New Yorkers will find out the identity of their next mayor this election day, in a race that will determine who governs and defends the nation's largest city at a moment 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 matched two distinctly opposing Democrats against one another. The election has turned into an acrimonious showdown, laced with alleged racism and anti-Muslim sentiment, but it is the ideological divide between the two leading candidates 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 young democratic socialist 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 backing of wealthy contributors and big business.

As the election approaches, it is the progressive, the one-time underdog who defeated his opponent in the party primary who is solidly positioned as the leading candidate. Mamdani, who has run on a platform of economic justice and promised to freeze rent for about two million New Yorkers, has outpaced his rival by double-digits in every poll taken in the fall, and it is very much the progressive's race to lose.

The Controversial Campaign

However, the former governor, who stepped down as governor in 2021 amid accusations of sexual harassment, has stated clearly he will battle to the finish, and not necessarily in an above-the-belt manner. He has criticized his opponent's goals as unachievable, and in recent days laughed as a broadcaster made anti-Muslim comments about the candidate, who is a Muslim. Two weeks ago, the independent was widely condemned as bigoted after posting an AI-generated ad that included a series of racial caricatures and showed his opponent releasing a convicts.

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

National Implications

Should Mamdani secures a clear victory, the establishment party leaders who have refused to endorse his campaign will be forced to reckon with a message that has resonated with Americans' anger at economic disparity, inflation and the establishment. It would be difficult for Chuck Schumer and Hakeem Jeffries not to adopt at least a portion of the candidate's progressive proposals about economic justice, given the newcomer has created an enthusiasm within the party arguably not witnessed since Bernie Sanders ran for president in 2016.

However, if the former governor, who had been expected to win easily in the June primary, complete a remarkable riches-to-rags-to-riches victory, it could cement the party's existing approach of cautious, lackluster opposition – a strategy that has angered the party base. A NYC rejection of Mamdani's optimistic platform could convince party leaders that the wisest course is to remain in the center – even as polls show the current iteration of the party is widely disliked nationwide.

Voter Enthusiasm

Voters in the city seem to prefer the progressive agenda. Polls show that his backers are far more enthusiastic about their candidate than his opponent's supporters, something that has been apparent throughout the campaign. Mamdani's engaging content on social media, his optimistic vision for New York and his willingness to actually get out and meet people in the city has drawn an force of over fifty thousand volunteers, many of them youth or first-time voters.

Personal Attacks

However, the former governor, in his late sixties, isn't giving up. 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 his opponent to see what might resonate, the independent has narrowed his focus on targeting Mamdani directly. He has called Mamdani, who was of Ugandan origin to Indian parents, an “extremist”, and appeared on conservative media for an interview with Maria Bartiromo, where Cuomo claimed New York “will not survive” Mamdani as city leader. It hit bottom recently, when Cuomo laughed along and said “that’s another problem” after a radio host said Mamdani would “cheer” another terrorist incident.

Campaign Dynamics

This strategy mirrors much of what Trump, who has deployed the national guard 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 2024 election, have pumped millions into trying to elect the independent elected, as other influential figures have pressured Curtis Sliwa to withdraw from the race.

Political Histories

For the his team, and his billionaire supporters, are concerned, it should not have reached to this point. When Mamdani, one of 150 New York state assembly members, started his mayoral bid in last year, few had heard of him, and in reality, few even paid attention.

Cuomo, by contrast, entered smoothly into the race in March 2025 and became the immediate frontrunner. He was the political heavyweight who apparently held every edge. The classic political insider, he had wed a Kennedy and served in Bill Clinton’s administration. He assumed office as New York governor in 2011, 17 years after his parent, the former governor, stepped down from the same position.

Mamdani, who was elected to the New York state assembly in recently, does not have the comparable background. But his dedication to providing free buses and free childcare – along with the rent control promise – offer a brighter outlook 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 difficulties in the final phase, after video emerged appearing to show him suggesting the New York police department and the IDF were intertwined.

“We have to make clear that when the pressure of the NYPD is on your throat, it’s been influenced by the IDF,” Mamdani said in the recording, recorded at a DSA convention in 2023. Mamdani, a vocal opponent of the Israeli government who has said the country is committing genocide in Gaza, suggested he was criticizing joint training exercises between the city police and Israeli forces.

Emotional Response

As the race closes, Mamdani appears to have won sympathy and support, however, for his response to his opponent's escalating attacks.

The progressive addressed the independent's terrorism comments in an heartfelt recording. In it, Mamdani remembered how, when he first ran for state assembly, a family member suggested to him that he did not have to tell people about his religion. It was a realization, 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 true selves, and that if we were to step out from those seclusion, then it is in those silence that we must set aside our faith.”

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