Residents of the Big Apple will discover the identity of their next mayor this Tuesday, in a contest that will determine who runs and protects the nation's largest city at a moment when the former president has vowed to send military troops to the city.

Against that backdrop, New York has experienced a mayoral election that has pitted two very different Democrats against each other. The contest has turned into an acrimonious showdown, marked by alleged racial bias and Islamophobia, but it is the ideological divide 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 progressive candidate whose rapid ascent and grassroots campaign has brought international attention. On the establishment side is the former governor, the former New York governor now campaigning independently – and enjoying the backing of ultra-rich donors and big business.

With days to go, it is the progressive, the former longshot who beat his opponent in the Democratic primary who is solidly positioned as the frontrunner. Mamdani, who has run on a platform of economic justice and pledged to halt rent increases for about two million city residents, has led his rival by double-digits across all surveys taken 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 recent years amid allegations of sexual harassment, has made it clear he will battle to the finish, and not necessarily in an fair manner. He has trashed his opponent's goals as unachievable, and in recent days chuckled along as a broadcaster made anti-Muslim comments about Mamdani, who is a Muslim. Recently, the independent was widely condemned as racist after posting an AI-generated ad that featured a series of racist stereotypes and showed Mamdani releasing a group of criminals.

It's been a particularly ugly conclusion to an race that could be critical to the path that the party, struggling in its response to Trump's power moves, takes in the coming years.

Broader Consequences

Should the progressive wins convincingly, the party establishment who have declined to support his campaign will be forced to reckon with a platform that has appealed to voters' frustration at economic disparity, soaring price rises and the political elite. It would be hard for the Senate leader and Hakeem Jeffries not to adopt at least a portion of Mamdani's ambitious ideas about economic justice, given the fresh face has generated an enthusiasm within the party arguably not witnessed since the Vermont senator ran for president in 2016.

However, if the former governor, who had been predicted to win easily in the Democratic primary, complete a surprising comeback victory, it could reinforce national Democrats' current model of considered, lackluster resistance – a strategy that has infuriated grassroots members. A NYC rejection of Mamdani's progressive, positive message could convince Schumer and Jeffries that the wisest course is to remain in the center – even as surveys show the present version of the party is widely disliked nationwide.

Voter Enthusiasm

Residents of the city 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 evident throughout the campaign. The candidate's snappy videos on digital platforms, his hopeful outlook for the city and his readiness to actually get out and meet people in the metropolis has drawn an army of over fifty thousand supporters, many of them youth or new participants.

Negative Tactics

Yet, Cuomo, in his late sixties, isn't giving up. And with the risks against him, the ex-leader has resorted to negative campaigning in recent weeks.

After spending months launching various attacks at Mamdani to see what might stick, the independent has concentrated on targeting the candidate directly. He has labelled his rival, who was of Ugandan origin to Indian parents, an “extremist”, and appeared on Fox Business for an discussion with Maria Bartiromo, where the candidate claimed the city “will not survive” his opponent as city leader. It hit bottom recently, when the former governor chuckled and said “that’s another problem” after a broadcaster said the candidate would “cheer” another 9/11-style attack.

Campaign Dynamics

The line of attack mirrors much of what the former president, who has sent the military reserves to the capital and warned to do the same to New York, has said about the progressive, and maybe that shouldn’t come as a surprise. A set of wealthy residents, including some who donated to Trump in the 2024 election, have pumped millions into trying to get the independent into office, as other powerful voices have urged Curtis Sliwa to drop out from the contest.

Political Histories

As far as the his team, and his wealthy backers, are concerned, it should not have reached to this. When the assemblyman, one of 150 state legislators, launched his mayoral bid in last year, not many had heard of him, and in reality, few even noticed.

Cuomo, by comparison, entered smoothly into the contest in March 2025 and became the instant favorite. He was the political heavyweight who seemingly held every edge. The classic political insider, he had wed a political dynasty member and worked in Bill Clinton’s administration. He assumed office as the state's leader in over a decade ago, 17 years after his parent, the former governor, left office from the same position.

Mamdani, who was elected to the state legislature in recently, does not have the comparable background. But his commitment to providing no-cost transit and free childcare – along with the freeze-the-rent pledge – present 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

Still, the candidate has encountered difficulties in the final phase, after video emerged suggesting him suggesting the NYPD and the IDF were connected.

“We have to make clear that when the pressure of the police is on your neck, it’s been influenced by the Israeli military,” Mamdani said in the recording, recorded at a DSA gathering in recent years. The progressive, a vocal opponent of Israel who has said the country is engaging in atrocities in the Palestinian territory, suggested he was questioning cooperative programs between the NYPD and Israeli forces.

Powerful Moment

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

Mamdani responded to the independent's 9/11 remarks in an emotional video. In it, Mamdani recalled how, when he first ran for the legislature, a family member advised to him that he did not have to tell people about his Muslim faith. It was a realization, he said, that many local Muslims had been told “again and again”: “That security could only be found in the margins of our community. That it is in those hidden spaces alone where followers of Islam could express their full identities, and that if we were to emerge from those seclusion, then it is in those shadows that we must set aside our beliefs.”

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