Residents of the Big Apple will learn the identity of their new city leader this election day, in a race that will determine who governs and protects the nation's most populous metropolis at a moment when Donald Trump has vowed to deploy armed forces to the city.

Against that backdrop, New York has experienced a mayoral election that has pitted two distinctly opposing Democratic figures against each other. The election has turned into an acrimonious showdown, laced with alleged racial bias and anti-Muslim sentiment, but it is the ideological divide between the two leading contenders that could have major implications for how the party performs in next year's midterm elections.

The Rising Progressive

On the left side is the democratic socialist, the 34-year-old democratic socialist whose rapid ascent and grassroots campaign has brought international attention. Representing the old guard is the former governor, the former Democratic New York governor now running as an independent – and benefiting from the backing of ultra-rich donors and big business.

As the election approaches, it is Mamdani, the former longshot who defeated Cuomo in the Democratic primary who is firmly installed as the frontrunner. Mamdani, who has campaigned on a agenda of economic justice and pledged to halt rent increases for about two million New Yorkers, has led Cuomo by double-digits across all surveys conducted in the fall, and it is very much the progressive's election to lose.

A Bitter Contest

However, the former governor, who stepped down as the state's leader in recent years amid accusations of misconduct, has made it clear he will battle to the finish, and not necessarily in an above-the-belt fashion. He has trashed 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. Two weeks ago, Cuomo was strongly criticized as racist after sharing an AI-generated ad that included a series of racial caricatures and showed his opponent freeing a convicts.

This represents a particularly ugly end to an race that could be key to the direction that the Democratic party, struggling in its response to the former president's power moves, takes in the coming years.

Broader Consequences

If Mamdani secures a clear victory, the establishment party leaders who have declined to support his campaign will be forced to reckon with a message that has resonated with Americans' anger at inequality, inflation and the political elite. It would be hard for the Senate leader and Hakeem Jeffries not to embrace at least some of the candidate's progressive proposals about affordability, given the fresh face has created an enthusiasm within the party arguably not witnessed since Bernie Sanders campaigned for the White House in 2016.

However, should the former governor, who had been expected to sail to victory in the Democratic primary, achieve a remarkable riches-to-rags-to-riches victory, it could reinforce the party's existing approach of considered, uninspiring opposition – a tactic that has angered grassroots members. A New York rejection of Mamdani's optimistic platform could persuade party leaders that the wisest course is to stick to the political center – even as surveys show the current iteration of the Democratic party is widely disliked nationwide.

Voter Enthusiasm

Residents of the city appear to favor the Mamdani vision. Polls show that his backers are much more excited about their candidate than his opponent's supporters, something that has been apparent during the race. The candidate's engaging content on social media, his optimistic vision for New York and his readiness to actually venture out and meet people in the city has attracted an army of over fifty thousand supporters, many of them youth or first-time voters.

Negative Tactics

However, Cuomo, 67, continues to fight. And with the risks against him, the former governor has turned to negative campaigning in the final days.

Following extensive launching various attacks at his opponent to see what might resonate, the independent has concentrated on attacking Mamdani directly. He has called his rival, who was born in Uganda to Indian parents, an “extremist”, and appeared on Fox Business for an discussion with a rightwing host, where the candidate claimed New York “will not survive” his opponent as city leader. It hit bottom last week, when the former governor laughed along and said “that’s another problem” after a radio host said the candidate would “cheer” another 9/11-style attack.

Campaign Dynamics

The line of attack echoes much of what Trump, who has sent the military reserves to the capital and threatened to do the same to NYC, has said about the progressive, and maybe that shouldn’t come as a surprise. A set of wealthy residents, including some who contributed to the Republican in the 2024 election, have invested heavily into trying to get Cuomo elected, as other powerful voices have pressured Curtis Sliwa to withdraw from the race.

Candidate Backgrounds

For the his team, and his wealthy backers, are worried, it should never have come to this point. When Mamdani, one of one hundred fifty state legislators, launched his campaign for mayor in last year, few had known him, and in truth, few even paid attention.

The former governor, by comparison, eased his way into the contest in March 2025 and became the immediate frontrunner. He was the political heavyweight who apparently held every edge. The quintessential establishment figure, he had wed a political dynasty member and served in a Democratic presidency. He became New York governor in over a decade ago, 17 years after his father, Mario Cuomo, left office from the same position.

Mamdani, who was voted in to the state legislature in 2020, does not have the same political heritage. But his commitment to providing no-cost transit and free childcare – 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, Mamdani has faced some challenges in recent days, after video emerged suggesting him implying the New York police department and the IDF were connected.

“We have to make clear that when the boot of the NYPD is on your neck, it’s been influenced by the Israeli military,” Mamdani said in the recording, recorded at a Democratic Socialists of America gathering in 2023. The progressive, a longtime critic of the Israeli government who has said the country is committing genocide in the Palestinian territory, suggested he was questioning joint training exercises between the city police and Israeli forces.

Emotional Response

With the election nearing, the candidate seems to have gained empathy and backing, however, for his response to Cuomo’s increasing rhetoric.

Mamdani addressed Cuomo’s terrorism comments in an emotional video. In it, Mamdani remembered how, when he first campaigned for state assembly, a Muslim uncle advised to him that he did not have to disclose about his Muslim faith. It was a realization, Mamdani said, that many Muslim New Yorkers had been taught “again and again”: “That security could only be found in the shadows of our community. That it is in those shadows alone where Muslims could express their true selves, and that if we were to emerge from those seclusion, then it is in those silence that we must leave our faith.”

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