Residents of the Big Apple will learn the identity of their new city leader this election day, in a contest that will determine who runs and protects the country's largest city at a moment when Donald Trump has threatened to send military troops to the urban center.

Against that backdrop, New York has experienced a mayoral election that has pitted two very different Democratic figures against one another. The election has turned into an acrimonious showdown, marked by accusations of racism and Islamophobia, but it is the ideological divide between the two main candidates that could have major implications for how the Democratic party performs in next year's congressional races.

The Rising Progressive

In the progressive corner is the democratic socialist, the 34-year-old progressive candidate whose meteoric rise and grassroots campaign has attracted global notice. Representing the old guard is Andrew Cuomo, the former Democratic New York governor now running as an independent – and benefiting from the support of wealthy contributors and corporations.

With days to go, it is the progressive, the one-time underdog who beat Cuomo in the party primary who is firmly installed as the frontrunner. Mamdani, who has run on a platform of economic justice and pledged to freeze rent for about 2 million city residents, has outpaced his rival by significant margins across all surveys taken in October, and it is very much the progressive's election to throw away.

A Bitter Contest

Yet, Cuomo, who resigned as governor 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 Mamdani's goals as unrealistic, and in recent days laughed as a radio host made Islamophobic remarks about the candidate, who is Muslim. Two weeks ago, Cuomo was widely condemned as racist after posting an AI-generated ad that included a series of racial caricatures and showed Mamdani freeing a convicts.

This represents a particularly ugly conclusion to an election that could be critical to the direction that the Democratic party, floundering in its response to Trump's power moves, adopts in the near future.

National Implications

If Mamdani secures a clear victory, the establishment party leaders who have refused to endorse his bid will be forced to reckon with a message that has resonated with Americans' anger at economic disparity, inflation and the establishment. It would be hard for the Senate leader and Hakeem Jeffries not to embrace at least a portion of the candidate's progressive proposals about affordability, given the fresh face has generated an enthusiasm within the party perhaps not witnessed since the Vermont senator ran for president in 2016.

However, if Cuomo, who had been predicted to sail to victory in the Democratic primary, achieve a surprising riches-to-rags-to-riches win, it could reinforce national Democrats' current model of cautious, lackluster resistance – a tactic that has infuriated the party base. A New York rejection of Mamdani's progressive, positive message could persuade party leaders that the best plan is to remain in the political center – even as surveys show the current iteration of the Democratic party is widely disliked across the country.

Campaign Energy

Residents of New York seem to prefer the progressive agenda. Surveys show that his backers are much more excited about their candidate than Cuomo backers, something that has been apparent during the race. Mamdani's engaging content 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 army of more than 50,000 volunteers, many of them youth or first-time voters.

Negative Tactics

Yet, Cuomo, 67, isn't giving up. And with the stakes against him, the ex-leader has resorted to negative campaigning in recent weeks.

Following extensive launching various attacks at Mamdani to see what might stick, Cuomo has concentrated on targeting the candidate personally. He has called Mamdani, who was of Ugandan origin to Indian parents, an "radical", and appeared on conservative media for an interview with a rightwing host, where Cuomo asserted the city “will not survive” his opponent as mayor. It hit bottom last week, when the former governor chuckled and said “that’s another problem” after a broadcaster said the candidate would “cheer” another 9/11-style incident.

Campaign Dynamics

The line of attack echoes much of what Trump, who has deployed the military reserves to Washington DC and warned to do the same to NYC, has said about Mamdani, and perhaps that is expected. A set of wealthy residents, including some who donated to the Republican in the 2024 election, have pumped millions into trying to elect Cuomo into office, as other powerful voices have urged Curtis Sliwa to withdraw from the contest.

Candidate Backgrounds

For the his team, and his billionaire supporters, are concerned, it should not have reached to this point. When Mamdani, one of one hundred fifty New York state assembly members, launched his mayoral bid in October 2024, not many had heard of him, and in reality, barely anyone even paid attention.

The former governor, by contrast, entered smoothly into the contest in March 2025 and became the instant favorite. He was the political heavyweight who seemingly held every edge. The classic establishment figure, he had married a Kennedy and worked in Bill Clinton’s administration. He assumed office as New York governor in over a decade ago, 17 years after his father, the former governor, stepped down from the same position.

The progressive, who was voted in to the New York state assembly in 2020, does not have the comparable background. But his commitment to providing free buses and affordable child services – along with the rent control promise – offer a brighter outlook of the city's direction than his opponent's pessimistic predictions about “mayhem” and unfettered crime, and his promise to hire more police officers.

Recent Challenges

Still, the candidate has faced some challenges in recent days, after video emerged suggesting him suggesting the New York police department and the Israel Defense Forces were intertwined.

“We have to make clear that when the pressure of the police is on your neck, it’s been influenced by the Israeli military,” the candidate said in the clip, recorded at a Democratic Socialists of America convention in recent years. The progressive, a vocal opponent of Israel who has said the nation is engaging in atrocities in the Palestinian territory, suggested he was questioning cooperative programs between the city police and Israeli forces.

Emotional Response

As the race closes, the candidate seems to have gained sympathy and support, however, for his response to Cuomo’s escalating attacks.

Mamdani addressed the independent's terrorism comments in an heartfelt recording. In it, Mamdani recalled how, when he first ran for state assembly, a Muslim uncle suggested to him that he did not have to disclose about his Muslim faith. It was a realization, Mamdani said, that many local Muslims had been taught “again and again”: “That safety could only be found in the shadows of our city. That it is in those hidden spaces alone where followers of Islam could express their true selves, and that if we were to emerge from those shadows, then it is in those silence that we must set aside our beliefs.”
