New Yorkers will discover the identity of their new city leader this election day, in a contest that will decide who runs and protects the nation's largest city at a time when Donald Trump 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 Democratic figures against each other. The contest has turned into an acrimonious face-off, laced with alleged racial bias and Islamophobia, but it is the political differences between the two leading candidates that could have significant consequences for how the party performs in next year's congressional races.

The Progressive Challenger

In the progressive corner is the democratic socialist, the young progressive candidate whose meteoric rise and grassroots campaign has attracted international attention. Representing the old guard is the former governor, the ex- Democratic New York governor now campaigning independently – and benefiting from the support of wealthy contributors and big business.

With days to go, it is Mamdani, the one-time underdog who beat Cuomo in the Democratic primary who is solidly positioned as the frontrunner. The candidate, who has campaigned on a agenda of affordability and promised to halt rent increases for about two million city residents, has outpaced Cuomo by double-digits across all surveys taken in the fall, and it is very much the progressive's race to throw away.

A Bitter Contest

However, Cuomo, who stepped down as governor in 2021 amid accusations of sexual harassment, has stated clearly he will battle to the finish, and not necessarily in an above-the-belt fashion. He has criticized his opponent's goals as unrealistic, and in recent days chuckled along as a broadcaster made Islamophobic remarks about the candidate, who is Muslim. Two weeks ago, Cuomo was strongly criticized as racist after sharing an AI-generated ad that included a series of racial caricatures and showed his opponent freeing a group of criminals.

It's been a rather grubby conclusion to an election that could be critical to the path that the Democratic party, struggling in its response to Trump's power moves, takes in the near future.

Broader Consequences

Should the progressive wins convincingly, the establishment party leaders who have refused to endorse his bid will be compelled to address a platform that has appealed to voters' frustration at inequality, inflation and the political elite. It would be hard for the Senate leader and the House leader not to embrace at least a portion of Mamdani's progressive proposals about economic justice, given the fresh face has created an enthusiasm within the party arguably not seen since Bernie Sanders ran for president eight years ago.

However, if Cuomo, who had been predicted to sail to victory in the Democratic primary, achieve a surprising comeback win, it could cement the party's existing approach of cautious, lackluster opposition – a tactic that has infuriated the party base. A New York defeat of the progressive's optimistic platform could convince party leaders that the wisest course is to stick to the center – even as polls show the current iteration of the Democratic party is deeply unpopular nationwide.

Campaign Energy

Residents of New York seem to prefer the Mamdani vision. Polls show that Mamdani supporters are far more enthusiastic about their choice than his opponent's supporters, something that has been evident during the race. The candidate's snappy videos on digital platforms, his optimistic vision for the city and his willingness to actually venture out and meet people in the city has drawn an force of more than 50,000 volunteers, many of them young or first-time voters.

Negative Tactics

Yet, Cuomo, in his late sixties, isn't giving up. And with the risks stacked 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 resonate, Cuomo has narrowed his focus on attacking Mamdani personally. He has labelled his rival, who was of Ugandan origin to South Asian heritage, an “extremist”, and popped up on Fox Business for an interview with Maria Bartiromo, where the candidate claimed the city “will not survive” his opponent as city leader. It reached a nadir last week, when the former governor laughed along and said “that’s another problem” after a broadcaster said the candidate would “cheer” another terrorist incident.

Political Landscape

The line of attack mirrors much of what Trump, who has sent the national guard to Washington DC and warned to do the same to New York, has said about the progressive, and maybe that shouldn’t come as a surprise. A group of billionaire New Yorkers, including some who donated to Trump in the 2024 election, have invested heavily into trying to elect the independent into office, as other influential figures have urged Curtis Sliwa to withdraw from the race.

Candidate Backgrounds

For the his team, and his wealthy backers, are concerned, it should not have reached to this point. When the assemblyman, one of one hundred fifty New York state assembly members, launched his mayoral bid in last year, few had known him, and in reality, few even noticed.

Cuomo, by comparison, entered smoothly into the contest in March 2025 and became the immediate frontrunner. He was the big beast who apparently held every edge. The quintessential political insider, he had married a Kennedy and worked in a Democratic presidency. He became the state's leader in 2011, 17 years after his father, the former governor, stepped down from the identical role.

The progressive, who was voted in to the state legislature in recently, does not have the same political heritage. But his dedication to providing free buses and free childcare – along with the freeze-the-rent pledge – offer a more positive vision of the future than Cuomo’s pessimistic predictions about “mayhem” and rising criminal activity, and his vow to hire more police officers.

Campaign Controversies

Nevertheless, the candidate has faced difficulties in the final phase, after video surfaced appearing to show him implying the NYPD and the IDF were intertwined.

“We have to make clear that when the pressure of the police is on your neck, it’s been influenced by the IDF,” Mamdani said in the clip, recorded at a DSA gathering in recent years. Mamdani, a vocal opponent of the Israeli government who has said the country is engaging in atrocities in Gaza, indicated he was criticizing joint training exercises between the NYPD and IDF.

Emotional Response

With the election nearing, the candidate seems to have gained empathy and backing, however, for his response to his opponent's escalating attacks.

Mamdani responded to the independent's terrorism comments in an emotional video. In it, the candidate recalled how, when he first ran for state assembly, a family member advised to him that he did not have to disclose about his Muslim faith. It was a lesson, Mamdani said, that many Muslim New Yorkers had been taught “again and again”: “That safety could only be found in the margins 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.”

Addressing the actions of his opponents, who has alleged Mamd
