New Yorkers will find out who will be their new city leader this Tuesday, in a race that will determine who runs and protects the nation's largest city at a time when the former president has threatened to deploy military troops to the city.

Against that backdrop, New York has experienced a mayoral election that has pitted two distinctly opposing Democrats against one another. The election has become an acrimonious face-off, marked by alleged racial bias and Islamophobia, but it is the political differences between the two leading candidates that could have major implications for how the party performs in next year's midterm elections.

The Progressive Challenger

In the progressive corner is the democratic socialist, the 34-year-old democratic socialist whose rapid ascent and people-powered movement has attracted international attention. On the establishment side is Andrew Cuomo, the ex- New York governor now campaigning independently – and enjoying the backing of wealthy contributors and big business.

As the election approaches, it is Mamdani, the former longshot who defeated Cuomo in the Democratic primary who is firmly installed as the frontrunner. Mamdani, who has campaigned on a platform of economic justice and pledged to freeze rent for about 2 million city residents, 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 resigned as governor in recent years amid accusations of misconduct, has stated clearly he will fight to the finish, and not necessarily in an above-the-belt manner. He has criticized his opponent's objectives as unrealistic, and in recent days chuckled along as a radio host made anti-Muslim comments about the candidate, who is Muslim. Recently, Cuomo was widely condemned as racist after posting an AI-generated ad that featured a slew of racial caricatures and showed his opponent freeing a convicts.

This represents a particularly ugly end to an race that could be critical to the path that the Democratic party, floundering in its reaction to the former president's authoritarian grabs, adopts in the coming years.

Broader Consequences

Should Mamdani secures a clear victory, the party establishment who have declined to support his campaign will be compelled to address a message that has resonated with voters' anger at inequality, soaring price rises and the establishment. It would be difficult for Chuck Schumer and Hakeem Jeffries not to adopt at least a portion of Mamdani's ambitious ideas about affordability, given the fresh face has generated an excitement within the party perhaps not seen since Bernie Sanders ran for president in 2016.

Conversely, if Cuomo, who had been predicted to sail to victory in the June primary, complete a surprising comeback win, it could reinforce the party's existing approach of cautious, lackluster resistance – a strategy that has infuriated grassroots members. A NYC rejection of Mamdani's progressive, positive message could persuade Schumer and Jeffries that the best plan is to stick to the center – even as polls show the current iteration of the Democratic party is widely disliked across the country.

Voter Enthusiasm

Residents of New York seem to prefer the Mamdani vision. Polls show that Mamdani supporters are far more enthusiastic about their choice than Cuomo backers, something that has been evident throughout the campaign. The candidate's snappy videos 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 supporters, many of them young or new participants.

Negative Tactics

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

Following extensive launching various attacks at Mamdani to see what might stick, the independent has narrowed his focus on attacking the candidate personally. He has labelled Mamdani, who was born in Uganda to South Asian heritage, an "radical", and appeared on conservative media for an interview with Maria Bartiromo, where Cuomo claimed the city “will not survive” Mamdani as mayor. It reached a nadir recently, when Cuomo laughed along and said “that’s another problem” after a radio host said Mamdani would “cheer” another terrorist attack.

Campaign Dynamics

This strategy echoes 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 Mamdani, and maybe that shouldn’t come as a surprise. A group of billionaire New Yorkers, including some who contributed to Trump in the 2024 election, have pumped millions into trying to elect Cuomo into office, as other powerful voices have urged Curtis Sliwa to drop out from the contest.

Candidate Backgrounds

As far as the his team, and his wealthy backers, are worried, it should not have reached to this point. When Mamdani, one of one hundred fifty New York state assembly members, started his campaign for mayor in October 2024, few had known him, and in reality, barely anyone even noticed.

The former governor, by comparison, eased his way into the contest in March 2025 and became the immediate frontrunner. He was the political heavyweight who apparently held all the advantages. 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, left office from the identical role.

Mamdani, who was voted in to the New York state assembly in recently, does not have the comparable background. But his dedication to providing no-cost transit and free childcare – along with the freeze-the-rent pledge – offer a more positive vision of the city's direction than Cuomo’s pessimistic predictions about “mayhem” and unfettered crime, and his promise to increase police presence.

Campaign Controversies

Still, Mamdani has encountered difficulties in the final phase, after footage surfaced appearing to show him suggesting the NYPD and the IDF were intertwined.

“We have to make clear that when the pressure of the police is on your throat, it’s been influenced by the IDF,” the candidate said in the clip, filmed at a Democratic Socialists of America convention in recent years. Mamdani, a vocal opponent of the Israeli government who has said the country is engaging in atrocities in the Palestinian territory, suggested he was questioning joint training exercises between the NYPD and Israeli forces.

Powerful Moment

With the election nearing, Mamdani seems to have gained empathy and backing, however, for his response to his opponent's increasing rhetoric.

Mamdani addressed the independent's terrorism comments 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 disclose about his religion. It was a lesson, Mamdani said, that many local Muslims 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 embrace their true selves, and that if we were to step out from those shadows, then it is in those silence that we must set aside our faith.”

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