New Yorkers will discover the identity of their new city leader this election day, in a contest that will decide who runs and defends the nation's most populous metropolis at a time when the former president has vowed to deploy armed forces to the city.

Against that backdrop, New York has experienced a mayoral election that has matched two distinctly opposing Democratic figures against one another. The contest has turned into an acrimonious face-off, marked by alleged racism and anti-Muslim sentiment, but it is the political differences between the two main candidates that could have major implications for how the party performs in next year's midterm elections.

The Progressive Challenger

In the progressive corner is the democratic socialist, the young progressive candidate whose meteoric rise and people-powered movement has brought global notice. On the establishment side is the former governor, the former Democratic New York governor now campaigning independently – and enjoying the backing of wealthy contributors and big business.

With days to go, it is Mamdani, the one-time underdog who defeated Cuomo in the Democratic primary who is solidly positioned as the leading candidate. The candidate, who has run on a platform of affordability and pledged to halt rent increases for about 2 million city residents, has led his rival by significant margins across all surveys conducted in October, and it is very much the younger man's election to lose.

The Controversial Campaign

However, Cuomo, who resigned as the state's leader in recent years amid accusations of sexual harassment, has stated clearly he will battle to the finish, and not necessarily in an fair fashion. He has trashed Mamdani's goals as unrealistic, and in the final stretch chuckled along as a broadcaster made Islamophobic remarks about Mamdani, who is a Muslim. Recently, the independent was widely condemned as racist after sharing an AI-generated ad that featured a slew of racial caricatures and showed Mamdani freeing a group of criminals.

This represents a particularly ugly conclusion to an election that could be key to the path that the Democratic party, floundering in its reaction to the former president's power moves, adopts in the coming years.

Broader Consequences

Should Mamdani wins convincingly, the establishment party leaders who have refused to endorse his bid will be forced to reckon with a message that has appealed to voters' anger at inequality, soaring price rises and the political elite. It would be difficult for Chuck Schumer and the House leader not to embrace at least some of Mamdani's progressive proposals about economic justice, given the fresh face has generated an enthusiasm within the party arguably not seen since the Vermont senator ran for president eight years ago.

Conversely, should the former governor, who had been predicted to sail to victory in the June primary, achieve a remarkable riches-to-rags-to-riches win, it could reinforce national Democrats' existing approach of considered, lackluster resistance – a tactic that has angered the party base. A New York rejection of Mamdani's progressive, positive message could convince party leaders that the wisest course is to remain in the political center – even as surveys show the current iteration of the Democratic party is widely disliked nationwide.

Campaign Energy

Residents of the city seem to prefer the Mamdani vision. Surveys show that Mamdani supporters are far more enthusiastic about their choice than Cuomo backers, something that has been evident during the race. Mamdani's engaging content on digital platforms, his hopeful outlook for New York and his willingness to actually venture out and meet people in the metropolis has drawn an army of more than 50,000 volunteers, many of them youth or new participants.

Personal Attacks

Yet, Cuomo, in his late sixties, isn't giving up. And with the risks against him, the ex-leader has turned to negative campaigning in the final days.

Following extensive throwing basically everything at Mamdani to see what might resonate, the independent has narrowed his focus on attacking Mamdani personally. He has called Mamdani, who was of Ugandan origin to Indian parents, an “extremist”, and appeared on conservative media for an interview with Maria Bartiromo, where the candidate claimed the city “will not survive” his opponent as mayor. It hit bottom recently, when the former governor chuckled and said “that’s another problem” after a broadcaster said the candidate would “cheer” another 9/11-style incident.

Campaign Dynamics

The line of attack echoes much of what Trump, who has deployed the military reserves to Washington DC and threatened to do the same to New York, has said about the progressive, and perhaps that shouldn’t come as a surprise. A group of wealthy residents, including some who donated to the Republican in the last presidential race, have pumped millions into trying to elect Cuomo into office, as other powerful voices have pressured Curtis Sliwa to withdraw from the contest.

Candidate Backgrounds

For the Cuomo camp, and his wealthy backers, are worried, it should not have reached to this point. When Mamdani, one of one hundred fifty state legislators, started his campaign for mayor in October 2024, not many had known him, and in truth, few even noticed.

Cuomo, by contrast, eased his way into the race in March 2025 and became the instant favorite. He was the political heavyweight who apparently held all the advantages. The quintessential political insider, he had married a political dynasty member and worked in Bill Clinton’s administration. He assumed office as New York governor in 2011, seventeen years after his parent, Mario Cuomo, stepped down from the identical role.

Mamdani, who was elected to the state legislature in 2020, does not have the same political heritage. But his commitment to providing free buses and affordable child services – along with the freeze-the-rent pledge – offer a more positive vision of the future than Cuomo’s dire warnings 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 video 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 police is on your neck, it’s been laced by the Israeli military,” Mamdani said in the recording, filmed at a DSA convention in 2023. The progressive, a longtime critic of Israel who has said the country is engaging in atrocities in the Palestinian territory, suggested he was criticizing joint training exercises between the city police and IDF.

Powerful Moment

With the election nearing, the candidate seems to have gained sympathy and support, however, for his reaction to Cuomo’s escalating attacks.

Mamdani responded to Cuomo’s terrorism comments in an emotional video. In it, the candidate remembered how, when he first ran for the legislature, a family member suggested 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 told “again and again”: “That security could only be found in the shadows of our city. That it is in those shadows alone where Muslims could express their full identities, and that if we were to step out from those shadows, then it is in those shadows that we must leave our faith.”
