New York City voters head to the polls on the first day of early voting — with a stunning five-fold increase until the latest mayoral race.

Nearly 80,000 Big Apple voters turned out to cast ballots as early voting began Saturday — a number nearly five times higher than early voter turnout in 2021, according to unofficial data.

The New York City Board of Elections reported a total of 79,409 early voter registrations as polls closed on Saturday — a sharp jump from the 15,418 who showed up when early voting began four years ago.

This increase comes in light of a highly competitive race to succeed Mayor Eric Adams between former Governor Andrew Cuomo, who is running as an independent candidate against the Democratic Socialist Party, Zahran Mamdani, and Republican Curtis Saliwa.

Officials said 24,046 votes were cast in Manhattan, 7,793 in the Bronx, 22,105 in Brooklyn, 19,045 in Queens and 6,420 on State Island.

This was significantly more than the first day numbers for 2021, which saw 4,563 voters in Manhattan, 2,079 voters in the Bronx, 3,751 voters in Brooklyn, 3,441 voters in Queens, and 1,584 voters in Staten Island.

The increase was touted by Cuomo’s longtime top aide Melissa DeRosa, who said on X: “If these numbers continue, we could see a turnout of 1.9 million people.”

Mamdani is now leading in the polls by double digits to win the job overseeing the city’s $115 billion budget and workforce of about 300,000 people.

Adams, a centrist Democrat, suspended his faltering re-election campaign last month as fundraising delayed after a federal investigation, despite being cleared of corruption allegations.
