Residents of the Big Apple will learn who will be their next mayor this election day, in a race that will determine who runs and defends the country's largest city at a time when Donald Trump has vowed to deploy military troops to the urban center.

Against that backdrop, New York has witnessed a race for mayor that has pitted two very different Democrats against each other. The contest has become an increasingly bitter showdown, marked by accusations of racism and anti-Muslim sentiment, but it is the ideological divide between the two leading candidates that could have significant consequences for how the party performs in next year's congressional races.

The Progressive Challenger

On the left side is Zohran Mamdani, the 34-year-old progressive candidate whose rapid ascent and people-powered movement has attracted international attention. On the establishment side is the former governor, the ex- Democratic New York governor now campaigning independently – and benefiting from the backing of wealthy contributors and corporations.

As the election approaches, it is Mamdani, the former longshot who defeated his opponent in the Democratic primary who is firmly installed as the frontrunner. Mamdani, who has campaigned on a agenda of economic justice and promised to halt rent increases for about two million New Yorkers, has led his rival by significant margins in every poll conducted in October, and it is very much the younger man's election to lose.

The Controversial Campaign

However, the former governor, who stepped down as the state's leader in 2021 amid accusations of sexual harassment, has made it clear he will fight to the finish, and not necessarily in an fair manner. He has criticized his opponent's goals as unrealistic, and in recent days chuckled along as a radio host made anti-Muslim comments about Mamdani, who is a Muslim. Recently, the independent was strongly criticized as racist after posting an AI-generated ad that featured a series of racial caricatures and showed Mamdani releasing a convicts.

This represents a rather grubby end to an election that could be critical to the direction that the party, floundering in its reaction to Trump's power moves, takes in the coming years.

Broader Consequences

Should Mamdani secures a clear victory, the establishment party leaders who have declined to support his campaign will be forced to reckon with a platform that has appealed to Americans' frustration at inequality, inflation and the establishment. It would be hard for the Senate leader and the House leader not to embrace at least some of the candidate's ambitious ideas about economic justice, given the fresh face has created an excitement within the Democratic ranks perhaps not seen since the Vermont senator ran for president eight years ago.

Conversely, if Cuomo, who had been expected to sail to victory in the June primary, achieve a surprising comeback win, it could cement national Democrats' existing approach of considered, uninspiring opposition – a strategy that has angered grassroots members. A New York rejection of the progressive's optimistic platform could convince Schumer and Jeffries that the best plan is to remain in the political center – even as polls show the current iteration of the party is widely disliked across the country.

Campaign Energy

Residents of New York appear to favor the progressive agenda. Surveys show that his backers are much more excited about their choice than his opponent's supporters, something that has been evident throughout the campaign. The candidate's snappy videos on digital platforms, his optimistic vision for the city and his readiness to actually venture out and connect with voters in the city has attracted an force of more than 50,000 supporters, many of them youth or first-time voters.

Personal Attacks

Yet, the former governor, in his late sixties, continues to fight. And with the risks stacked against him, the ex-leader has turned to negative campaigning in the final days.

After spending months launching various attacks at Mamdani to see what might resonate, the independent has concentrated on attacking Mamdani personally. He has labelled his rival, who was of Ugandan origin to Indian parents, an "radical", and popped up on conservative media for an discussion with a rightwing host, where Cuomo asserted the city “will not survive” his opponent as city leader. It reached a nadir recently, when Cuomo chuckled and said “that’s another problem” after a broadcaster said Mamdani would “cheer” another 9/11-style attack.

Campaign Dynamics

This strategy echoes much of what the former president, who has deployed the national guard to the capital and warned to take similar action to NYC, has said about the progressive, and maybe that is expected. A set of wealthy residents, including some who contributed to the Republican in the last presidential race, have pumped millions into trying to get the independent elected, as other powerful voices have pressured the Republican candidate to withdraw from the race.

Candidate Backgrounds

As far as the Cuomo camp, and his wealthy backers, are worried, it should never have come to this point. When Mamdani, one of one hundred fifty state legislators, started his mayoral bid in October 2024, few had known him, and in reality, few even noticed.

Cuomo, by contrast, entered smoothly into the race in March 2025 and became the instant favorite. He was the political heavyweight who seemingly held all the advantages. The classic establishment figure, he had wed a political dynasty member and worked in Bill Clinton’s administration. He became New York governor in over a decade ago, 17 years after his parent, Mario Cuomo, left office from the same position.

The progressive, who was voted in to the New York state assembly in recently, does not have the comparable background. But his dedication to providing no-cost transit and affordable child services – along with the rent control promise – present a brighter outlook of the future than his opponent's dire warnings about “mayhem” and unfettered crime, and his promise to hire more police officers.

Campaign Controversies

Still, Mamdani has faced some challenges in the final phase, after footage surfaced appearing to show him suggesting the New York police department and the Israel Defense Forces were connected.

“We have to make clear that when the pressure of the NYPD is on your throat, it’s been laced by the IDF,” Mamdani said in the recording, filmed at a DSA gathering in recent years. Mamdani, a vocal opponent of the Israeli government who has said the nation is committing genocide in the Palestinian territory, indicated he was questioning joint training exercises between the NYPD and Israeli forces.

Emotional Response

As the race closes, the candidate appears to have won empathy and backing, however, for his response to Cuomo’s increasing rhetoric.

The progressive responded to the independent's terrorism comments in an emotional video. In it, the candidate recalled how, when he first campaigned for the legislature, a family member advised to him that he did not have to tell people about his Muslim faith. It was a realization, Mamdani said, that many Muslim New Yorkers had been told “again and again”: “That security could only be found in the margins of our city. That it is in those shadows alone where Muslims could express their full identities, and that if we were to emerge from those seclusion, then it is in those silence that we must leave our faith.”
