Mamdani celebrates victory in 'reborn' New York City

Polls are now closed in New York City, where the mayoral race has garnered national attention.

With 15 minutes left until polls close, over 2 million New York City voters cast a ballot for this year's race, according to the city's Board of Elections.

This surpasses the 1.9 million votes cast in 1993 and 1989. The last time the tally surpassed 2 million votes was in 1969, according to the BOE.

A preliminary exit poll analysis by ABC News shed more light on the turnout in the New Jersey governor's race.

Over half of independents support Democrat Mikie Sherrill and she had the support of roughly 6 in 10 New Jersey female voters, according to preliminary exit poll data.

Roughly half of male voters in the state supported Republican Jack Ciatterelli, the preliminary analysis found.

A majority of New Jersey voters under 45 supported Sherrill according to early exit polling, while those 45 and older roughly split their votes roughly evenly between the Democratic and Republican candidates for governor, according to the data.

During her victory speech in the Virginia governor's race, Abigail Spanberger told the cheering crowd, "Tonight we sent a message."

The message to Virginia, the country and the world, she said, is that Virginia "chose pragmatism over partisanship."

"We chose our commonwealth over chaos," she said. "You all chose leadership that will focus relentlessly on what matters most -- lowering costs, keeping our communities safe and strengthening our economy for every Virginian."

She said she intends to serve all Virginians.

"I have worked with anyone and everyone, regardless of political party, to deliver results for the people that I serve, and that's because I believe in this idea that there is so much more that unites us as Virginians and as Americans than divides us," she said.
