New Yorkers will learn who will be their next mayor this election day, in a contest that will decide who governs and defends the nation's most populous metropolis at a time when Donald Trump has threatened to send armed forces to the urban center.

Against that backdrop, New York has witnessed a race for mayor that has pitted two very different Democrats against each other. The contest has become an acrimonious face-off, marked by alleged racism and Islamophobia, but it is the ideological divide between the two main contenders that could have major implications for how the party performs in next year's midterm elections.

The Progressive Challenger

On the left side is Zohran Mamdani, the 34-year-old progressive candidate whose meteoric rise and grassroots campaign has attracted global notice. On the establishment side is the former governor, the former Democratic New York governor now campaigning independently – and benefiting from the backing of ultra-rich donors and big business.

With days to go, it is the progressive, the one-time underdog who defeated his opponent in the party primary who is firmly installed as the leading candidate. Mamdani, who has run on a agenda of affordability and pledged to halt rent increases for about two million city residents, has outpaced Cuomo by double-digits in every poll conducted in October, and it is very much the younger man's race to lose.

The Controversial Campaign

However, the former governor, who resigned as governor in 2021 amid allegations of misconduct, has made it clear he will fight to the finish, and not necessarily in an above-the-belt manner. He has trashed Mamdani's goals as unachievable, and in the final stretch chuckled along as a radio host made Islamophobic remarks about the candidate, who is a Muslim. Two weeks ago, Cuomo was strongly criticized as racist after posting an AI-generated ad that featured a slew of racist stereotypes and showed his opponent freeing a group of criminals.

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

National Implications

Should the progressive wins convincingly, the party establishment who have refused to endorse his bid will be forced to reckon with a platform that has resonated with voters' frustration at economic disparity, inflation and the political elite. It would be hard for the Senate leader and the House leader not to embrace at least some of Mamdani's ambitious ideas about economic justice, given the newcomer has generated an enthusiasm within the party perhaps not witnessed since Bernie Sanders ran for president eight years ago.

Conversely, if the former governor, who had been predicted to win easily in the Democratic primary, complete a surprising comeback win, it could cement the party's current model of cautious, lackluster resistance – a strategy that has infuriated grassroots members. A NYC defeat of the progressive's progressive, positive message could persuade 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 deeply unpopular across the country.

Campaign Energy

Residents of the city seem to prefer the Mamdani vision. Polls show that his backers are much more excited about their candidate than his opponent's supporters, something that has been evident throughout the campaign. The candidate's snappy videos on social media, his hopeful outlook for New York 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.

Negative Tactics

Yet, the former governor, 67, continues to fight. And with the stakes stacked against him, the ex-leader has resorted to negative campaigning in recent weeks.

After spending months launching various attacks at his opponent to see what might resonate, the independent has narrowed his focus on attacking Mamdani directly. He has called Mamdani, who was of Ugandan origin to Indian parents, an “extremist”, and appeared on Fox Business for an interview with Maria Bartiromo, where the candidate claimed New York “will not survive” Mamdani 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 terrorist attack.

Political Landscape

This strategy echoes much of what the former president, who has deployed the military reserves to Washington DC and threatened to take similar action to NYC, has said about the progressive, and perhaps that shouldn’t come as a surprise. A group of wealthy residents, including some who donated to Trump in the last presidential race, have pumped millions into trying to get Cuomo elected, as other powerful voices have pressured the Republican candidate to withdraw from the race.

Political Histories

For the his team, and his billionaire supporters, are worried, it should never have come to this point. When Mamdani, one of 150 state legislators, started his campaign for mayor in last year, few had heard of him, and in truth, barely anyone even noticed.

Cuomo, by contrast, entered smoothly into the contest in March 2025 and became the instant favorite. He was the political heavyweight who seemingly held all the advantages. The classic political insider, he had wed a political dynasty member and served in a Democratic presidency. He became the state's leader in over a decade ago, 17 years after his parent, Mario Cuomo, stepped down from the same position.

Mamdani, who was voted in to the state legislature in 2020, does not have the same political heritage. But his dedication to providing free buses 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 rising criminal activity, and his vow to hire more police officers.

Campaign Controversies

Nevertheless, Mamdani has encountered some challenges in recent days, after footage surfaced suggesting him suggesting the NYPD and the Israel Defense Forces were connected.

“We have to make clear that when the boot 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 recent years. The progressive, a longtime critic of Israel who has said the nation is engaging in atrocities in Gaza, suggested he was questioning cooperative programs between the city police and IDF.

Emotional Response

As the race closes, Mamdani seems to have gained 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 remembered how, when he first ran for the legislature, a Muslim uncle advised to him that he did not have to tell people about his Muslim faith. It was a realization, Mamdani said, that many Muslim New Yorkers had been taught “again and again”: “That security could only be found in the margins of our community. That it is in those shadows alone where followers of Islam could express their full identities, and that if we were to emerge from those seclusion, then it is in those shadows that we must leave our beliefs.”

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