New Yorkers will learn who will be their next mayor this Tuesday, in a contest that will determine who governs and defends the nation's most populous metropolis at a moment when Donald Trump has vowed to deploy military troops to the urban center.

In this context, New York has experienced a mayoral election that has matched two very different Democratic figures against each other. The election has turned into an acrimonious face-off, marked by accusations of racism and Islamophobia, but it is the political differences between the two main candidates that could have significant consequences for how the party fares in next year's congressional races.

The Progressive Challenger

On the left side is the democratic socialist, the young progressive candidate whose rapid ascent and people-powered movement has brought international attention. On the establishment side is Andrew Cuomo, the ex- Democratic New York governor now running as an independent – and benefiting from the backing of ultra-rich donors and big business.

With days to go, it is the progressive, the one-time underdog who defeated Cuomo in the party primary who is solidly positioned as the frontrunner. Mamdani, who has run on a agenda of economic justice and promised to halt rent increases for about two million city residents, has outpaced his rival by double-digits in every poll conducted in the fall, and it is very much the progressive's election to lose.

The Controversial Campaign

However, Cuomo, who resigned as governor in 2021 amid accusations of sexual harassment, has made it clear he will battle to the finish, and not necessarily in an above-the-belt fashion. He has trashed his opponent's objectives as unrealistic, and in recent days chuckled along as a radio host made anti-Muslim comments about the candidate, who is a Muslim. Recently, the independent was widely condemned as bigoted after posting an AI-generated ad that included a slew of racial caricatures and showed his opponent releasing a convicts.

This represents a particularly ugly conclusion to an election that could be critical to the path that the Democratic party, floundering in its reaction to the former president's authoritarian grabs, adopts in the near future.

National Implications

If Mamdani wins convincingly, the party establishment who have declined to support his bid will be forced to reckon with a platform that has resonated with Americans' anger at economic disparity, soaring price rises and the establishment. It would be difficult for the Senate leader and Hakeem Jeffries not to adopt at least some of Mamdani's ambitious ideas about affordability, given the newcomer has created an enthusiasm within the party arguably not seen since the Vermont senator ran for president in 2016.

However, if the former governor, who had been expected to win easily in the June primary, complete a remarkable comeback victory, it could cement national Democrats' existing approach of cautious, uninspiring resistance – a tactic that has infuriated grassroots members. A NYC rejection of the progressive's progressive, positive message could convince Schumer and Jeffries that the best plan is to stick to the political center – even as polls show the present version of the Democratic party is widely disliked across the country.

Campaign Energy

Residents of New York appear to favor the progressive agenda. Surveys show that Mamdani supporters are far more enthusiastic about their candidate than his opponent's supporters, something that has been apparent during the race. Mamdani's snappy videos on digital platforms, his hopeful outlook for New York and his readiness to actually venture out and connect with voters in the city has attracted an force of more than 50,000 supporters, many of them youth or first-time voters.

Negative Tactics

Yet, Cuomo, 67, isn't giving up. And with the risks stacked against him, the ex-leader has resorted to ugly messaging in the final days.

After spending months launching various attacks at Mamdani to see what might resonate, the independent has narrowed his focus on targeting the candidate personally. He has labelled Mamdani, who was of Ugandan origin to Indian parents, an "radical", and popped up on Fox Business for an interview with Maria Bartiromo, where Cuomo claimed the city “will not survive” Mamdani as city leader. It reached a nadir last week, when Cuomo chuckled and said “that’s another problem” after a broadcaster said the candidate would “cheer” another 9/11-style incident.

Political Landscape

This strategy mirrors 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 maybe that is expected. A group of wealthy residents, including some who contributed to the Republican in the 2024 election, have invested heavily into trying to get the independent into office, as other powerful voices have urged the Republican candidate to drop out from the contest.

Political Histories

For the Cuomo camp, and his wealthy backers, are concerned, it should never have come to this point. When Mamdani, one of one hundred fifty New York state assembly members, launched his mayoral bid in October 2024, few had known him, and in truth, barely anyone even noticed.

The former governor, by comparison, entered smoothly into the race in March 2025 and became the instant favorite. He was the big beast who seemingly held every edge. The classic establishment figure, he had wed a political dynasty member and served in a Democratic presidency. He assumed office as the state's leader in over a decade ago, 17 years after his parent, Mario Cuomo, left office from the identical role.

The progressive, who was voted in to the state legislature in 2020, does not have the same political heritage. But his dedication to providing no-cost transit and free childcare – along with the rent control promise – present a more positive vision of the future than his opponent's pessimistic predictions about “mayhem” and rising criminal activity, and his vow to hire more police officers.

Recent Challenges

Nevertheless, the candidate has encountered difficulties in the final phase, after video emerged suggesting him implying the NYPD and the IDF were intertwined.

“We have to make clear that when the pressure of the police is on your throat, it’s been laced by the Israeli military,” the candidate said in the clip, recorded at a Democratic Socialists of America gathering in recent years. The progressive, a longtime critic of the Israeli government who has said the country is committing genocide in Gaza, indicated he was criticizing cooperative programs between the city police and Israeli forces.

Powerful Moment

As the race closes, Mamdani seems to have gained sympathy and support, however, for his reaction to Cuomo’s escalating attacks.

The progressive addressed the independent's 9/11 remarks in an emotional video. In it, the candidate remembered how, when he first campaigned for state assembly, a family member advised to him that he did not have to tell people about his Muslim faith. It was a lesson, Mamdani 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 hidden spaces alone where followers of Islam could express their full identities, and that if we were to step out from those seclusion, then it is in those shadows that we must leave our faith.”

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