Residents of the Big Apple will learn the identity of their new city leader this Tuesday, in a race that will decide who governs and protects the country's largest city at a moment when the former president has threatened to send armed forces to the city.

Against that backdrop, New York has experienced a mayoral election that has pitted two distinctly opposing Democrats against one another. The election has turned into an increasingly bitter face-off, laced with alleged racial bias and Islamophobia, but it is the ideological divide between the two leading candidates that could have significant consequences for how the party performs in next year's congressional races.

The Progressive Challenger

In the progressive corner is Zohran Mamdani, the young democratic socialist whose meteoric rise and people-powered movement has attracted global notice. Representing the old guard is the former governor, the ex- New York governor now campaigning independently – and enjoying 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 solidly positioned as the leading candidate. The candidate, who has run on a agenda of economic justice and promised to freeze rent for about 2 million city residents, has led his rival by double-digits across all surveys taken in the fall, and it is very much the progressive's election to lose.

The Controversial Campaign

However, the former governor, who stepped down as governor in recent years amid allegations of misconduct, has made it clear he will fight to the end, and not necessarily in an fair fashion. He has trashed Mamdani's goals as unrealistic, and in recent days chuckled along as a broadcaster made anti-Muslim comments about Mamdani, who is Muslim. Recently, Cuomo was widely condemned as racist after posting an AI-generated ad that included a series of racist stereotypes and showed his opponent freeing a convicts.

This represents a particularly ugly end to an race that could be critical to the path that the Democratic party, floundering in its reaction to the former president's authoritarian grabs, takes in the near future.

Broader Consequences

Should Mamdani secures a clear victory, the party establishment who have refused to endorse his campaign will be forced to reckon with a platform that has appealed to Americans' frustration at inequality, soaring price rises and the political elite. It would be hard for Chuck Schumer and Hakeem Jeffries not to adopt at least some of the candidate's ambitious ideas about affordability, given the newcomer has created an enthusiasm within the Democratic ranks arguably not seen since Bernie Sanders ran for president eight years ago.

However, should Cuomo, who had been predicted to win easily in the June primary, achieve a remarkable riches-to-rags-to-riches win, it could reinforce the party's existing approach of cautious, lackluster opposition – a tactic that has infuriated grassroots members. A New York defeat of Mamdani's progressive, positive message could convince Schumer and Jeffries that the wisest course is to stick to the center – even as polls show the present version of the party is deeply unpopular nationwide.

Campaign Energy

Residents of New York seem to prefer the progressive agenda. Surveys show that his backers are much more excited about their choice than Cuomo backers, something that has been apparent throughout the campaign. Mamdani's engaging content on social media, his hopeful outlook for the city and his willingness to actually venture out and connect with voters in the city has drawn an army of over fifty thousand supporters, many of them youth or new participants.

Personal Attacks

However, Cuomo, 67, isn't giving up. And with the risks against him, the ex-leader has turned to ugly messaging in recent weeks.

After spending months launching various attacks at his opponent to see what might resonate, the independent has concentrated on attacking Mamdani personally. He has labelled his rival, who was born in Uganda to South Asian heritage, an “extremist”, and appeared on Fox Business for an discussion with a rightwing host, where the candidate asserted the city “will not survive” Mamdani as city leader. It hit bottom last week, when Cuomo laughed along and said “that’s another problem” after a radio host said Mamdani would “cheer” another 9/11-style attack.

Campaign Dynamics

The line of attack mirrors much of what Trump, who has deployed the national guard to Washington DC and warned to take similar action to New York, has said about the progressive, and maybe that is expected. A group of billionaire New Yorkers, including some who contributed to the Republican in the last presidential race, have invested heavily into trying to elect Cuomo into office, as other powerful voices have pressured the Republican candidate to withdraw from the contest.

Candidate Backgrounds

For the Cuomo camp, and his wealthy backers, are concerned, it should never have come to this. When Mamdani, one of one hundred fifty state legislators, launched his campaign for mayor in last year, not many had heard of him, and in reality, barely anyone even paid attention.

Cuomo, by contrast, entered smoothly into the contest in March 2025 and became the instant favorite. He was the big beast who seemingly held every edge. The quintessential 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 father, the former governor, stepped down from the identical role.

The progressive, who was voted in 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 rent control promise – offer a more positive vision of the city's direction than Cuomo’s dire warnings about “mayhem” and unfettered crime, and his vow to increase police presence.

Recent Challenges

Still, the candidate has faced difficulties in the final phase, after footage emerged appearing to show him implying the New York police department and the Israel Defense Forces were connected.

“We have to make clear that when the boot of the police is on your throat, it’s been influenced by the IDF,” Mamdani said in the clip, recorded at a Democratic Socialists of America convention in recent years. The progressive, a vocal opponent 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 NYPD and Israeli forces.

Emotional Response

As the race closes, the candidate seems to have gained empathy and backing, however, for his reaction to his opponent's escalating attacks.

The progressive responded to Cuomo’s 9/11 remarks in an emotional video. In it, Mamdani recalled how, when he first campaigned 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 local Muslims had been told “again and again”: “That safety could only be found in the margins of our community. That it is in those hidden spaces alone where followers of Islam could embrace their full identities, and that if we were to step out from those seclusion, then it is in those shadows that we must leave our faith.”
