New Yorkers will discover who will be their new city leader this Tuesday, in a race that will determine who governs and protects the nation's most populous metropolis at a time when Donald Trump has threatened to deploy armed forces to the city.

In this context, New York has witnessed a race for mayor that has pitted two very different Democratic figures against each other. The contest has become an acrimonious face-off, marked by alleged racial bias and anti-Muslim sentiment, but it is the political differences between the two main candidates that could have significant consequences for how the party performs in next year's midterm elections.

The Rising Progressive

In the progressive corner is the democratic socialist, the young democratic socialist whose meteoric rise and grassroots campaign has attracted global notice. Representing the old guard is Andrew Cuomo, the ex- Democratic New York governor now running as an independent – and benefiting from the backing of ultra-rich donors and big business.

With days to go, it is Mamdani, the former longshot who beat his opponent in the party primary who is solidly positioned as the frontrunner. The candidate, who has run on a agenda of economic justice and promised to halt rent increases for about 2 million city residents, has outpaced Cuomo by double-digits across all surveys conducted in October, and it is very much the progressive's election to throw away.

The Controversial Campaign

Yet, the former governor, who resigned as the state's leader in recent years amid accusations of sexual harassment, has made it clear he will fight to the end, and not necessarily in an above-the-belt fashion. He has trashed Mamdani's objectives as unachievable, and in recent days chuckled along as a broadcaster made Islamophobic remarks about Mamdani, who is a Muslim. Recently, Cuomo was strongly criticized as racist after posting an artificial intelligence video that included a slew of racial caricatures and showed his opponent freeing a convicts.

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

Broader Consequences

Should Mamdani secures a clear victory, the party establishment who have refused to endorse his campaign will be forced to reckon with a platform that has resonated with Americans' anger at economic disparity, soaring price rises and the establishment. It would be hard 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 Bernie Sanders ran for president in 2016.

However, if Cuomo, who had been predicted to sail to victory in the Democratic primary, complete a surprising comeback win, it could reinforce the party's current model of cautious, lackluster resistance – a tactic that has angered grassroots members. A New York rejection of the progressive's optimistic platform could convince Schumer and Jeffries that the best plan is to stick to the political center – even as polls show the current iteration of the party is widely disliked nationwide.

Campaign Energy

Voters in the city appear to favor the Mamdani vision. Polls show that Mamdani supporters are much more excited about their choice than his opponent's supporters, something that has been evident throughout the campaign. Mamdani's snappy videos on digital platforms, his optimistic vision for the city and his readiness 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 first-time voters.

Negative Tactics

However, the former governor, in his late sixties, continues to fight. And with the stakes stacked against him, the former governor has resorted to negative campaigning in recent weeks.

Following extensive launching various attacks at Mamdani to see what might resonate, Cuomo has narrowed his focus on attacking Mamdani directly. He has labelled his rival, who was born in Uganda to South Asian heritage, an “extremist”, and appeared on Fox Business for an discussion with a rightwing host, where the candidate claimed the city “will not survive” Mamdani as city leader. It reached a nadir last week, when Cuomo laughed along and said “that’s another problem” after a broadcaster said Mamdani would “cheer” another 9/11-style incident.

Campaign Dynamics

This strategy echoes much of what the former president, who has sent the national guard to Washington DC and warned to do the same to NYC, has said about Mamdani, and maybe that shouldn’t come as a surprise. A set of wealthy residents, including some who donated to Trump in the last presidential race, have invested heavily into trying to elect Cuomo into office, as other powerful voices have pressured Curtis Sliwa to drop out from the race.

Candidate Backgrounds

For the Cuomo camp, and his billionaire supporters, are worried, it should never have come to this point. When Mamdani, one of one hundred fifty state legislators, started his mayoral bid in October 2024, few had heard of him, and in reality, few even paid attention.

Cuomo, by comparison, entered smoothly into the contest in March 2025 and became the immediate frontrunner. He was the political heavyweight who apparently held every edge. The quintessential political insider, he had wed a political dynasty member and served in Bill Clinton’s administration. He assumed office as the state's leader in over a decade ago, seventeen years after his father, Mario Cuomo, left office from the same position.

Mamdani, who was elected to the state legislature in 2020, does not have the comparable background. But his commitment to providing free buses and affordable child services – along with the rent control promise – offer a brighter outlook of the future than his opponent's pessimistic predictions about “mayhem” and unfettered crime, and his vow to increase police presence.

Recent Challenges

Nevertheless, Mamdani has faced some challenges in the final phase, after footage surfaced suggesting him suggesting the New York police department and the Israel Defense Forces were connected.

“We have to make clear that when the boot of the police is on your throat, it’s been influenced by the Israeli military,” the candidate said in the clip, filmed at a Democratic Socialists of America convention in 2023. The progressive, a longtime critic of the Israeli government who has said the country is engaging in atrocities in Gaza, suggested he was questioning joint training exercises between the NYPD and Israeli forces.

Emotional Response

As the race closes, Mamdani seems to have gained sympathy and support, however, for his reaction to Cuomo’s increasing rhetoric.

Mamdani addressed the independent's terrorism comments in an emotional video. In it, the candidate remembered how, when he first ran for the legislature, a family member suggested to him that he did not have to tell people about his Muslim faith. It was a realization, he 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 hidden spaces alone where Muslims could embrace their true selves, and that if we were to emerge from those shadows, then it is in those shadows that we must set aside our beliefs.”

Addressing the behavior of his opponents, who has alleged Mamd
