Residents of the Big Apple will learn who will be their next mayor this election day, in a contest that will determine who governs and defends the nation's most populous metropolis at a time when the former president has threatened to deploy armed forces to the city.

Against that backdrop, New York has witnessed a mayoral election that has pitted two distinctly opposing Democratic figures against one another. The contest has become an increasingly bitter face-off, laced with accusations of racial bias and Islamophobia, but it is the ideological divide between the two leading candidates that could have significant consequences for how the party fares in next year's congressional races.

The Progressive Challenger

In the progressive corner is the democratic socialist, the young democratic socialist whose meteoric rise and grassroots campaign has attracted international attention. On the establishment side is Andrew Cuomo, the former Democratic New York governor now running as an independent – and benefiting from the backing of ultra-rich donors and big business.

With days to go, it is Mamdani, the former longshot who defeated his opponent in the Democratic primary who is firmly installed as the leading candidate. The candidate, who has campaigned on a agenda of affordability and pledged 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 stepped down as the state's leader in 2021 amid allegations of sexual harassment, has made it clear he will battle to the end, and not necessarily in an above-the-belt fashion. He has criticized his opponent's goals as unrealistic, and in the final stretch laughed as a radio host made Islamophobic remarks about Mamdani, who is a Muslim. Recently, the independent was strongly criticized as racist after posting an AI-generated ad that included a series of racial caricatures and showed his opponent freeing a convicts.

It's been a rather grubby conclusion to an race that could be key to the direction that the Democratic party, struggling in its response to Trump's power moves, takes in the coming years.

National Implications

Should the progressive 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 voters' anger at economic disparity, inflation and the establishment. It would be hard for Chuck Schumer and Hakeem Jeffries not to adopt at least a portion of the candidate's ambitious ideas about affordability, given the fresh face has created an enthusiasm within the party perhaps not witnessed since Bernie Sanders campaigned for the White House eight years ago.

Conversely, if Cuomo, who had been expected to sail to victory in the June primary, complete a surprising comeback victory, it could reinforce the party's existing approach of considered, lackluster opposition – a strategy that has angered grassroots members. A New York rejection of the progressive's optimistic platform could convince Schumer and Jeffries that the best plan is to stick to the political center – even as surveys show the current iteration of the Democratic party is widely disliked across the country.

Voter Enthusiasm

Residents of the city seem to prefer the progressive agenda. Polls show that his backers are far more enthusiastic about their candidate than Cuomo backers, something that has been evident throughout the campaign. Mamdani's engaging content on digital platforms, his optimistic vision for the city and his willingness to actually get out and connect with voters in the metropolis has drawn an army of more than 50,000 supporters, many of them youth or new participants.

Negative Tactics

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

Following extensive throwing basically everything at his opponent to see what might stick, Cuomo has narrowed his focus on attacking the candidate personally. He has labelled Mamdani, who was born in Uganda to Indian parents, an "radical", and popped up on conservative media for an discussion with a rightwing host, where the candidate claimed the city “will not survive” Mamdani as mayor. 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 9/11-style attack.

Political Landscape

This strategy echoes much of what the former president, 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 wealthy residents, including some who contributed to Trump in the last presidential race, have invested heavily into trying to elect the independent elected, as other powerful voices have urged Curtis Sliwa to withdraw from the race.

Political Histories

For the Cuomo camp, and his wealthy backers, are concerned, it should never have come to this point. When Mamdani, one of one hundred fifty New York state assembly members, launched his campaign for mayor in last year, few had heard of him, and in truth, barely anyone even paid attention.

Cuomo, by comparison, entered smoothly into the contest in March 2025 and became the immediate frontrunner. He was the political heavyweight who apparently held every edge. The quintessential political insider, he had married a political dynasty member and served in Bill Clinton’s administration. He became New York governor in 2011, seventeen years after his father, 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 no-cost transit and affordable child services – along with the rent control promise – offer a brighter outlook of the future than Cuomo’s pessimistic predictions about “mayhem” and unfettered crime, and his promise to hire more police officers.

Recent Challenges

Nevertheless, the candidate has encountered some challenges in recent days, after footage emerged appearing to show him implying the New York police department and the IDF were intertwined.

“We have to make clear that when the boot of the NYPD is on your neck, it’s been influenced by the Israeli military,” the candidate said in the clip, recorded at a DSA gathering in 2023. The progressive, a longtime critic of Israel who has said the nation 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.

Mamdani responded to the independent's 9/11 remarks in an emotional video. In it, the candidate recalled how, when he first ran 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 Muslim New Yorkers had been taught “again and again”: “That safety could only be found in the margins of our city. That it is in those shadows alone where followers of Islam could embrace their true selves, and that if we were to step out from those shadows, then it is in those silence that we must leave our faith.”

Addressing the actions of Cuomo and Sliwa, who has alleged Mamd
