Residents of the Big Apple will find out the identity of their new city leader this Tuesday, in a race that will determine who governs and defends the country's most populous metropolis at a time when the former president has threatened to send military troops to the urban center.

Against that backdrop, New York has witnessed a mayoral election that has matched two very different Democrats against one another. The election has turned into an acrimonious face-off, marked by alleged racial bias and anti-Muslim sentiment, but it is the ideological divide between the two main candidates that could have significant consequences for how the Democratic party performs in next year's midterm elections.

The Progressive Challenger

On the left side is the democratic socialist, the 34-year-old progressive candidate whose meteoric rise and grassroots campaign has attracted international attention. On the establishment side is Andrew Cuomo, the former Democratic New York governor now campaigning independently – and enjoying the backing of ultra-rich donors and big business.

As the election approaches, it is the progressive, the one-time underdog who defeated Cuomo in the Democratic primary who is firmly installed as the leading candidate. Mamdani, who has campaigned on a platform of economic justice and pledged to freeze rent for about 2 million city residents, has led Cuomo by double-digits across all surveys taken in the fall, and it is very much the younger man's race to throw away.

The Controversial Campaign

Yet, Cuomo, who resigned as governor in recent years amid accusations of sexual harassment, has made it clear he will battle to the end, and not necessarily in an above-the-belt manner. He has trashed his opponent's goals as unachievable, and in the final stretch laughed as a radio host made anti-Muslim comments about Mamdani, who is Muslim. Two weeks ago, Cuomo was widely condemned as bigoted after posting an artificial intelligence video that featured a slew of racial caricatures and showed Mamdani releasing a group of criminals.

It's been a particularly ugly conclusion to an election that could be key to the path that the party, floundering in its reaction to Trump's power moves, takes in the coming years.

Broader Consequences

If Mamdani wins convincingly, the establishment party leaders who have declined to support his bid will be forced to reckon with a platform that has appealed to voters' anger at economic disparity, inflation and the political elite. It would be difficult for Chuck Schumer and the House leader not to adopt at least some of the candidate's progressive proposals about affordability, given the newcomer has created an enthusiasm within the party perhaps not seen since Bernie Sanders campaigned for the White House in 2016.

However, if the former governor, who had been expected to win easily in the Democratic primary, complete a surprising comeback victory, it could cement national Democrats' current model of considered, lackluster opposition – a strategy that has angered grassroots members. A NYC defeat of Mamdani's progressive, positive message could convince Schumer and Jeffries that the best plan is to stick to the center – even as surveys show the current iteration of the Democratic party is widely disliked nationwide.

Campaign Energy

Voters in New York seem to prefer the progressive agenda. Surveys show that his backers are far more enthusiastic about their candidate than Cuomo backers, something that has been evident throughout the campaign. 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 metropolis has attracted an army of more than 50,000 volunteers, many of them young or first-time voters.

Personal Attacks

However, Cuomo, 67, continues to fight. And with the risks against him, the former governor has resorted to negative campaigning in the final days.

After spending months launching various attacks at Mamdani to see what might resonate, the independent has narrowed his focus on attacking the candidate directly. He has labelled his rival, who was born in Uganda to Indian parents, an “extremist”, and popped up on conservative media for an interview with a rightwing host, where Cuomo claimed the city “will not survive” his opponent 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 mirrors much of what Trump, who has deployed the military reserves to the capital and warned to take similar action to New York, has said about the progressive, and maybe that shouldn’t come as a surprise. A set of wealthy residents, including some who donated to the Republican in the 2024 election, have invested heavily into trying to elect the independent elected, as other powerful voices have pressured Curtis Sliwa to drop out from the race.

Political Histories

As far as the Cuomo camp, and his wealthy backers, are concerned, it should never have come to this. When the assemblyman, one of one hundred fifty state legislators, started his mayoral bid in last year, not many had heard of him, and in reality, barely anyone even paid attention.

The former governor, by contrast, eased his way into the race in March 2025 and became the instant favorite. He was the big beast who seemingly held every edge. The classic political insider, he had married a political dynasty member and worked in a Democratic presidency. He assumed office as the state's leader in over a decade ago, seventeen years after his father, the former governor, left office from the same position.

Mamdani, who was voted in to the state legislature in 2020, does not have the comparable background. But his commitment to providing no-cost transit and affordable child services – along with the freeze-the-rent pledge – offer a more positive vision of the future than his opponent's dire warnings about “mayhem” and unfettered crime, and his vow to hire more police officers.

Campaign Controversies

Still, the candidate has encountered some challenges in the final phase, after footage emerged appearing to show him suggesting the NYPD and the Israel Defense Forces were connected.

“We have to make clear that when the pressure of the police is on your neck, it’s been laced by the Israeli military,” the candidate said in the recording, filmed at a Democratic Socialists of America convention in 2023. The progressive, a longtime critic 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 Israeli forces.

Emotional Response

As the race closes, the candidate appears to have won empathy and backing, however, for his response to his opponent's increasing rhetoric.

The progressive responded to the independent's 9/11 remarks in an heartfelt recording. In it, Mamdani recalled how, when he first campaigned for state assembly, a Muslim uncle suggested to him that he did not have to tell people about his Muslim faith. It was a realization, Mamdani said, that many local Muslims had been told “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 full identities, and that if we were to emerge from those shadows, then it is in those silence that we must leave our faith.”

Addressing the behavior of Cuomo and Sliwa, who has claimed Mamd
