Mamdani celebrates victory in 'reborn' New York City

Vice President JD Vance urged voters in New Jersey to cast their vote for Republican gubernatorial candidate Jack Ciattarelli, as the race tightens between Ciattarelli and the Democrats' pick, former Navy helicopter pilot Mikie Sherrill.

"Get out there and vote for Jack if you live in NJ. New Jersey is such a great state but it's suffered too long under crap leadership," Vance wrote on Tuesday.

According to a Quinnipiac poll, Ciattarelli is lagging Sherill only by single digits in the race, with Sherill leading Ciatttarelli by 8 points in the full ballot matchup.

Former President Barack Obama has previously endorsed Sherill, saying her "integrity, grit and commitment to service are what we need right now in our leaders."

In addition to being backed by Vance, Ciattarelli also boasts the support of President Donald Trump.

While New Yorkers are focused on solving key issues of affordability and public safety, the implications of the mayoral race could stretch beyond the five boroughs.

This local off-year election has garnered national attention and is considered representative of political headwinds ahead of the 2026 midterms. Candidates are zeroed in on navigating the impacts of President Donald Trump's second term, and Zohran Mamdani's candidacy has shed light on how the Democratic Party has struggled to balance its progressive and moderate sides.

Former New York Gov. Andrew Cuomo, who appeared to cast his ballot at a polling place on the East Side of Manhattan on Tuesday morning, called President Donald Trump "pragmatic" for encouraging Republican voters to support him in the New York City mayoral election, instead of the GOP nominee, Guardian Angels founder Curtis Sliwa, to blunt a victory for Democratic nominee Zohran Mamdani.

"President Trump is pragmatic. He is telling them the reality of the situation, which is, if you do not vote, Mamdani is going to win. Who is Mamdani? I don't know, but he's a Democratic socialist that brings socialism to New York City. New York City will not thrive with a socialist economy," Cuomo, who is running as an independent, said on Fox News on Tuesday. "So Republicans, you have to get up and come out and vote. Even if you're not voting for a Republican, you're voting to save New York City."

Cuomo went on to say that Mamdani's campaign promises to lower costs and expand government resources -- by freezing the rent temporarily on rent stabilized units, providing government-run grocery stores and free city busses -- is "all BS."

"It's not up to the mayor. It's up to the state. State said they're not going to do it. It's all BS, it's all campaign rhetoric. None of it will change anybody's life," Cuomo argued.

Accompanied by her husband and children, New Jersey's Democratic nominee for governor Mikie Sherrill appeared at a Montclair voting center to cast her ballot and address the press.

Sherrill sought to assure voters that it is currently safe to cast ballots throughout the state, after multiple polling places temporarily closed in northern New Jersey after precincts fielded emailed bomb threats later deemed to be not credible, prompting election officials to direct some voters to other polling places.

"We’ve checked out all the bomb threats. There are no credible ones yet. Law enforcement is working overtime to keep our elections safe, so I don't see any threat to voting," Sherrill said. She called the scare an "attempt to suppress the vote."
