New Yorkers 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 largest city at a moment when the former president has threatened to send armed forces to the urban center.

Against that backdrop, New York has witnessed a mayoral election that has matched two very different Democrats against one another. The election has become an acrimonious face-off, marked by alleged racial bias and Islamophobia, but it is the political differences between the two leading candidates that could have significant consequences for how the party fares in next year's congressional races.

The Rising Progressive

On the left side is the democratic socialist, the young democratic socialist whose meteoric rise and people-powered movement 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 big business.

With days to go, it is Mamdani, the one-time underdog who beat his opponent in the party primary who is firmly installed as the frontrunner. Mamdani, who has run on a platform of affordability and promised to halt rent increases for about 2 million New Yorkers, has outpaced Cuomo by significant margins across all surveys conducted in October, and it is very much the younger man's election to lose.

A Bitter Contest

However, Cuomo, who resigned as governor in 2021 amid allegations of sexual harassment, has stated clearly he will battle to the end, and not necessarily in an fair manner. He has criticized his opponent's goals as unachievable, and in recent days laughed 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 featured a slew of racial caricatures and showed Mamdani freeing a group of criminals.

It's been a particularly ugly conclusion to an election that could be key to the path that the Democratic party, floundering in its response to the former president's power moves, takes in the coming years.

Broader Consequences

If the progressive wins convincingly, the party establishment who have refused to endorse his bid will be forced to reckon with a message that has appealed to voters' anger at economic disparity, inflation and the establishment. It would be hard for Chuck Schumer and Hakeem Jeffries not to adopt at least some of Mamdani's progressive proposals about affordability, given the newcomer has generated an enthusiasm within the Democratic ranks arguably not witnessed since Bernie Sanders ran for president eight years ago.

However, should Cuomo, who had been predicted to sail to victory in the June primary, achieve a remarkable comeback victory, it could cement the party's current model of considered, uninspiring resistance – a tactic that has infuriated grassroots members. A New York rejection of the progressive's optimistic platform could persuade Schumer and Jeffries that the wisest course is to remain in the center – even as polls show the current iteration of the Democratic party is deeply unpopular across the country.

Campaign Energy

Voters in New York appear to favor the Mamdani vision. Surveys show that Mamdani supporters are far more enthusiastic about their candidate than Cuomo backers, something that has been evident throughout the campaign. The candidate's snappy videos on social media, his optimistic vision for New York and his readiness to actually get out and meet people in the metropolis has drawn an army of more than 50,000 volunteers, many of them youth or new participants.

Negative Tactics

However, the former governor, in his late sixties, continues to fight. And with the stakes stacked against him, the former governor has turned to negative campaigning in the final days.

After spending months throwing basically everything at Mamdani to see what might stick, Cuomo has narrowed his focus on targeting Mamdani personally. He has labelled Mamdani, who was of Ugandan origin to South Asian heritage, an “extremist”, and popped up on Fox Business for an interview with Maria Bartiromo, where the candidate claimed the city “will not survive” Mamdani as city leader. It hit bottom last week, when the former governor laughed along and said “that’s another problem” after a radio host said Mamdani would “cheer” another 9/11-style incident.

Campaign Dynamics

The line of attack mirrors much of what Trump, who has deployed the national guard to the capital and threatened to do the same to NYC, has said about Mamdani, and maybe that is expected. A set of billionaire New Yorkers, including some who contributed to Trump in the last presidential race, have pumped millions into trying to get the independent into office, as other influential figures have pressured the Republican candidate to drop out from the contest.

Candidate Backgrounds

As far as the Cuomo camp, and his wealthy backers, are worried, it should not have reached to this. When the assemblyman, one of one hundred fifty state legislators, launched his mayoral bid in last year, not many had known him, and in reality, few even paid attention.

Cuomo, by comparison, entered smoothly into the race in March 2025 and became the instant favorite. He was the big beast who apparently held every edge. The quintessential 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, left office from the identical role.

The progressive, 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 affordable child services – along with the freeze-the-rent pledge – offer a brighter outlook of the future than his opponent's pessimistic predictions about “mayhem” and rising criminal activity, and his promise to hire more police officers.

Campaign Controversies

Nevertheless, Mamdani has faced some challenges in the final phase, after footage emerged suggesting him suggesting the NYPD and the IDF were intertwined.

“We have to make clear that when the pressure of the NYPD is on your neck, it’s been influenced by the IDF,” the candidate said in the recording, recorded at a Democratic Socialists of America convention in recent years. Mamdani, a vocal opponent of Israel who has said the country is committing genocide in the Palestinian territory, indicated he was questioning cooperative programs between the city police and Israeli forces.

Powerful Moment

As the race closes, Mamdani appears to have won sympathy and support, however, for his response to Cuomo’s increasing rhetoric.

The progressive addressed the independent's 9/11 remarks in an heartfelt recording. In it, the candidate recalled how, when he first campaigned for the legislature, a Muslim uncle advised 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 safety could only be found in the margins of our community. That it is in those shadows 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.”

Addressing the behavior of his opponents, who has alleged Mamd
