New Yorkers will discover who will be their new city leader this election day, in a race that will determine who runs and protects the country's largest city at a time when Donald Trump has vowed to send military troops to the urban center.

Against that backdrop, New York has witnessed a race for mayor that has matched two very different Democratic figures against each other. The election has become an acrimonious face-off, marked by alleged racial bias and Islamophobia, but it is the ideological divide between the two leading candidates that could have major implications for how the party performs in next year's midterm elections.

The Progressive Challenger

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- New York governor now campaigning independently – and enjoying the backing of wealthy contributors and big business.

As the election approaches, it is Mamdani, the former longshot who defeated his opponent in the Democratic primary who is firmly installed as the frontrunner. Mamdani, who has run on a agenda of affordability and promised to freeze rent for about two million city residents, has led his rival by double-digits in every poll taken in October, and it is very much the progressive's race to lose.

A Bitter Contest

Yet, Cuomo, who stepped down as the state's leader in 2021 amid accusations of misconduct, has made it clear he will battle to the end, and not necessarily in an fair manner. He has trashed Mamdani's objectives as unachievable, and in the final stretch chuckled along as a radio host made anti-Muslim comments about the candidate, who is a Muslim. Two weeks ago, Cuomo was widely condemned as bigoted after sharing an AI-generated ad that featured a series of racist stereotypes and showed his opponent freeing a group of criminals.

It's been a rather grubby end to an race that could be critical to the direction that the party, struggling in its reaction to the former president's power moves, takes in the near future.

Broader Consequences

If the progressive secures a clear victory, the establishment party leaders who have refused to endorse his campaign will be compelled to address a message that has appealed to Americans' anger at economic disparity, soaring price rises and the political elite. It would be hard for Chuck Schumer and Hakeem Jeffries not to embrace at least a portion of Mamdani's ambitious ideas about affordability, given the fresh face has created an enthusiasm within the Democratic ranks arguably not seen since Bernie Sanders campaigned for the White House eight years ago.

Conversely, should Cuomo, who had been predicted to win easily in the Democratic primary, achieve a remarkable comeback win, it could reinforce national Democrats' current model of cautious, lackluster resistance – a strategy that has angered the party base. A New York rejection 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 nationwide.

Campaign Energy

Voters in New York seem to prefer the Mamdani vision. Polls show that Mamdani supporters are far more enthusiastic about their candidate than Cuomo backers, something that has been apparent during the race. The candidate's snappy videos on digital platforms, his optimistic vision for New York and his readiness to actually venture out and connect with voters in the city has attracted an army of more than 50,000 volunteers, many of them youth or first-time voters.

Negative Tactics

However, Cuomo, 67, isn't giving up. And with the risks stacked against him, the former governor has turned to negative campaigning in the final days.

After spending months throwing basically everything at Mamdani to see what might resonate, Cuomo has concentrated on attacking Mamdani directly. He has called his rival, who was born in Uganda to Indian parents, an “extremist”, and appeared on conservative media for an discussion with Maria Bartiromo, where the candidate claimed New York “will not survive” Mamdani as mayor. It hit bottom last week, when Cuomo laughed along and said “that’s another problem” after a radio host said the candidate would “cheer” another terrorist incident.

Campaign Dynamics

The line of attack mirrors much of what Trump, who has deployed the national guard to the capital and threatened to take similar action to NYC, has said about Mamdani, and perhaps that shouldn’t come as a surprise. A group of wealthy residents, including some who contributed to the Republican in the 2024 election, have invested heavily into trying to elect the independent elected, as other influential figures have urged Curtis Sliwa to drop out from the contest.

Candidate Backgrounds

For the Cuomo camp, and his wealthy backers, are concerned, it should never have come to this. When Mamdani, one of 150 New York state assembly members, launched his campaign for mayor in last year, few had heard of him, and in reality, few even paid attention.

Cuomo, by contrast, eased his way into the race 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 political dynasty member and served in a Democratic presidency. He became 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 New York state assembly in 2020, does not have the same political heritage. But his dedication to providing no-cost transit and affordable child services – along with the freeze-the-rent pledge – present a more positive vision of the future than Cuomo’s dire warnings about “mayhem” and rising criminal activity, and his promise to hire more police officers.

Recent Challenges

Still, the candidate has faced some challenges in the final phase, after video surfaced suggesting him suggesting the NYPD and the Israel Defense Forces were connected.

“We have to make clear that when the pressure of the police is on your neck, it’s been laced by the Israeli military,” the candidate said in the clip, filmed at a Democratic Socialists of America gathering in recent years. Mamdani, a vocal opponent of Israel who has said the country is engaging in atrocities in the Palestinian territory, indicated he was criticizing joint training exercises between the city police and IDF.

Powerful Moment

With the election nearing, the candidate appears to have won empathy and backing, however, for his response to his opponent's increasing rhetoric.

The progressive addressed the independent's terrorism comments in an heartfelt recording. In it, the candidate recalled how, when he first campaigned for the legislature, a Muslim uncle advised to him that he did not have to tell people about his religion. It was a lesson, Mamdani said, that many local Muslims had been taught “again and again”: “That safety could only be found in the shadows of our city. That it is in those hidden spaces alone where Muslims could embrace their full identities, and that if we were to step out from those shadows, then it is in those shadows that we must leave our faith.”

Addressing the behavior of Cuomo and Sliwa, who has alleged Mamd
