New Yorkers will discover who will be their new city leader this Tuesday, in a contest that will determine who governs and protects the nation's largest city at a time when the former president has threatened to send armed forces to the urban center.

Against that backdrop, New York has experienced a race for mayor that has matched two very different Democrats against one another. The contest has become an acrimonious face-off, laced with accusations of racial bias and Islamophobia, but it is the political differences between the two leading contenders that could have major implications for how the party fares in next year's midterm elections.

The Progressive Challenger

In the progressive corner is the democratic socialist, the young democratic socialist whose rapid ascent and grassroots campaign has brought global notice. Representing the old guard is Andrew Cuomo, the ex- New York governor now running as an independent – and enjoying the support of wealthy contributors and big business.

With days to go, it is Mamdani, the one-time underdog who beat his opponent in the party primary who is solidly positioned as the frontrunner. The candidate, who has run on a platform of affordability and promised to freeze rent for about 2 million city residents, has outpaced his rival by significant margins in every poll taken in the fall, and it is very much the progressive's election to lose.

The Controversial Campaign

However, Cuomo, who resigned as the state's leader in 2021 amid accusations of sexual harassment, has stated clearly he will battle to the end, and not necessarily in an above-the-belt fashion. He has criticized his opponent's goals as unrealistic, and in recent days laughed as a radio host made Islamophobic remarks about the candidate, who is Muslim. Two weeks ago, Cuomo was widely condemned as racist after sharing an artificial intelligence video that included a slew of racist stereotypes and showed his opponent releasing a group of criminals.

This represents a particularly ugly end to an race that could be key to the direction that the Democratic party, struggling in its response to the former president's authoritarian grabs, takes in the near future.

Broader Consequences

If the progressive wins convincingly, the party establishment who have declined to support his bid will be forced to reckon with a message that has appealed to voters' anger at economic disparity, soaring price rises and the establishment. It would be difficult for Chuck Schumer and the House leader not to embrace at least some of Mamdani's ambitious ideas about economic justice, given the fresh face has generated an excitement within the Democratic ranks perhaps not witnessed since the Vermont senator campaigned for the White House in 2016.

However, if Cuomo, who had been expected to sail to victory in the Democratic primary, achieve a surprising riches-to-rags-to-riches victory, it could reinforce national Democrats' existing approach of considered, lackluster resistance – a tactic that has infuriated grassroots members. A NYC defeat of the progressive's progressive, positive message could convince Schumer and Jeffries that the best plan is to remain in the political center – even as polls show the current iteration of the Democratic party is widely disliked nationwide.

Campaign Energy

Voters in New York seem to prefer the Mamdani vision. Surveys show that Mamdani supporters are far more enthusiastic 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 the city and his willingness to actually venture out and meet people in the metropolis has attracted an force 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 stakes against him, the ex-leader has turned to negative campaigning in recent weeks.

Following extensive launching various attacks at Mamdani to see what might resonate, Cuomo has concentrated on attacking Mamdani personally. He has labelled Mamdani, who was of Ugandan origin to Indian parents, an “extremist”, and popped up on conservative media for an interview with a rightwing host, where Cuomo asserted New York “will not survive” his opponent as mayor. It reached a nadir last week, when Cuomo chuckled and said “that’s another problem” after a radio host said the candidate would “cheer” another terrorist incident.

Campaign Dynamics

This strategy echoes much of what the former president, who has deployed the national guard to Washington DC and threatened to do the same to NYC, has said about Mamdani, and maybe that shouldn’t come as a surprise. A group of wealthy residents, including some who contributed to Trump in the 2024 election, have pumped millions into trying to elect Cuomo into office, as other influential figures have pressured the Republican candidate to drop out from the contest.

Political Histories

For the Cuomo camp, and his wealthy backers, are worried, it should never have come to this point. When the assemblyman, one of 150 state legislators, launched his campaign for mayor in October 2024, few had heard of him, and in truth, barely anyone even paid attention.

Cuomo, by comparison, entered smoothly into the race in March 2025 and became the immediate frontrunner. He was the big beast who seemingly held all the advantages. The classic political insider, he had married a political dynasty member and worked in Bill Clinton’s administration. He became New York governor in over a decade ago, 17 years after his father, Mario Cuomo, left office from the same position.

The progressive, who was voted in to the New York state assembly in recently, 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 Cuomo’s pessimistic predictions about “mayhem” and unfettered crime, and his promise to increase police presence.

Recent Challenges

Nevertheless, Mamdani has encountered some challenges in the final phase, after video emerged appearing to show him implying the New York police department and the IDF were connected.

“We have to make clear that when the pressure of the police is on your throat, it’s been laced by the IDF,” the candidate said in the recording, recorded at a DSA convention in recent years. Mamdani, a longtime critic of Israel who has said the nation is committing genocide in the Palestinian territory, indicated he was questioning cooperative programs between the city police and IDF.

Powerful Moment

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

The progressive addressed Cuomo’s 9/11 remarks in an emotional video. In it, Mamdani recalled how, when he first campaigned for the legislature, a family member suggested to him that he did not have to disclose about his Muslim faith. It was a realization, Mamdani said, that many local Muslims had been taught “again and again”: “That safety could only be found in the shadows of our community. That it is in those hidden spaces alone where Muslims could express their true selves, and that if we were to step out from those seclusion, then it is in those shadows that we must set aside our beliefs.”

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