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

In this context, New York has witnessed a mayoral election that has pitted two very different Democrats against each other. The contest has turned into an acrimonious face-off, laced with alleged racial bias and Islamophobia, but it is the political differences between the two main candidates that could have major implications for how the Democratic party fares in next year's midterm elections.

The Rising Progressive

In the progressive corner is the democratic socialist, the young progressive candidate whose rapid ascent and grassroots campaign has attracted global notice. Representing the old guard is Andrew Cuomo, the former New York governor now running as an independent – and benefiting from the backing of ultra-rich donors and corporations.

As the election approaches, it is Mamdani, the one-time underdog who defeated his opponent in the Democratic primary who is firmly installed as the frontrunner. The candidate, who has run on a agenda of affordability and pledged to halt rent increases for about 2 million New Yorkers, has led Cuomo by significant margins in every poll conducted in the fall, and it is very much the younger man's election to lose.

The Controversial Campaign

Yet, Cuomo, who resigned as the state's leader in recent years amid accusations of sexual harassment, has made it clear he will fight to the end, and not necessarily in an fair manner. He has criticized Mamdani's goals as unachievable, and in recent days laughed as a broadcaster made Islamophobic remarks about the candidate, who is a Muslim. Recently, the independent was widely condemned as bigoted after sharing an AI-generated ad that included a series of racist stereotypes and showed Mamdani releasing a convicts.

It's been a particularly ugly conclusion to an race that could be key to the path that the Democratic party, floundering in its response to Trump's power moves, adopts in the near future.

Broader Consequences

Should the progressive wins convincingly, the establishment party leaders who have declined to support his campaign will be forced to reckon with a message that has appealed to voters' frustration at inequality, inflation and the establishment. It would be difficult for the Senate leader and the House leader not to adopt at least a portion of the candidate's progressive proposals about economic justice, given the fresh face has created an enthusiasm within the Democratic ranks arguably not seen since Bernie Sanders ran for president in 2016.

However, should Cuomo, who had been predicted to sail to victory in the June primary, achieve a remarkable comeback victory, it could cement national Democrats' existing approach of cautious, lackluster resistance – a tactic that has angered the party base. A New York defeat of Mamdani's optimistic platform could persuade party leaders that the best plan is to stick to the political center – even as surveys show the present version of the party is widely disliked across the country.

Campaign Energy

Residents of the city seem to prefer the Mamdani vision. Surveys show that his backers are much more excited about their choice than Cuomo backers, something that has been apparent during the race. The candidate's snappy videos on digital platforms, his hopeful outlook for the city and his readiness to actually venture out and meet people in the metropolis has attracted an army of more than 50,000 supporters, many of them young or new participants.

Personal Attacks

However, the former governor, in his late sixties, isn't giving up. And with the stakes stacked against him, the former governor has resorted to negative campaigning in the final days.

Following extensive throwing basically everything at his opponent to see what might stick, Cuomo has concentrated on attacking Mamdani directly. He has labelled Mamdani, who was of Ugandan origin to Indian parents, an "radical", and appeared on Fox Business for an interview with Maria Bartiromo, where the candidate claimed the city “will not survive” his opponent as city leader. It reached a nadir recently, when Cuomo chuckled and said “that’s another problem” after a broadcaster said Mamdani would “cheer” another 9/11-style incident.

Political Landscape

The line of attack echoes much of what Trump, who has sent the national guard to Washington DC and threatened to take similar action to NYC, has said about the progressive, and perhaps that is expected. A group of billionaire New Yorkers, including some who donated to Trump in the last presidential race, have invested heavily into trying to elect Cuomo into office, as other influential figures have urged the Republican candidate to withdraw from the race.

Political Histories

For the his team, and his billionaire supporters, are concerned, it should never have come to this. When the assemblyman, one of one hundred fifty New York state assembly members, launched his mayoral bid in October 2024, few had heard of him, and in reality, few even noticed.

The former governor, by comparison, entered smoothly into the race in March 2025 and became the immediate frontrunner. He was the big beast who seemingly held every edge. The classic establishment figure, he had married a political dynasty member and worked in a Democratic presidency. He became New York governor in 2011, 17 years after his father, the former governor, 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 brighter outlook of the future than his opponent's dire warnings about “mayhem” and unfettered crime, and his vow to increase police presence.

Campaign Controversies

Still, Mamdani has faced some challenges in the final phase, after video surfaced appearing to show him implying the NYPD and the Israel Defense Forces were intertwined.

“We have to make clear that when the boot of the NYPD is on your throat, it’s been laced by the Israeli military,” the candidate said in the recording, recorded at a DSA convention in recent years. The progressive, a longtime critic of the Israeli government who has said the country is committing genocide in Gaza, indicated he was criticizing joint training exercises between the NYPD and IDF.

Emotional Response

With the election nearing, the candidate appears to have won empathy and backing, however, for his reaction to Cuomo’s increasing rhetoric.

Mamdani addressed the independent's 9/11 remarks in an heartfelt recording. In it, Mamdani recalled how, when he first ran for the legislature, a Muslim uncle suggested to him that he did not have to disclose about his Muslim faith. It was a lesson, Mamdani said, that many local Muslims had been taught “again and again”: “That safety could only be found in the shadows of our community. That it is in those hidden spaces alone where followers of Islam could express their true selves, and that if we were to step out from those seclusion, then it is in those silence that we must leave our beliefs.”
