Residents of the Big Apple will discover the identity of their new city leader this election day, in a race that will decide who governs and defends the nation's largest city at a time when the former president has vowed to send armed forces to the urban center.

In this context, New York has experienced a mayoral election that has pitted two very different Democrats against one another. The election has become an increasingly bitter showdown, laced with accusations of racial bias and anti-Muslim sentiment, but it is the political differences between the two main candidates that could have major implications for how the party fares in next year's congressional races.

The Progressive Challenger

On the left side is the democratic socialist, the young democratic socialist whose meteoric rise and grassroots campaign has brought international attention. Representing the old guard is the former governor, the ex- New York governor now running as an independent – and benefiting from the support of wealthy contributors and big business.

As the election approaches, it is the progressive, the former longshot who defeated Cuomo in the Democratic primary who is firmly installed as the leading candidate. Mamdani, who has campaigned on a agenda of affordability and promised to halt rent increases for about 2 million city residents, has outpaced his rival by significant margins across all surveys taken in October, and it is very much the younger man's election to lose.

The Controversial Campaign

Yet, Cuomo, who stepped down as the state's leader in recent years amid accusations of sexual harassment, has made it clear he will battle to the end, and not necessarily in an fair manner. He has criticized Mamdani's objectives as unrealistic, and in recent days chuckled along as a radio host made anti-Muslim comments about Mamdani, 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 releasing 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 Trump's power moves, takes in the coming years.

Broader Consequences

If Mamdani secures a clear victory, the establishment party leaders who have declined to support his bid 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 the Senate leader and the House leader not to embrace at least a portion of the candidate's progressive proposals about affordability, given the fresh face has generated an excitement within the party arguably not witnessed since the Vermont senator ran for president in 2016.

However, should the former governor, who had been expected to win easily in the June primary, complete a surprising riches-to-rags-to-riches victory, it could reinforce national Democrats' existing approach of cautious, lackluster opposition – a tactic that has infuriated the party base. A NYC defeat of Mamdani's progressive, positive message could convince party leaders that the best plan is to stick to the political center – even as polls show the current iteration of the party is deeply unpopular nationwide.

Voter Enthusiasm

Residents of the city appear to favor the progressive agenda. Polls show that his backers are much more excited about their candidate than Cuomo backers, something that has been evident throughout the campaign. The candidate's snappy videos on social media, his optimistic vision for New York and his readiness to actually venture out and meet people in the metropolis has drawn an army of more than 50,000 supporters, many of them young or new participants.

Personal Attacks

Yet, the former governor, 67, continues to fight. And with the risks stacked against him, the former governor has resorted 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 attacking Mamdani personally. He has called his rival, who was born in Uganda to Indian parents, an "radical", and popped up on conservative media for an interview with a rightwing host, where the candidate asserted New York “will not survive” his opponent as city leader. It reached a nadir recently, when the former governor chuckled and said “that’s another problem” after a radio host said Mamdani would “cheer” another terrorist attack.

Campaign Dynamics

The line of attack echoes much of what Trump, who has sent the national guard to the capital and warned to do the same to New York, has said about Mamdani, and maybe that shouldn’t come as a surprise. A group of wealthy residents, including some who donated to the Republican in the 2024 election, have invested heavily into trying to get the independent elected, as other influential figures have pressured the Republican candidate to drop out from the race.

Political Histories

As far as the his team, and his wealthy backers, are concerned, it should not have reached to this point. When the assemblyman, one of 150 New York state assembly members, launched his mayoral bid in October 2024, not many had heard of him, and in reality, few even noticed.

The former governor, by comparison, eased his way into the contest in March 2025 and became the instant favorite. He was the big beast who apparently held every edge. The quintessential political insider, he had married a Kennedy and served in a Democratic presidency. He assumed office as New York governor in over a decade ago, seventeen years after his parent, Mario Cuomo, stepped down from the same position.

Mamdani, who was voted in to the state legislature in 2020, does not have the same political heritage. But his commitment to providing no-cost transit and free childcare – along with the rent control promise – present a brighter outlook of the city's direction than his opponent's dire warnings about “mayhem” and unfettered crime, and his promise to increase police presence.

Recent Challenges

Still, Mamdani has faced some challenges in recent days, after footage emerged suggesting him implying the New York police department and the IDF were connected.

“We have to make clear that when the pressure of the NYPD is on your neck, it’s been laced by the IDF,” the candidate said in the recording, filmed at a DSA gathering in 2023. The progressive, a vocal opponent of Israel who has said the nation is engaging in atrocities in the Palestinian territory, suggested he was criticizing joint training exercises between the NYPD and Israeli forces.

Powerful Moment

As the race closes, Mamdani appears to have won empathy and backing, however, for his response to his opponent's increasing rhetoric.

Mamdani responded to the independent's terrorism comments in an heartfelt recording. In it, the candidate remembered how, when he first campaigned for state assembly, a Muslim uncle advised 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 security could only be found in the shadows of our city. That it is in those shadows alone where followers of Islam could embrace their true selves, and that if we were to step out from those seclusion, then it is in those shadows that we must set aside our beliefs.”

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