New Yorkers will find out the identity of their new city leader this election day, in a race that will decide who runs and protects the nation's largest city at a time when the former president has threatened to deploy armed forces to the city.

Against that backdrop, New York has witnessed a race for mayor that has matched two very different Democrats against one another. The election has turned into an acrimonious showdown, marked by alleged racism and Islamophobia, but it is the ideological divide between the two main contenders that could have significant consequences for how the Democratic party performs in next year's congressional races.

The Rising Progressive

In the progressive corner is Zohran Mamdani, the 34-year-old progressive candidate whose rapid ascent and grassroots campaign has attracted international attention. Representing the old guard is Andrew Cuomo, the ex- Democratic New York governor now campaigning independently – and benefiting from the support of wealthy contributors and big business.

As the election approaches, it is Mamdani, the one-time underdog who beat Cuomo in the party primary who is solidly positioned as the frontrunner. Mamdani, who has campaigned on a agenda of affordability and promised to halt rent increases for about 2 million New Yorkers, has outpaced his rival by double-digits in every poll conducted in the fall, and it is very much the younger man's race to lose.

The Controversial Campaign

However, Cuomo, who resigned as governor in 2021 amid allegations of misconduct, has made it clear he will battle to the finish, and not necessarily in an above-the-belt fashion. He has trashed Mamdani's goals as unachievable, and in the final stretch laughed as a broadcaster made anti-Muslim comments about the candidate, who is a Muslim. Recently, the independent was strongly criticized as bigoted after posting an AI-generated ad that included a slew of racial caricatures and showed Mamdani freeing a convicts.

It's been a rather grubby conclusion to an election that could be key to the path that the party, struggling in its response to Trump's power moves, adopts in the coming years.

National Implications

Should Mamdani secures a clear victory, the party establishment who have declined to support his bid will be compelled to address a platform that has resonated with Americans' frustration at inequality, inflation and the establishment. It would be difficult for the Senate leader and the House leader not to embrace at least some of the candidate's ambitious ideas about economic justice, given the fresh face has created an enthusiasm within the Democratic ranks perhaps not witnessed since the Vermont senator campaigned for the White House eight years ago.

Conversely, if Cuomo, who had been predicted to win easily in the Democratic primary, complete a remarkable comeback win, it could cement the party's existing approach of cautious, uninspiring resistance – a strategy that has angered the party base. A NYC rejection of the progressive's progressive, positive message could persuade party leaders that the wisest course is to stick to the political center – even as surveys show the current iteration of the Democratic party is deeply unpopular across the country.

Voter Enthusiasm

Residents of New York appear to favor the Mamdani vision. Surveys show that his backers are much more excited about their choice than his opponent's supporters, something that has been apparent throughout the campaign. The candidate's engaging content on social media, his hopeful outlook for New York and his willingness to actually venture out and connect with voters in the city has attracted an army of more than 50,000 volunteers, many of them youth or new participants.

Negative Tactics

However, Cuomo, 67, isn't giving up. And with the risks stacked against him, the ex-leader has resorted to ugly messaging in recent weeks.

Following extensive throwing basically everything at his opponent to see what might stick, the independent has narrowed his focus on attacking the candidate directly. He has labelled Mamdani, who was of Ugandan origin to Indian parents, an “extremist”, and appeared on conservative media for an interview with a rightwing host, where the candidate asserted the city “will not survive” his opponent as city leader. It reached a nadir recently, when Cuomo laughed along and said “that’s another problem” after a broadcaster said Mamdani would “cheer” another terrorist attack.

Campaign Dynamics

This strategy mirrors much of what the former president, who has deployed the military reserves to Washington DC and threatened to take similar action to New York, has said about the progressive, and maybe that shouldn’t come as a surprise. A set of billionaire New Yorkers, including some who contributed to the Republican in the last presidential race, have pumped millions into trying to elect Cuomo elected, as other powerful voices have urged the Republican candidate to withdraw from the contest.

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, started his campaign for mayor in October 2024, not many had known him, and in reality, barely anyone even paid attention.

Cuomo, by comparison, entered smoothly into the race in March 2025 and became the instant favorite. He was the big beast who apparently held every edge. The quintessential establishment figure, he had married a Kennedy and served in Bill Clinton’s administration. He assumed office as the state's leader in 2011, 17 years after his father, Mario Cuomo, stepped down from the same position.

Mamdani, who was voted in 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 rent control promise – offer a more positive vision of the city's direction than his opponent's pessimistic predictions about “mayhem” and rising criminal activity, and his vow to increase police presence.

Recent Challenges

Still, the candidate has faced some challenges in recent days, after video emerged suggesting him suggesting the New York police department and the Israel Defense Forces were intertwined.

“We have to make clear that when the pressure of the police is on your throat, it’s been influenced by the Israeli military,” the candidate said in the clip, recorded at a DSA convention in recent years. Mamdani, a longtime critic of the Israeli government who has said the country is committing genocide in the Palestinian territory, indicated he was questioning joint training exercises between the city police and Israeli forces.

Emotional Response

With the election nearing, the candidate seems to have gained sympathy and support, however, for his reaction to Cuomo’s escalating attacks.

The progressive responded to the independent's 9/11 remarks in an heartfelt recording. In it, Mamdani remembered how, when he first ran for state assembly, a Muslim uncle suggested to him that he did not have to disclose about his Muslim faith. It was a lesson, he said, that many local Muslims had been told “again and again”: “That safety could only be found in the shadows of our city. That it is in those shadows 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 leave our faith.”
