New Yorkers will learn who will be their next mayor this Tuesday, in a race that will determine who runs and defends the country's most populous metropolis at a moment when the former president has vowed to send military troops to the urban center.

In this context, New York has experienced a race for mayor that has matched two very different Democratic figures against one another. The election has become an increasingly bitter face-off, marked by alleged racism and anti-Muslim sentiment, but it is the political differences between the two leading candidates that could have major implications for how the party fares in next year's congressional races.

The Progressive Challenger

In the progressive corner is the democratic socialist, the young progressive candidate whose meteoric rise and grassroots campaign has attracted global notice. On the establishment side is Andrew Cuomo, the ex- Democratic New York governor now campaigning independently – and benefiting from the backing of wealthy contributors and corporations.

With days to go, it is the progressive, the one-time underdog who beat Cuomo in the party primary who is firmly installed as the frontrunner. Mamdani, who has campaigned on a platform of economic justice and promised to halt rent increases for about two million New Yorkers, has outpaced Cuomo by double-digits in every poll conducted in the fall, and it is very much the younger man's race to throw away.

The Controversial Campaign

Yet, Cuomo, who resigned as the state's leader in recent years amid accusations of sexual harassment, has stated clearly he will fight to the end, and not necessarily in an above-the-belt manner. He has criticized Mamdani's goals as unrealistic, and in recent days laughed as a broadcaster made anti-Muslim comments about the candidate, who is a Muslim. Two weeks ago, Cuomo was widely condemned as racist after sharing an AI-generated ad that included a series of racial caricatures and showed Mamdani freeing a group of criminals.

It's been a particularly ugly conclusion to an race that could be critical to the path that the party, struggling in its response to the former president's authoritarian grabs, takes in the near future.

National Implications

Should Mamdani wins convincingly, the party establishment who have declined to support his campaign will be forced to reckon with a platform that has resonated with Americans' frustration at economic disparity, inflation and the political elite. It would be difficult for the Senate leader and Hakeem Jeffries not to adopt at least some of the candidate's ambitious ideas about affordability, given the newcomer has created an enthusiasm within the party perhaps not seen since the Vermont senator campaigned for the White House eight years ago.

Conversely, should the former governor, who had been expected to sail to victory in the Democratic primary, complete a remarkable comeback victory, it could reinforce the party's existing approach of cautious, lackluster resistance – a tactic that has infuriated the party base. A NYC rejection of Mamdani's optimistic platform could persuade party leaders that the wisest course is to remain in the center – even as polls show the present version of the party is deeply unpopular nationwide.

Campaign Energy

Residents of New York seem to prefer the progressive agenda. Surveys show that his backers are far more enthusiastic about their choice than his opponent's supporters, something that has been apparent throughout the campaign. Mamdani's engaging content on digital platforms, his hopeful outlook for the city and his willingness to actually get out and connect with voters in the metropolis has drawn an force of over fifty thousand volunteers, many of them youth or new participants.

Personal Attacks

Yet, Cuomo, 67, continues to fight. And with the stakes against him, the former governor has turned to ugly messaging in the final days.

Following extensive throwing basically everything at Mamdani to see what might stick, Cuomo has narrowed his focus on attacking Mamdani personally. He has labelled his rival, who was of Ugandan origin to Indian parents, an “extremist”, and appeared on Fox Business for an interview with Maria Bartiromo, where Cuomo claimed the city “will not survive” his opponent as city leader. It hit bottom last week, when Cuomo laughed along and said “that’s another problem” after a broadcaster said Mamdani would “cheer” another terrorist attack.

Political Landscape

The line of attack echoes much of what the former president, who has sent the national guard to Washington DC and threatened to take similar action to NYC, has said about the progressive, and perhaps that shouldn’t come as a surprise. A group of billionaire New Yorkers, including some who donated to the Republican in the last presidential race, have invested heavily into trying to get Cuomo into office, as other powerful voices have pressured the Republican candidate to drop out from the contest.

Political Histories

For the his team, and his billionaire supporters, are concerned, it should not have reached to this point. When the assemblyman, one of 150 state legislators, launched his mayoral bid in last year, few had heard of him, and in truth, barely anyone even noticed.

Cuomo, by contrast, entered smoothly into the contest in March 2025 and became the instant favorite. He was the big beast who apparently held all the advantages. The quintessential political insider, he had married a Kennedy and served in a Democratic presidency. He assumed office as New York governor in 2011, 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 commitment to providing free buses and free childcare – along with the freeze-the-rent pledge – present a more positive vision of the city's direction than his opponent's dire warnings about “mayhem” and unfettered crime, and his promise to hire more police officers.

Recent Challenges

Nevertheless, Mamdani has encountered difficulties in recent days, after footage surfaced appearing to show him implying the NYPD and the Israel Defense Forces were intertwined.

“We have to make clear that when the pressure of the NYPD is on your throat, it’s been laced by the IDF,” the candidate said in the recording, recorded at a Democratic Socialists of America gathering in 2023. Mamdani, a vocal opponent of Israel who has said the nation is engaging in atrocities in Gaza, indicated he was questioning joint training exercises between the city police and Israeli forces.

Powerful Moment

With the election nearing, Mamdani seems to have gained empathy and backing, however, for his response to Cuomo’s escalating attacks.

Mamdani addressed the independent's 9/11 remarks in an emotional video. In it, Mamdani recalled 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 lesson, Mamdani said, that many local Muslims had been told “again and again”: “That security could only be found in the shadows of our city. That it is in those hidden spaces 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 set aside our beliefs.”
