New Yorkers will discover who will be their next mayor this Tuesday, in a race that will decide who governs and defends the nation's largest city at a time when Donald Trump has threatened to deploy military troops to the city.

Against that backdrop, New York has witnessed a mayoral election that has pitted two distinctly opposing Democrats against each other. The election has turned into an acrimonious face-off, laced with alleged racial bias and anti-Muslim sentiment, but it is the ideological divide between the two leading candidates that could have major implications for how the party fares in next year's congressional races.

The Progressive Challenger

On the left side is the democratic socialist, the young progressive candidate whose meteoric rise and grassroots campaign has attracted international attention. On the establishment side is the former governor, the ex- Democratic New York governor now running as an independent – and enjoying the support of wealthy contributors and corporations.

As the election approaches, it is the progressive, the former longshot who defeated Cuomo in the Democratic primary who is solidly positioned as the frontrunner. Mamdani, who has campaigned on a platform of affordability and pledged to freeze rent for about two million New Yorkers, has outpaced Cuomo by significant margins across all surveys taken in the fall, and it is very much the younger man's election to lose.

A Bitter Contest

Yet, Cuomo, who stepped down as governor in recent years amid accusations of misconduct, has made it clear he will fight to the end, and not necessarily in an above-the-belt fashion. He has criticized his opponent's goals as unachievable, and in the final stretch laughed as a broadcaster made anti-Muslim comments about Mamdani, who is Muslim. Two weeks ago, the independent was strongly criticized as racist after sharing an artificial intelligence video that featured a slew of racial caricatures and showed Mamdani releasing a group of criminals.

It's been a rather grubby conclusion to an race that could be key to the path that the party, floundering in its reaction to the former president's power moves, takes in the coming years.

Broader Consequences

If the progressive wins convincingly, the party establishment who have declined to support his bid will be forced to reckon with a message that has appealed to voters' frustration at economic disparity, soaring price rises and the establishment. It would be hard for the Senate leader and Hakeem Jeffries not to adopt at least some of Mamdani's ambitious ideas about affordability, given the newcomer has generated an enthusiasm within the party perhaps not seen since Bernie Sanders ran for president in 2016.

Conversely, if Cuomo, who had been expected to sail to victory in the June primary, achieve a surprising comeback victory, it could reinforce the party's current model of cautious, uninspiring resistance – a tactic that has infuriated grassroots members. A New York defeat of the progressive's progressive, positive message could persuade Schumer and Jeffries that the wisest course is to remain in the political center – even as surveys show the current iteration of the Democratic party is deeply unpopular across the country.

Voter Enthusiasm

Voters in the city appear to favor the progressive agenda. Surveys show that Mamdani supporters are much more excited about their choice than his opponent's supporters, something that has been evident during the race. Mamdani's snappy videos on digital platforms, his optimistic vision for New York and his readiness to actually get out and connect with voters in the metropolis has drawn an force of over fifty thousand supporters, many of them young or new participants.

Negative Tactics

Yet, the former governor, in his late sixties, isn't giving up. And with the risks stacked against him, the ex-leader has turned to ugly messaging in recent weeks.

After spending months launching various attacks at his opponent to see what might stick, the independent has concentrated on attacking the candidate personally. He has called Mamdani, who was of Ugandan origin to Indian parents, an "radical", and appeared on Fox Business for an discussion with a rightwing host, where Cuomo claimed the city “will not survive” his opponent as mayor. It reached a nadir recently, when Cuomo laughed along and said “that’s another problem” after a broadcaster said Mamdani would “cheer” another terrorist incident.

Campaign Dynamics

This strategy echoes much of what the former president, who has sent the military reserves to the capital and threatened to do the same to New York, has said about Mamdani, and perhaps that is expected. A set of wealthy residents, including some who donated to the Republican in the 2024 election, have invested heavily into trying to get Cuomo into office, as other powerful voices have pressured Curtis Sliwa to drop out from the contest.

Political Histories

For the his team, and his wealthy backers, are worried, it should never have come to this point. When the assemblyman, one of 150 state legislators, started his campaign for mayor in last year, not many had known him, and in reality, barely anyone even noticed.

The former governor, by contrast, eased his way into the contest in March 2025 and became the immediate frontrunner. He was the political heavyweight who seemingly held every edge. The classic establishment figure, he had wed a political dynasty member and served in a Democratic presidency. He became the state's leader in over a decade ago, seventeen years after his parent, the former governor, stepped down from the same position.

Mamdani, who was voted in to the state legislature in recently, does not have the same political heritage. But his commitment to providing free buses and free childcare – along with the rent control promise – offer a brighter outlook of the future than his opponent's dire warnings about “mayhem” and rising criminal activity, and his promise to increase police presence.

Campaign Controversies

Still, Mamdani has faced some challenges in the final phase, after video surfaced suggesting him implying 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 influenced by the Israeli military,” Mamdani said in the recording, recorded at a Democratic Socialists of America convention in 2023. Mamdani, a vocal opponent of Israel who has said the country is committing genocide in Gaza, suggested he was questioning cooperative programs between the city police and Israeli forces.

Emotional Response

As the race closes, Mamdani seems to have gained sympathy and support, however, for his response to his opponent's increasing rhetoric.

Mamdani responded to Cuomo’s 9/11 remarks in an emotional video. In it, Mamdani recalled how, when he first campaigned for the legislature, a family member suggested to him that he did not have to disclose about his Muslim faith. It was a realization, 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 followers of Islam could embrace their full identities, and that if we were to emerge from those seclusion, then it is in those silence that we must leave our beliefs.”

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