New Yorkers will find out the identity of their next mayor this Tuesday, in a race that will determine who governs and defends the country's most populous metropolis at a time when Donald Trump has threatened to send armed forces to the city.

In this context, New York has experienced a race for mayor that has pitted two distinctly opposing Democratic figures against each other. The contest has turned into an acrimonious face-off, laced with alleged racial bias and Islamophobia, but it is the ideological divide between the two leading contenders that could have significant consequences for how the Democratic party fares in next year's midterm elections.

The Progressive Challenger

On the left side is the democratic socialist, the young democratic socialist whose rapid ascent and grassroots campaign has attracted international attention. Representing the old guard is Andrew Cuomo, the former New York governor now campaigning independently – and enjoying the backing of wealthy contributors and big business.

As the election approaches, it is the progressive, the one-time underdog who beat his opponent in the Democratic primary who is solidly positioned as the leading candidate. The candidate, who has run on a platform of affordability and promised to freeze rent for about 2 million city residents, has led his rival by double-digits across all surveys taken in October, and it is very much the younger man's election to lose.

A Bitter Contest

However, the former governor, who stepped down as governor in 2021 amid allegations of sexual harassment, has stated clearly he will fight to the end, and not necessarily in an fair manner. He has criticized his opponent's objectives as unrealistic, 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 included a slew of racist stereotypes and showed his opponent releasing a convicts.

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

Broader Consequences

Should Mamdani 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 economic disparity, soaring price rises and the political elite. It would be hard for the Senate leader and Hakeem Jeffries not to embrace at least some of the candidate's ambitious ideas about affordability, given the newcomer has generated an enthusiasm within the Democratic ranks perhaps not witnessed since the Vermont senator ran for president in 2016.

Conversely, should the former governor, who had been predicted to win easily in the Democratic primary, complete a surprising riches-to-rags-to-riches win, it could cement national Democrats' existing approach of considered, uninspiring resistance – a tactic that has angered grassroots members. A NYC rejection 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 nationwide.

Voter Enthusiasm

Residents of the city appear to favor the Mamdani vision. Polls show that his backers are much more excited about their choice than Cuomo backers, something that has been evident throughout the campaign. The candidate's engaging content on digital platforms, his hopeful outlook for the city and his willingness to actually venture 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

Yet, Cuomo, in his late sixties, isn't giving up. And with the stakes stacked against him, the former governor 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 narrowed his focus on attacking Mamdani directly. He has called Mamdani, who was born in Uganda to Indian parents, an “extremist”, and appeared on conservative media for an discussion with a rightwing host, where the candidate claimed New York “will not survive” his opponent as mayor. It reached a nadir recently, when Cuomo chuckled and said “that’s another problem” after a radio host said the candidate would “cheer” another 9/11-style attack.

Campaign Dynamics

The line of attack echoes much of what Trump, who has deployed the national guard to Washington DC and threatened to do the same to NYC, has said about Mamdani, and perhaps that shouldn’t come as a surprise. A group of billionaire New Yorkers, including some who donated to the Republican in the last presidential race, have pumped millions into trying to elect the independent elected, as other powerful voices have pressured Curtis Sliwa to drop out from the race.

Political Histories

For the Cuomo camp, and his billionaire supporters, are concerned, it should never have come to this. When the assemblyman, one of one hundred fifty state legislators, launched his campaign for mayor in last year, few had heard of him, and in reality, few even noticed.

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 apparently held every edge. The classic establishment figure, he had married a political dynasty member and worked in Bill Clinton’s administration. He became New York governor in 2011, 17 years after his father, the former governor, left office from the same position.

Mamdani, who was elected to the New York state assembly 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 brighter outlook of the future than his opponent's dire warnings about “mayhem” and rising criminal activity, and his vow to increase police presence.

Campaign Controversies

Nevertheless, Mamdani has faced some challenges in recent days, after footage emerged suggesting him implying the NYPD and the IDF were intertwined.

“We have to make clear that when the boot of the police is on your neck, it’s been laced by the IDF,” the candidate said in the recording, filmed at a DSA convention in recent years. The progressive, a vocal opponent of Israel who has said the country is engaging in atrocities in Gaza, indicated he was criticizing cooperative programs between the NYPD and IDF.

Powerful Moment

As the race closes, Mamdani appears to have won sympathy and support, however, for his reaction to Cuomo’s increasing rhetoric.

Mamdani responded to Cuomo’s 9/11 remarks in an emotional video. In it, Mamdani remembered how, when he first ran for the legislature, a family member suggested to him that he did not have to tell people about his religion. It was a lesson, he said, that many Muslim New Yorkers had been taught “again and again”: “That security could only be found in the shadows of our city. That it is in those hidden spaces alone where followers of Islam 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 set aside our beliefs.”

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