Residents of the Big Apple will find out who will be their new city leader this Tuesday, in a contest that will determine who runs and defends the nation's largest city at a time when Donald Trump has vowed to send armed forces to the city.

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

The Rising Progressive

In the progressive corner is the democratic socialist, the young democratic socialist whose rapid ascent and grassroots campaign has attracted global notice. On the establishment side is Andrew Cuomo, the ex- New York governor now running as an independent – and benefiting from the support of wealthy contributors and corporations.

With days to go, 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 affordability and promised to halt rent increases for about two 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 throw away.

The Controversial Campaign

However, Cuomo, who stepped down as governor in 2021 amid allegations of sexual harassment, has stated clearly he will battle to the end, and not necessarily in an above-the-belt manner. He has criticized Mamdani's objectives as unachievable, and in recent days chuckled along as a broadcaster made anti-Muslim comments about Mamdani, who is a Muslim. Two weeks ago, Cuomo was strongly criticized as racist after sharing an artificial intelligence video that included a slew of racial caricatures and showed his opponent freeing a group of criminals.

This represents a rather grubby conclusion to an race that could be critical to the direction that the party, struggling in its response to the former president's authoritarian grabs, takes in the coming years.

National Implications

Should the progressive secures a clear victory, the establishment party leaders who have declined to support his campaign will be forced to reckon with a message that has resonated with voters' anger at economic disparity, inflation and the establishment. It would be hard for the Senate leader and the House leader not to adopt at least a portion of Mamdani's progressive proposals about affordability, given the fresh face has generated an enthusiasm within the party arguably not witnessed since Bernie Sanders campaigned for the White House eight years ago.

Conversely, should the former governor, who had been predicted to sail to victory in the Democratic primary, complete a surprising riches-to-rags-to-riches win, it could reinforce the party's current model of considered, uninspiring opposition – a tactic that has infuriated grassroots members. A New York defeat of Mamdani's progressive, positive message could persuade Schumer and Jeffries that the best plan is to remain in the center – even as polls show the present version of the Democratic party is widely disliked across the country.

Campaign Energy

Residents of New York appear to favor the Mamdani vision. Surveys show that Mamdani supporters are much more excited about their candidate than his opponent's supporters, something that has been apparent throughout the campaign. The candidate's snappy videos on social media, his hopeful outlook for the city and his readiness to actually get out and meet people in the city has drawn an army of more than 50,000 supporters, many of them young or first-time voters.

Personal Attacks

Yet, the former governor, 67, isn't giving up. And with the stakes stacked against him, the ex-leader has turned to ugly messaging in the final days.

After spending months launching various attacks at his opponent to see what might stick, Cuomo has concentrated on targeting Mamdani personally. He has called his rival, who was of Ugandan origin to Indian parents, an “extremist”, and popped up on conservative media for an interview with Maria Bartiromo, where the candidate claimed the city “will not survive” his opponent as city leader. It reached a nadir recently, when Cuomo chuckled and said “that’s another problem” after a broadcaster said the candidate would “cheer” another terrorist incident.

Campaign Dynamics

This strategy echoes much of what the former president, who has deployed the military reserves to the capital and threatened to do the same to New York, has said about Mamdani, and perhaps that is expected. A set of wealthy residents, including some who donated to Trump in the last presidential race, have invested heavily into trying to get the independent into office, as other influential figures have urged the Republican candidate to withdraw from the race.

Political Histories

For the Cuomo camp, and his billionaire supporters, are worried, it should not have reached to this. When the assemblyman, one of 150 New York state assembly members, launched his mayoral bid in October 2024, few had known him, and in truth, few even paid attention.

Cuomo, by contrast, entered smoothly into the contest in March 2025 and became the instant favorite. He was the political heavyweight who apparently held every edge. The quintessential establishment figure, he had wed a Kennedy and served in Bill Clinton’s administration. He assumed office as the state's leader in 2011, seventeen years after his parent, Mario Cuomo, left office from the identical role.

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 freeze-the-rent pledge – offer a brighter outlook of the city's direction than his opponent's pessimistic predictions about “mayhem” and unfettered crime, and his promise to hire more police officers.

Recent Challenges

Nevertheless, Mamdani has encountered some challenges in the final phase, after video emerged suggesting him implying the NYPD and the Israel Defense Forces were connected.

“We have to make clear that when the boot of the police is on your neck, it’s been influenced by the IDF,” Mamdani said in the clip, recorded at a DSA gathering in 2023. Mamdani, a longtime critic of Israel who has said the nation is engaging in atrocities in Gaza, indicated he was questioning cooperative programs between the city police and Israeli forces.

Powerful Moment

With the election nearing, Mamdani appears to have won empathy and backing, however, for his response to his opponent's escalating attacks.

The progressive responded to Cuomo’s 9/11 remarks in an heartfelt recording. In it, the candidate recalled how, when he first ran for the legislature, a Muslim uncle advised to him that he did not have to tell people about his Muslim faith. It was a realization, he said, that many Muslim New Yorkers had been taught “again and again”: “That security 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 emerge from those seclusion, then it is in those shadows that we must leave our faith.”

Addressing the actions of his opponents, who has alleged Mamd
