Residents of the Big Apple will find out the identity of their next mayor this election day, in a contest that will determine who governs and defends the country's most populous metropolis at a moment when Donald Trump has threatened to deploy armed forces to the city.

Against that backdrop, New York has witnessed a race for mayor that has pitted two very different Democratic figures against one another. The contest has turned into 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 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 meteoric rise and people-powered movement has brought global notice. Representing the old guard is the former governor, the ex- New York governor now campaigning independently – and enjoying the support of ultra-rich donors and corporations.

As the election approaches, it is Mamdani, the one-time underdog who beat his opponent in the Democratic primary who is solidly positioned as the frontrunner. The candidate, who has run on a agenda of economic justice and pledged to halt rent increases for about 2 million city residents, has led Cuomo by significant margins across all surveys taken in October, and it is very much the younger man's election to throw away.

The Controversial Campaign

However, Cuomo, who stepped down as the state's leader in 2021 amid allegations of sexual harassment, has stated clearly he will battle to the finish, and not necessarily in an fair manner. He has criticized Mamdani's goals as unrealistic, and in the final stretch laughed as a broadcaster made Islamophobic remarks about the candidate, who is Muslim. Recently, the independent was widely condemned as bigoted after sharing an AI-generated ad that included a slew of racist stereotypes and showed his opponent freeing a group of criminals.

It's been a particularly ugly conclusion to an race that could be critical to the path that the party, floundering in its response to Trump's power moves, adopts in the coming years.

Broader Consequences

Should Mamdani secures a clear victory, the establishment party leaders who have refused to endorse his campaign will be forced to reckon with a message that has appealed to voters' frustration at inequality, inflation and the political elite. It would be difficult for Chuck Schumer and Hakeem Jeffries not to embrace at least a portion of the candidate's ambitious ideas about economic justice, given the newcomer has created an excitement within the party arguably not witnessed since the Vermont senator campaigned for the White House eight years ago.

However, if Cuomo, who had been expected to sail to victory in the June primary, achieve a remarkable comeback win, it could cement the party's existing approach of cautious, uninspiring resistance – a strategy that has angered the party base. A New York defeat of Mamdani's progressive, positive message could persuade Schumer and Jeffries that the best plan is to stick to the center – even as surveys show the current iteration of the Democratic party is widely disliked nationwide.

Voter Enthusiasm

Voters in New York seem to prefer the progressive agenda. Surveys show that Mamdani supporters are far more enthusiastic about their candidate than Cuomo backers, something that has been apparent during the race. Mamdani's snappy videos on social media, his optimistic vision for the city and his willingness to actually get out and meet people in the metropolis has attracted an army of over fifty thousand volunteers, many of them young or new participants.

Personal Attacks

Yet, the former governor, 67, continues to fight. And with the stakes stacked against him, the ex-leader has resorted to negative campaigning in the final days.

Following extensive launching various attacks at Mamdani to see what might resonate, Cuomo has narrowed his focus on targeting the candidate personally. He has called his rival, who was born in Uganda to Indian parents, an “extremist”, and appeared on Fox Business for an discussion with Maria Bartiromo, where the candidate claimed the city “will not survive” his opponent as city leader. It reached a nadir recently, when the former governor chuckled and said “that’s another problem” after a radio host said Mamdani would “cheer” another terrorist attack.

Political Landscape

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 New York, has said about the progressive, and perhaps 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 urged the Republican candidate to drop out from the contest.

Candidate Backgrounds

For the his team, and his wealthy backers, are concerned, it should never have come to this. When the assemblyman, one of 150 New York state assembly members, launched his mayoral bid in October 2024, not many had heard of him, and in truth, barely anyone even paid attention.

Cuomo, by contrast, entered smoothly into the contest in March 2025 and became the immediate frontrunner. He was the political heavyweight who seemingly held every edge. The quintessential establishment figure, he had wed a political dynasty member and served in a Democratic presidency. He became the state's leader in 2011, 17 years after his parent, Mario Cuomo, stepped down from the identical role.

Mamdani, who was voted in to the state legislature in 2020, does not have the comparable background. But his commitment to providing no-cost transit and free childcare – along with the rent control promise – present a more positive vision of the future than Cuomo’s pessimistic predictions about “mayhem” and rising criminal activity, and his vow to increase police presence.

Recent Challenges

Still, Mamdani has encountered difficulties in recent days, after video surfaced suggesting him suggesting the NYPD and the IDF were connected.

“We have to make clear that when the pressure of the NYPD is on your throat, it’s been laced by the Israeli military,” the candidate said in the clip, filmed at a DSA convention in recent years. The progressive, a vocal opponent of Israel who has said the country is committing genocide in Gaza, indicated he was questioning cooperative programs between the city police and Israeli forces.

Emotional Response

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

The progressive responded to Cuomo’s 9/11 remarks in an heartfelt recording. In it, Mamdani recalled how, when he first campaigned for state assembly, a Muslim uncle suggested to him that he did not have to tell people about his religion. It was a lesson, he said, that many local Muslims had been taught “again and again”: “That security could only be found in the margins of our community. 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 shadows, then it is in those shadows that we must set aside our faith.”

Speaking to the behavior of Cuomo and Sliwa, who has claimed Mamd
