Residents of the Big Apple will learn who will be their new city leader this election day, in a race that will determine who runs and defends the country's largest city at a moment when Donald Trump has threatened to send military troops to the city.

Against that backdrop, New York has experienced a race for mayor that has matched two distinctly opposing Democrats against each other. The election has turned into an increasingly bitter face-off, marked by alleged racism 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 Rising Progressive

In the progressive corner is Zohran Mamdani, the young democratic socialist whose rapid ascent and grassroots campaign has attracted international attention. Representing the old guard is the former governor, the ex- New York governor now running as an independent – and enjoying the backing of ultra-rich donors and big business.

As the election approaches, it is Mamdani, the former longshot who defeated his opponent in the party primary who is firmly installed as the leading candidate. The candidate, who has run on a agenda of economic justice and pledged to halt rent increases for about 2 million city residents, has outpaced his rival by double-digits in every poll taken in the fall, and it is very much the progressive's race to throw away.

A Bitter Contest

However, Cuomo, who stepped down as governor in recent years amid accusations of sexual harassment, has made it clear he will fight to the end, and not necessarily in an fair fashion. He has criticized Mamdani's objectives as unrealistic, and in recent days chuckled along as a broadcaster made anti-Muslim comments about Mamdani, who is Muslim. Recently, Cuomo was strongly criticized as racist after sharing an artificial intelligence video that included a slew of racial caricatures and showed Mamdani releasing a group of criminals.

This represents a particularly ugly end to an race that could be critical to the direction that the Democratic party, struggling in its response to the former president's power moves, adopts in the coming years.

Broader Consequences

If Mamdani secures a clear victory, the establishment party leaders who have refused to endorse his campaign will be compelled to address a message that has appealed to Americans' anger at economic disparity, soaring price rises and the establishment. It would be difficult for the Senate leader and Hakeem Jeffries not to adopt at least some 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 in 2016.

Conversely, if the former governor, who had been predicted to win easily in the Democratic primary, complete a surprising riches-to-rags-to-riches victory, it could reinforce the party's existing approach of considered, uninspiring opposition – a tactic that has infuriated grassroots members. A NYC rejection of the progressive's progressive, positive message could persuade party leaders that the best plan is to remain in the center – even as surveys show the present version of the party is widely disliked nationwide.

Campaign Energy

Residents of New York appear to favor the progressive agenda. Surveys show that his backers are much more excited about their candidate than his opponent's supporters, something that has been evident during the race. The candidate's engaging content on digital platforms, his optimistic vision 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 youth or new participants.

Negative Tactics

Yet, the former governor, 67, continues to fight. And with the stakes against him, the former governor has turned to ugly messaging in recent weeks.

Following extensive throwing basically everything at Mamdani to see what might resonate, the independent has narrowed his focus on targeting Mamdani personally. He has called Mamdani, who was born in Uganda to Indian parents, an “extremist”, and popped up on Fox Business for an discussion with Maria Bartiromo, where Cuomo asserted the city “will not survive” his opponent as city leader. 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 incident.

Political Landscape

This strategy mirrors much of what the former president, who has deployed the military reserves to the capital and warned to do the same to New York, has said about the progressive, and maybe that shouldn’t come as a surprise. A group of billionaire New Yorkers, including some who donated to Trump in the 2024 election, have invested heavily into trying to get the independent into office, as other powerful voices have urged Curtis Sliwa to withdraw from the contest.

Candidate Backgrounds

For the his team, and his billionaire supporters, are concerned, it should never have come to this. When the assemblyman, one of 150 New York state assembly members, launched his mayoral bid in October 2024, few had known him, and in truth, few even paid attention.

Cuomo, by contrast, entered smoothly into the race in March 2025 and became the instant favorite. He was the political heavyweight who seemingly held all the advantages. The classic establishment figure, he had wed a political dynasty member and worked in Bill Clinton’s administration. He became the state's leader in 2011, seventeen years after his father, Mario Cuomo, stepped down from the identical role.

Mamdani, who was voted in 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 rent control promise – present a brighter outlook of the city's direction than Cuomo’s dire warnings about “mayhem” and rising criminal activity, and his vow to increase police presence.

Campaign Controversies

Still, the candidate has faced some challenges in the final phase, after video surfaced suggesting him implying the NYPD and the Israel Defense Forces were intertwined.

“We have to make clear that when the pressure of the police is on your throat, it’s been laced by the Israeli military,” the candidate said in the recording, filmed at a DSA gathering in 2023. Mamdani, a vocal opponent of the Israeli government who has said the country is committing genocide in the Palestinian territory, suggested he was criticizing joint training exercises between the NYPD and IDF.

Emotional Response

With the election nearing, the candidate appears to have won sympathy and support, however, for his reaction to his opponent's escalating attacks.

Mamdani responded to Cuomo’s terrorism comments in an emotional video. In it, Mamdani recalled how, when he first campaigned for state assembly, a family member suggested to him that he did not have to tell people about his Muslim faith. It was a realization, he said, that many Muslim New Yorkers had been taught “again and again”: “That security could only be found in the margins of our city. That it is in those hidden spaces alone where followers of Islam could embrace their true selves, and that if we were to emerge from those seclusion, then it is in those shadows that we must set aside our beliefs.”

Speaking to the behavior of Cuomo and Sliwa, who has claimed Mamd
