In his concession speech in the New York City mayoral race, former New York Gov. Andrew Cuomo said his campaign was the "right fight to wage."

"I am proud of what we did and what we did together," he said. "This campaign was to contest the philosophies that are shaping the Democratic Party, the future of this city and the future of this country."

He said it's notable that "almost half of New Yorkers did not vote to support a government agenda that makes promises that we know cannot be met."

He said his campaign was "a caution flag that we are heading down a dangerous, dangerous road. Well, we made that point, and they heard us, and we will hold them to it."

Cuomo thanked New York City Mayor Eric Adams for suspending his campaign "to make us more competitive," saying it was a "very gracious thing to do."

He also offered his congratulations to Zohran Mamdani, who is projected to win the mayoral race, which elicited boos from the crowd. Cuomo quickly chastised the reaction, saying, "That is not right, and that is not us."

The Democratic National Committee is arguing that tonight’s results are indicative that the youth vote is back on their side.

They argue that exit polling indicates they've "successfully won back" voters aged 18-29 while pointing to exit polls regarding young voters in the gubernatorial races in Virginia and New Jersey and the mayoral race in New York City.

Republican mayoral candidate Curtis Sliwa offered an emotional concession speech to supporters Tuesday night, stressing that the movement he built on the backs of the Guardian Angels, focused on creating a safer New York, will not be erased.

He also said his candidacy was proof that voters cannot be bought or bullied by the establishment, as he was pressured to drop out of the race to clear the field for independent Andrew Cuomo.

"This has always been us versus them. From the time I declared my candidacy, the masters of the of the universe, the billionaires decided that I should not have the right to represent all of you to be the voice of the voiceless, the working class people who the backbone of this city," said Sliwa. "You can't buy us, rent us. We are not for sale. We are the people."

Sliwa offered good luck to Zohran Mamdani, who is projected to win the mayoral election. Though he warned that if Mamdani tries to "implement socialism" or weaken police, Sliwa and his coalition will become the Mamdani administration's "worst nightmare."

After coming out on stage to New Jersey son Bruce Springsteen's "Born to Run," Mikie Sherrill made a promise of prosperity during her victory speech in the state's gubernatorial race.

"Liberty alone is not enough if the government makes it impossible for you to feed your family, to get a good education or to get a good job," she said. "So in this country, that shouldn't be too much to ask, but right now, all of it seems at risk. Governors have never mattered more, and in this state, I am determined to build prosperity for all of our citizens."

Sherrill said it was a "tough fight," and that she had just gotten a call from her opponent, Republican Jack Ciattarelli.

"I want to recognize him for stepping up," she said.
