Residents of the Big Apple will learn who will be their next mayor this Tuesday, in a race that will determine who governs and defends the country's most populous metropolis at a moment when the former president has threatened to send military troops to the urban center.

Against that backdrop, New York has experienced a race for mayor that has matched two very different Democratic figures against one another. The election has turned into an acrimonious showdown, laced with accusations of racial bias and anti-Muslim sentiment, but it is the ideological divide between the two main candidates that could have major implications for how the Democratic party performs in next year's midterm elections.

The Progressive Challenger

On the left side is the democratic socialist, the young democratic socialist whose meteoric rise and people-powered movement has brought international attention. On the establishment side is the former governor, the former New York governor now running as an independent – and enjoying the support of ultra-rich donors and corporations.

As the election approaches, it is the progressive, the one-time underdog who beat Cuomo in the party primary who is firmly installed as the leading candidate. Mamdani, who has run on a platform of affordability and pledged to freeze rent for about 2 million city residents, has led Cuomo by significant margins across all surveys conducted in the fall, and it is very much the younger man's election to lose.

The Controversial Campaign

Yet, the former governor, who stepped down as the state's leader in 2021 amid accusations of sexual harassment, has made it clear he will battle to the finish, and not necessarily in an fair fashion. He has criticized Mamdani's objectives as unachievable, and in recent days laughed as a radio host made Islamophobic remarks about the candidate, who is a Muslim. Two weeks ago, the independent was widely condemned as bigoted after posting an AI-generated ad that featured a series of racial caricatures and showed Mamdani releasing a convicts.

This represents a rather grubby end to an election that could be key to the path that the party, struggling in its reaction to Trump's power moves, adopts in the near future.

National Implications

Should Mamdani wins convincingly, the party establishment who have refused to endorse his campaign will be forced to reckon with a message that has resonated with voters' anger at inequality, inflation and the political elite. It would be difficult for the Senate leader and Hakeem Jeffries not to adopt at least a portion of Mamdani's progressive proposals about economic justice, given the newcomer has generated an excitement within the party perhaps not witnessed since Bernie Sanders ran for president eight years ago.

However, if Cuomo, who had been expected to win easily in the Democratic primary, achieve a surprising riches-to-rags-to-riches victory, it could cement the party's current model of cautious, lackluster opposition – a strategy that has infuriated the party base. A New York defeat of the progressive's progressive, positive message could persuade party leaders that the wisest course is to remain in the political center – even as surveys show the current iteration of the Democratic party is deeply unpopular across the country.

Campaign Energy

Residents of the city seem to prefer the progressive agenda. Polls show that his backers are far more enthusiastic about their candidate than his opponent's supporters, something that has been evident throughout the campaign. Mamdani's engaging content on social media, his hopeful outlook for the city and his readiness to actually get out and connect with voters in the city has attracted an force of over fifty thousand volunteers, many of them young or new participants.

Personal Attacks

However, Cuomo, 67, continues to fight. And with the stakes stacked against him, the ex-leader has resorted to ugly messaging in the final days.

Following extensive throwing basically everything at Mamdani to see what might resonate, the independent has narrowed his focus on targeting Mamdani directly. He has called Mamdani, who was born in Uganda to South Asian heritage, an “extremist”, and popped up on Fox Business for an interview with a rightwing host, where Cuomo claimed New York “will not survive” his opponent as mayor. It reached a nadir recently, when the former governor chuckled and said “that’s another problem” after a broadcaster said the candidate would “cheer” another terrorist incident.

Political Landscape

This strategy echoes much of what the former president, who has sent the military reserves to the capital and warned to do the same to NYC, has said about Mamdani, and maybe that is expected. A group of wealthy residents, including some who donated to Trump in the 2024 election, have pumped millions into trying to elect Cuomo elected, as other powerful voices have urged the Republican candidate to withdraw from the race.

Political Histories

For the his team, and his billionaire supporters, are concerned, it should never have come to this point. When Mamdani, one of one hundred fifty state legislators, launched his campaign for mayor in last year, few had known him, and in reality, barely anyone even paid attention.

Cuomo, by contrast, eased his way into the contest in March 2025 and became the instant favorite. He was the political heavyweight who apparently held every edge. The quintessential political insider, he had married a Kennedy and served in Bill Clinton’s administration. He assumed office as New York governor in 2011, seventeen years after his parent, Mario Cuomo, stepped down from the same position.

The progressive, who was elected to the state legislature in 2020, does not have the comparable background. But his dedication to providing free buses and affordable child services – along with the freeze-the-rent pledge – present a brighter outlook of the city's direction than Cuomo’s dire warnings about “mayhem” and unfettered crime, and his promise to increase police presence.

Recent Challenges

Still, the candidate has faced difficulties in the final phase, after video surfaced suggesting him suggesting the New York police department and the IDF were intertwined.

“We have to make clear that when the pressure of the NYPD is on your neck, it’s been laced by the Israeli military,” the candidate said in the recording, filmed at a Democratic Socialists of America gathering in 2023. Mamdani, a longtime critic of the Israeli government who has said the country is engaging in atrocities in the Palestinian territory, indicated 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.

The progressive addressed the independent's terrorism comments in an emotional video. In it, Mamdani recalled how, when he first ran for state assembly, a Muslim uncle suggested to him that he did not have to disclose about his religion. It was a realization, Mamdani said, that many Muslim New Yorkers had been told “again and again”: “That safety could only be found in the margins 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 step out from those shadows, then it is in those silence that we must set aside our faith.”

Speaking to the behavior of Cuomo and Sliwa, who has claimed Mamd
