Residents of the Big Apple will discover the identity of their next mayor this election day, in a race that will decide who governs and defends the nation's largest city at a moment when Donald Trump has threatened to deploy armed forces to the city.

Against that backdrop, New York has witnessed a race for mayor that has matched two very different Democrats against each other. The contest has become an acrimonious showdown, laced with accusations of racism 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 congressional races.

The Rising Progressive

On the left side is the democratic socialist, the 34-year-old progressive candidate whose meteoric rise and people-powered movement has brought global notice. On the establishment side is Andrew Cuomo, the former 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 Mamdani, the former longshot who beat his opponent in the party primary who is solidly positioned as the leading candidate. The candidate, who has campaigned on a platform of affordability and promised to halt rent increases for about 2 million city residents, has outpaced his rival by double-digits across all surveys conducted in the fall, and it is very much the progressive's race to lose.

The Controversial Campaign

Yet, Cuomo, who resigned as the state's leader in 2021 amid allegations of sexual harassment, has stated clearly he will battle to the finish, and not necessarily in an fair fashion. He has criticized his opponent's goals as unrealistic, and in recent days chuckled along as a radio host made anti-Muslim comments about Mamdani, who is a Muslim. Recently, Cuomo was strongly criticized as racist after posting an artificial intelligence video that featured a slew of racist stereotypes and showed his opponent releasing a convicts.

It's been a particularly ugly end to an race that could be critical to the path that the party, struggling in its reaction to Trump's authoritarian grabs, takes in the coming years.

Broader Consequences

If the progressive secures a clear victory, the party establishment who have refused to endorse his bid will be compelled to address a message that has resonated with Americans' anger at economic disparity, inflation and the political elite. It would be hard for Chuck Schumer and the House leader not to adopt at least a portion of Mamdani's progressive proposals about economic justice, given the fresh face has generated an enthusiasm within the party perhaps not witnessed since Bernie Sanders campaigned for the White House in 2016.

However, if Cuomo, who had been expected to win easily in the June primary, complete a surprising riches-to-rags-to-riches win, it could reinforce the party's current model of considered, lackluster opposition – a strategy that has infuriated the party base. A NYC rejection of the progressive's optimistic platform could persuade party leaders that the wisest course is to stick to the political center – even as surveys show the current iteration of the Democratic party is widely disliked across the country.

Campaign Energy

Residents of New York seem to prefer the progressive agenda. Polls show that Mamdani supporters are far more enthusiastic about their choice than Cuomo backers, something that has been evident during the race. Mamdani's snappy videos on digital platforms, his hopeful outlook for the city and his willingness to actually venture out and connect with voters in the metropolis has drawn an force of more than 50,000 supporters, many of them young or first-time voters.

Negative Tactics

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

After spending months throwing basically everything at Mamdani to see what might stick, the independent has concentrated on attacking Mamdani personally. He has called his rival, who was born in Uganda to South Asian heritage, 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 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 mirrors 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 perhaps that shouldn’t come as a surprise. A set of billionaire New Yorkers, including some who contributed to the Republican in the 2024 election, have pumped millions into trying to get Cuomo into office, as other influential figures have pressured the Republican candidate to drop out from the contest.

Candidate Backgrounds

As far as the his team, and his wealthy backers, are concerned, it should never have come to this. When Mamdani, one of 150 state legislators, launched his campaign for mayor in October 2024, few 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 political heavyweight who seemingly held every edge. The quintessential establishment figure, he had married a Kennedy and served in Bill Clinton’s administration. He became New York governor in over a decade ago, seventeen years after his parent, the former governor, left office from the same position.

The progressive, who was voted in to the state legislature in 2020, does not have the same political heritage. 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 his opponent's dire warnings about “mayhem” and rising criminal activity, and his vow to hire more police officers.

Campaign Controversies

Still, Mamdani has faced some challenges in recent days, after footage emerged appearing to show him suggesting the NYPD and the Israel Defense Forces were intertwined.

“We have to make clear that when the boot of the NYPD is on your throat, it’s been influenced by the IDF,” the candidate said in the recording, recorded at a Democratic Socialists of America gathering in recent years. Mamdani, a vocal opponent of the Israeli government who has said the country is engaging in atrocities in the Palestinian territory, suggested he was questioning cooperative programs between the city police and Israeli forces.

Emotional Response

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

Mamdani responded to the independent's 9/11 remarks in an heartfelt recording. In it, Mamdani recalled how, when he first campaigned for the legislature, a family member suggested to him that he did not have to disclose about his religion. It was a lesson, he 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 shadows alone where followers of Islam could express their true selves, and that if we were to emerge from those shadows, then it is in those silence that we must set aside our beliefs.”
