Residents of the Big Apple will find out the identity of their next mayor this Tuesday, in a contest that will determine who runs and defends the country's most populous metropolis at a time when Donald Trump has vowed to deploy armed forces to the urban center.

Against that backdrop, New York has witnessed a race for mayor that has pitted two very different Democratic figures against one another. The election has turned into an increasingly bitter showdown, marked by alleged racial bias and Islamophobia, but it is the ideological divide between the two leading candidates that could have major implications for how the party performs in next year's congressional races.

The Rising Progressive

In the progressive corner is the democratic socialist, the young democratic socialist whose rapid ascent and grassroots campaign has brought international attention. On the establishment side is Andrew Cuomo, the ex- Democratic New York governor now running as an independent – and benefiting from the support of ultra-rich donors and corporations.

With days to go, it is the progressive, the former longshot who beat his opponent in the party primary who is firmly installed as the frontrunner. Mamdani, who has campaigned on a platform of economic justice and pledged to freeze rent for about two million city residents, has led his rival by double-digits across all surveys taken in October, and it is very much the progressive's race to lose.

A Bitter Contest

However, the former governor, who resigned as governor in 2021 amid allegations of misconduct, has made it clear he will fight to the finish, and not necessarily in an above-the-belt manner. He has criticized Mamdani's objectives as unrealistic, and in the final stretch chuckled along as a radio host made anti-Muslim comments about Mamdani, who is a Muslim. Two weeks ago, the independent was strongly criticized as bigoted after sharing an artificial intelligence video that featured a series of racial caricatures and showed his opponent releasing a convicts.

This represents a rather grubby end to an election that could be critical to the path that the party, struggling in its response to the former president's authoritarian grabs, takes in the coming years.

Broader Consequences

Should the progressive wins convincingly, the party establishment who have refused to endorse his bid will be compelled to address a platform that has resonated with Americans' anger at economic disparity, soaring price rises and the establishment. It would be difficult for the Senate leader and the House leader not to embrace at least some of the candidate's ambitious ideas about affordability, given the fresh face has generated an enthusiasm within the Democratic ranks perhaps not seen since the Vermont senator ran for president in 2016.

However, if the former governor, who had been predicted to sail to victory in the Democratic primary, complete a remarkable comeback win, it could cement national Democrats' existing approach of cautious, uninspiring resistance – a strategy that has infuriated grassroots members. 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 polls show the present version of the party is widely disliked nationwide.

Campaign Energy

Voters in New York seem to prefer the Mamdani vision. Surveys show that Mamdani supporters are far more enthusiastic about their candidate than his opponent's supporters, something that has been evident throughout the campaign. 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 metropolis has attracted an army of more than 50,000 supporters, many of them youth or first-time voters.

Personal Attacks

Yet, the former governor, 67, isn't giving up. And with the risks against him, the former governor has resorted to negative campaigning in recent weeks.

Following extensive launching various attacks at Mamdani to see what might resonate, Cuomo has concentrated on targeting Mamdani directly. He has labelled Mamdani, who was of Ugandan origin to Indian parents, an "radical", and appeared on Fox Business for an interview with Maria Bartiromo, where Cuomo claimed New York “will not survive” Mamdani as city leader. It hit bottom recently, when the former governor laughed along and said “that’s another problem” after a broadcaster said the candidate 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 the capital and threatened to take similar action to New York, has said about the progressive, and perhaps that shouldn’t come as a surprise. A set of billionaire New Yorkers, including some who contributed to Trump in the 2024 election, have pumped millions into trying to get Cuomo into office, as other influential figures have urged the Republican candidate to drop out from the contest.

Candidate Backgrounds

For the Cuomo camp, and his billionaire supporters, are worried, it should not have reached to this point. When the assemblyman, one of 150 New York state assembly members, launched his mayoral bid in October 2024, few had heard of him, and in reality, few 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 became New York governor in 2011, 17 years after his father, Mario Cuomo, left office from the identical role.

The progressive, who was elected to the New York state assembly in 2020, does not have the same political heritage. But his commitment to providing no-cost transit and affordable child services – along with the freeze-the-rent pledge – present a brighter outlook of the city's direction than Cuomo’s dire warnings about “mayhem” and unfettered crime, and his vow to increase police presence.

Recent Challenges

Nevertheless, Mamdani has faced difficulties in recent days, after footage surfaced suggesting him suggesting the New York police department and the IDF were intertwined.

“We have to make clear that when the pressure of the NYPD is on your throat, it’s been influenced by the IDF,” Mamdani said in the recording, recorded at a Democratic Socialists of America gathering in 2023. Mamdani, a longtime critic of Israel who has said the country is committing genocide in the Palestinian territory, suggested he was criticizing cooperative programs between the NYPD and IDF.

Emotional Response

With the election nearing, Mamdani appears to have won 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, the candidate recalled how, when he first ran for the legislature, a Muslim uncle advised to him that he did not have to disclose about his religion. It was a lesson, Mamdani 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 embrace 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.”
