Residents of the Big Apple will discover the identity of their next mayor this election day, in a contest that will decide who runs and protects the country's most populous metropolis at a moment when the former president has threatened to send military troops to the city.

In this context, New York has experienced a race for mayor that has pitted two very different Democrats against each other. The election has turned into an acrimonious face-off, laced with accusations of racial bias and anti-Muslim sentiment, but it is the political differences between the two leading candidates that could have major implications for how the Democratic party performs in next year's congressional races.

The Progressive Challenger

On the left side is the democratic socialist, the young progressive candidate whose rapid ascent and grassroots campaign has brought global notice. On the establishment side is the former governor, the former Democratic New York governor now campaigning independently – and enjoying the backing of ultra-rich donors and corporations.

With days to go, it is Mamdani, the former longshot who beat Cuomo in the party primary who is solidly positioned as the leading candidate. Mamdani, who has campaigned on a platform of affordability and pledged to freeze rent for about two million New Yorkers, has led his rival by double-digits across all surveys taken in the fall, and it is very much the progressive's race to throw away.

A Bitter Contest

However, Cuomo, who stepped down as the state's leader in recent years amid allegations of misconduct, has made it clear he will battle to the finish, and not necessarily in an fair manner. He has criticized his opponent's goals as unachievable, and in recent days chuckled along as a radio host made anti-Muslim comments about Mamdani, who is a Muslim. Recently, Cuomo was strongly criticized as racist after sharing an artificial intelligence video that included a series of racist stereotypes and showed his opponent releasing a convicts.

This represents a rather grubby conclusion to an race that could be key to the path that the party, struggling in its reaction to the former president's power moves, takes in the near future.

National Implications

Should the progressive wins convincingly, the party establishment who have declined to support his bid will be forced to reckon with a message that has resonated with voters' frustration at economic disparity, soaring price rises and the political elite. It would be difficult for the Senate leader and Hakeem Jeffries not to adopt at least a portion of Mamdani's progressive proposals about affordability, given the newcomer has generated an excitement within the Democratic ranks perhaps not seen since the Vermont senator campaigned for the White House eight years ago.

However, should the former governor, who had been predicted to win easily in the June primary, complete a surprising riches-to-rags-to-riches victory, it could reinforce national Democrats' existing approach of cautious, lackluster resistance – a strategy that has angered grassroots members. A New York defeat of Mamdani's optimistic platform could convince party leaders that the best plan is to remain in the political center – even as polls show the current iteration of the party is widely disliked nationwide.

Campaign Energy

Voters in New York seem to prefer the progressive agenda. Polls show that his backers are much more excited about their candidate than Cuomo backers, something that has been evident throughout the campaign. The candidate's engaging content on social media, his optimistic vision for New York and his readiness to actually get out and connect with voters in the metropolis has drawn an force of more than 50,000 supporters, many of them youth or first-time voters.

Personal Attacks

However, the former governor, in his late sixties, continues to fight. And with the risks stacked against him, the ex-leader has turned to ugly messaging in recent weeks.

Following extensive launching various attacks at his opponent to see what might stick, Cuomo has narrowed his focus on targeting the candidate directly. He has labelled Mamdani, who was born in Uganda to South Asian heritage, an "radical", and appeared on Fox Business for an interview with a rightwing host, where the candidate claimed New York “will not survive” Mamdani as mayor. It reached a nadir recently, when Cuomo chuckled and said “that’s another problem” after a radio host said Mamdani would “cheer” another terrorist incident.

Campaign Dynamics

The line of attack echoes much of what Trump, who has sent the military reserves to the capital and threatened to take similar action to NYC, has said about the progressive, and perhaps that shouldn’t come as a surprise. A set of wealthy residents, including some who contributed to Trump in the last presidential race, have pumped millions into trying to elect the independent elected, as other influential figures have pressured Curtis Sliwa to withdraw from the race.

Political Histories

For the his team, and his billionaire supporters, are concerned, it should not have reached to this point. When Mamdani, one of 150 New York state assembly members, launched his campaign for mayor in last year, few had heard of him, and in truth, few even noticed.

The former governor, by comparison, eased his way into the race in March 2025 and became the instant favorite. He was the big beast who seemingly held all the advantages. The classic establishment figure, he had married a political dynasty member and served in a Democratic presidency. He became New York governor in over a decade ago, 17 years after his parent, the former governor, stepped down from the identical role.

The progressive, who was voted in to the New York state assembly in 2020, does not have the same political heritage. But his commitment to providing free buses and affordable child services – along with the freeze-the-rent pledge – present a more positive vision of the future than Cuomo’s pessimistic predictions about “mayhem” and unfettered crime, and his promise to hire more police officers.

Campaign Controversies

Still, the candidate has encountered some challenges in the final phase, after video surfaced suggesting him suggesting the New York police department and the IDF were intertwined.

“We have to make clear that when the boot of the NYPD is on your neck, it’s been laced by the Israeli military,” Mamdani said in the recording, filmed at a Democratic Socialists of America gathering in recent years. Mamdani, a vocal opponent of the Israeli government who has said the country is engaging in atrocities in Gaza, suggested he was criticizing joint training exercises between the city police and Israeli forces.

Emotional Response

With the election nearing, the candidate seems to have gained sympathy and support, however, for his reaction to his opponent's increasing rhetoric.

Mamdani responded to Cuomo’s 9/11 remarks in an emotional video. In it, Mamdani recalled how, when he first ran for the legislature, a family member suggested to him that he did not have to tell people about his religion. It was a realization, Mamdani said, that many local Muslims had been told “again and again”: “That security could only be found in the shadows of our city. That it is in those hidden spaces alone where Muslims could embrace their full identities, and that if we were to step out from those seclusion, then it is in those shadows that we must set aside our beliefs.”

Addressing the behavior of Cuomo and Sliwa, who has claimed Mamd
