Residents of the Big Apple will find out the identity of their new city leader this election day, in a race that will decide who runs and protects the country's largest city at a moment when Donald Trump has vowed to deploy armed forces to the city.

In this context, New York has experienced a race for mayor that has pitted two distinctly opposing Democrats against one another. The contest has become an acrimonious showdown, laced with alleged racism and anti-Muslim sentiment, but it is the political differences between the two leading contenders that could have significant consequences for how the Democratic party performs in next year's congressional races.

The Rising Progressive

On the left side is the democratic socialist, the young progressive candidate whose rapid ascent and grassroots campaign has attracted international attention. Representing the old guard is Andrew Cuomo, the ex- Democratic New York governor now campaigning independently – and enjoying the support of ultra-rich donors and big business.

As the election approaches, it is Mamdani, the one-time underdog 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 pledged to freeze rent for about 2 million New Yorkers, has led Cuomo by double-digits across all surveys conducted in the fall, and it is very much the younger man's election to throw away.

A Bitter Contest

Yet, Cuomo, who stepped down as governor in 2021 amid accusations of misconduct, has stated clearly he will fight to the end, and not necessarily in an fair manner. He has trashed Mamdani's goals as unachievable, and in recent days laughed as a broadcaster made anti-Muslim comments about the candidate, who is a Muslim. Two weeks ago, the independent was strongly criticized as racist after posting an AI-generated ad that included a slew of racist stereotypes and showed Mamdani freeing a convicts.

It's been a particularly ugly conclusion to an race that could be critical to the direction that the party, struggling in its response to Trump's authoritarian grabs, adopts in the coming years.

National Implications

If Mamdani wins convincingly, the party establishment who have refused to endorse his bid will be compelled to address a message that has resonated with voters' anger at economic disparity, soaring price rises and the political elite. It would be hard for Chuck Schumer and Hakeem Jeffries not to adopt at least a portion of the candidate's progressive proposals about economic justice, given the newcomer has generated an excitement within the party perhaps not witnessed since Bernie Sanders campaigned for the White House eight years ago.

Conversely, if Cuomo, who had been expected to sail to victory in the Democratic primary, achieve a remarkable riches-to-rags-to-riches victory, it could reinforce national Democrats' existing approach of considered, lackluster opposition – a tactic that has infuriated the party base. A NYC defeat of Mamdani's optimistic platform could persuade Schumer and Jeffries that the best plan is to remain in the center – even as surveys show the current iteration of the party is deeply unpopular nationwide.

Voter Enthusiasm

Residents of New York seem to prefer the Mamdani vision. Surveys show that his backers are far more enthusiastic about their choice than his opponent's supporters, something that has been evident during the race. The candidate's snappy videos on digital platforms, his optimistic vision for New York and his willingness to actually get out and connect with voters in the city has drawn an army of more than 50,000 volunteers, many of them young or new participants.

Personal Attacks

However, Cuomo, in his late sixties, isn't giving up. And with the risks against him, the former governor has turned to ugly messaging in recent weeks.

After spending months throwing basically everything at his opponent to see what might stick, Cuomo has narrowed his focus on targeting Mamdani directly. He has labelled Mamdani, who was born in Uganda to Indian parents, an “extremist”, and popped up on conservative media for an discussion with Maria Bartiromo, where Cuomo asserted the city “will not survive” his opponent as mayor. It reached a nadir last week, when Cuomo chuckled and said “that’s another problem” after a broadcaster said the candidate would “cheer” another 9/11-style incident.

Political Landscape

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 Mamdani, and perhaps that shouldn’t come as a surprise. A group of wealthy residents, including some who contributed to Trump in the last presidential race, have pumped millions into trying to get Cuomo elected, as other powerful voices have urged the Republican candidate to withdraw from the contest.

Political Histories

As far as the his team, and his billionaire supporters, are worried, it should never have come to this. When the assemblyman, one of one hundred fifty New York state assembly members, started his campaign for mayor in October 2024, not many had known him, and in reality, few even noticed.

Cuomo, by comparison, entered smoothly into the race in March 2025 and became the immediate frontrunner. He was the big beast who apparently held all the advantages. The classic establishment figure, he had wed a Kennedy and served in a Democratic presidency. He assumed office as New York governor in over a decade ago, seventeen years after his parent, Mario Cuomo, left office from the same position.

The progressive, who was elected to the New York state assembly in 2020, does not have the comparable background. But his dedication to providing no-cost transit and free childcare – along with the freeze-the-rent pledge – present a more positive vision of the city's direction than Cuomo’s pessimistic predictions about “mayhem” and rising criminal activity, and his vow to hire more police officers.

Recent Challenges

Still, Mamdani has encountered some challenges in the final phase, after footage emerged suggesting him suggesting the New York police department and the Israel Defense Forces were intertwined.

“We have to make clear that when the boot of the NYPD is on your neck, it’s been influenced by the IDF,” Mamdani said in the recording, recorded at a DSA gathering in 2023. The progressive, a vocal opponent of the Israeli government who has said the nation is engaging in atrocities in the Palestinian territory, suggested he was criticizing joint training exercises between the city police and Israeli forces.

Powerful Moment

With the election nearing, Mamdani appears to have won sympathy and support, however, for his reaction to Cuomo’s escalating attacks.

Mamdani addressed the independent's 9/11 remarks in an emotional video. In it, Mamdani recalled how, when he first ran for the legislature, a Muslim uncle suggested 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 safety could only be found in the margins of our city. That it is in those shadows alone where Muslims could embrace their true selves, and that if we were to emerge from those seclusion, then it is in those shadows that we must set aside our faith.”
