New Yorkers will learn who will be their new city leader this election day, in a contest that will decide who governs and protects the country's largest city at a time when Donald Trump has vowed to deploy armed forces to the city.

Against that backdrop, New York has witnessed a race for mayor that has pitted two distinctly opposing Democrats against one another. The contest has become an increasingly bitter face-off, marked by accusations of racism and anti-Muslim sentiment, but it is the ideological divide between the two main 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 progressive candidate whose rapid ascent and grassroots campaign has brought global notice. Representing the old guard is Andrew Cuomo, the ex- New York governor now running as an independent – and enjoying the backing of wealthy contributors and big business.

With days to go, it is Mamdani, the one-time underdog who beat his opponent in the party primary who is solidly positioned as the frontrunner. The candidate, who has campaigned on a agenda of economic justice and pledged to halt rent increases for about 2 million New Yorkers, has led his rival by significant margins in every poll conducted in the fall, and it is very much the younger man's election to lose.

The Controversial Campaign

Yet, Cuomo, who resigned as the state's leader in recent years amid allegations of sexual harassment, has stated clearly he will battle to the finish, and not necessarily in an above-the-belt fashion. He has criticized his opponent's goals as unrealistic, and in recent days chuckled along as a broadcaster made Islamophobic remarks about Mamdani, who is a Muslim. Recently, Cuomo was widely condemned as bigoted after posting an artificial intelligence video that included a series of racial caricatures and showed his opponent freeing a convicts.

This represents a rather grubby conclusion to an race that could be key to the path that the Democratic party, floundering in its response to the former president's power moves, adopts in the near future.

National Implications

If the progressive secures a clear victory, the party establishment who have declined to support his bid will be compelled to address a platform that has resonated with voters' anger at inequality, 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 Democratic ranks arguably not witnessed since Bernie Sanders campaigned for the White House eight years ago.

However, should Cuomo, who had been predicted to sail to victory in the June primary, achieve a surprising riches-to-rags-to-riches win, it could cement the party's current model of cautious, uninspiring resistance – a strategy that has infuriated the party base. A New York defeat of Mamdani's optimistic platform could convince Schumer and Jeffries that the wisest course is to remain in the center – even as polls show the present version of the Democratic party is widely disliked across the country.

Campaign Energy

Voters in the city appear to favor the Mamdani vision. Polls show that his backers are much more excited about their candidate than Cuomo backers, something that has been apparent throughout the campaign. The candidate's snappy videos on social media, his hopeful outlook for the city and his readiness to actually get out and connect with voters in the city has drawn an army of over fifty thousand volunteers, many of them young or first-time voters.

Negative Tactics

However, Cuomo, 67, continues to fight. And with the stakes against him, the ex-leader has turned to negative campaigning in the final days.

After spending months launching various attacks at his opponent to see what might stick, the independent has concentrated on targeting Mamdani directly. He has labelled his rival, who was of Ugandan origin to Indian parents, an "radical", and appeared on Fox Business for an discussion with a rightwing host, where the candidate claimed the city “will not survive” Mamdani as mayor. It hit bottom recently, when the former governor laughed along and said “that’s another problem” after a radio host said Mamdani would “cheer” another 9/11-style attack.

Political Landscape

This strategy mirrors much of what Trump, who has sent the national guard to the capital and warned to do the same to NYC, has said about the progressive, and perhaps that shouldn’t come as a surprise. 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 into office, as other powerful voices have pressured the Republican candidate to drop out from the race.

Candidate Backgrounds

As far as the his team, and his billionaire supporters, are worried, it should not have reached to this point. When Mamdani, one of 150 state legislators, launched his campaign for mayor in October 2024, not many had known him, and in truth, few even paid attention.

Cuomo, by contrast, eased his way into the race in March 2025 and became the instant favorite. He was the big beast who seemingly held all the advantages. The classic establishment figure, he had wed a Kennedy and served in a Democratic presidency. He assumed office as the state's leader in 2011, seventeen years after his parent, Mario Cuomo, stepped down from the same position.

Mamdani, who was voted in to the New York state assembly in recently, does not have the comparable background. But his commitment to providing free buses and free childcare – along with the rent control promise – offer a brighter outlook of the future than Cuomo’s dire warnings about “mayhem” and rising criminal activity, and his promise to hire more police officers.

Recent Challenges

Nevertheless, the candidate has encountered difficulties in the final phase, after footage emerged appearing to show 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 throat, it’s been influenced by the IDF,” 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 country is committing genocide in Gaza, indicated he was criticizing joint training exercises between the NYPD and Israeli forces.

Emotional Response

As the race closes, Mamdani seems to have gained empathy and backing, however, for his reaction to his opponent's increasing rhetoric.

Mamdani responded to Cuomo’s 9/11 remarks in an emotional video. In it, the candidate recalled how, when he first ran for state assembly, a Muslim uncle advised to him that he did not have to disclose about his Muslim faith. It was a lesson, he said, that many Muslim New Yorkers 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 express their full identities, and that if we were to emerge from those shadows, then it is in those silence that we must leave our faith.”
