Brad Lander and Zohran Mamdani endorsed each other.

On June 16, Mamdani and Michael Blake (D) endorsed each other’s campaigns. New York Daily News’ Chris Sommerfeldt wrote that candidates endorsing each other had become increasingly common and said “a candidate who trails after the first round of vote tabulations could eventually prevail if they are ranked on ballots featuring other candidates as the number one choice.”

Selma Bartholomew (D), Michael Blake (D), Paperboy Prince (D), and Whitney Tilson (D) also ran.
