New Yorkers will learn the identity of their next mayor this election day, in a contest that will decide who runs and protects the nation's most populous metropolis at a moment when Donald Trump has threatened to deploy military troops to the city.

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 showdown, marked by accusations of racial bias and Islamophobia, but it is the ideological divide between the two leading candidates that could have significant consequences for how the party performs in next year's congressional races.

The Rising Progressive

In the progressive corner is the democratic socialist, the young progressive candidate whose rapid ascent and grassroots campaign has brought international attention. Representing the old guard is the former governor, the former New York governor now campaigning independently – and benefiting from the backing of wealthy contributors and corporations.

With days to go, it is Mamdani, the former longshot who defeated his opponent in the Democratic primary who is solidly positioned as the leading candidate. Mamdani, who has campaigned on a platform of affordability and pledged to halt rent increases for about 2 million New Yorkers, has outpaced Cuomo by significant margins across all surveys taken in the fall, and it is very much the younger man's election to throw away.

A Bitter Contest

However, the former governor, who stepped down as governor in 2021 amid accusations of sexual harassment, has stated clearly he will fight to the end, and not necessarily in an above-the-belt fashion. He has criticized his opponent's objectives as unrealistic, and in the final stretch laughed as a broadcaster made anti-Muslim comments about the candidate, who is a Muslim. Two weeks ago, the independent was strongly criticized as bigoted after sharing an artificial intelligence video that included a slew of racial caricatures and showed Mamdani freeing a convicts.

This represents a rather grubby conclusion to an race that could be key to the path that the party, struggling in its response to Trump's authoritarian grabs, 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 forced to reckon with a message that has appealed to Americans' frustration at inequality, soaring price rises and the establishment. It would be hard for the Senate leader and Hakeem Jeffries not to embrace at least some of Mamdani's ambitious ideas about economic justice, given the newcomer has created an enthusiasm within the party arguably not witnessed since Bernie Sanders ran for president in 2016.

However, if Cuomo, who had been predicted to win easily in the Democratic primary, complete a surprising riches-to-rags-to-riches victory, it could cement national Democrats' existing approach of cautious, uninspiring resistance – a strategy that has angered grassroots members. A NYC rejection of Mamdani's progressive, positive message could persuade Schumer and Jeffries that the best plan is to remain in the center – even as polls show the current iteration of the party is deeply unpopular across the country.

Campaign Energy

Residents of New York appear to favor the progressive agenda. Polls show that his backers are far more enthusiastic about their candidate than Cuomo backers, something that has been apparent throughout the campaign. The candidate's snappy videos on digital platforms, his hopeful outlook for the city and his readiness to actually venture out and connect with voters in the city has drawn an force of more than 50,000 volunteers, many of them young or first-time voters.

Personal Attacks

However, Cuomo, 67, isn't giving up. And with the risks against him, the ex-leader has resorted to negative campaigning in the final days.

After spending months throwing basically everything at Mamdani to see what might stick, the independent has concentrated on attacking the candidate personally. He has called his rival, who was born in Uganda to Indian parents, an "radical", and popped up on conservative media for an discussion with Maria Bartiromo, where the candidate asserted the city “will not survive” his opponent as city leader. It reached a nadir recently, when Cuomo laughed along and said “that’s another problem” after a radio host said Mamdani would “cheer” another 9/11-style incident.

Political Landscape

The line of attack echoes much of what Trump, who has sent the national guard to the capital and threatened to take similar action to New York, has said about the progressive, and perhaps that shouldn’t come as a surprise. A group of wealthy residents, including some who contributed to Trump in the last presidential race, have pumped millions into trying to get the independent into office, as other influential figures have pressured the Republican candidate to withdraw from the race.

Political Histories

For the his team, and his billionaire supporters, are worried, it should not have reached to this point. When the assemblyman, one of 150 state legislators, started his mayoral bid in October 2024, not many had heard of him, and in reality, few even noticed.

Cuomo, by comparison, eased his way into the race in March 2025 and became the instant favorite. He was the political heavyweight who seemingly held every edge. The quintessential establishment figure, he had wed a political dynasty member and worked in Bill Clinton’s administration. He became New York governor in 2011, seventeen years after his father, Mario Cuomo, stepped down from the identical role.

The progressive, who was elected to the New York state assembly in recently, does not have the comparable background. But his dedication to providing no-cost transit and free childcare – along with the freeze-the-rent pledge – offer a brighter outlook of the future than his opponent's dire warnings about “mayhem” and unfettered crime, and his promise to increase police presence.

Campaign Controversies

Nevertheless, Mamdani has faced some challenges in the final phase, after video emerged appearing to show him implying the NYPD and the Israel Defense Forces were intertwined.

“We have to make clear that when the boot of the NYPD is on your neck, it’s been influenced by the Israeli military,” the candidate said in the clip, filmed at a DSA convention in recent years. The progressive, a longtime critic 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

With the election nearing, the candidate appears to have won sympathy and support, however, for his reaction to his opponent's escalating attacks.

The progressive responded to Cuomo’s 9/11 remarks in an emotional video. In it, the candidate remembered how, when he first ran for the legislature, a family member suggested to him that he did not have to disclose about his Muslim faith. It was a lesson, he 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 Muslims could express their true selves, and that if we were to emerge from those seclusion, then it is in those silence that we must leave our beliefs.”

Speaking to the actions of his opponents, who has alleged Mamd
