New Yorkers will learn who will be their next mayor this election day, in a contest that will determine who runs and defends the nation's most populous metropolis at a time when the former president has vowed to send military troops to the city.

Against that backdrop, New York has witnessed a race for mayor that has matched two very different Democrats against one another. The contest has turned into an acrimonious showdown, laced with accusations of racial bias and Islamophobia, but it is the ideological divide between the two main candidates that could have major implications for how the Democratic party performs in next year's midterm elections.

The Progressive Challenger

On the left side is the democratic socialist, the young progressive candidate whose rapid ascent and grassroots campaign has attracted international attention. On the establishment side is Andrew Cuomo, the ex- New York governor now campaigning independently – and benefiting from the backing of wealthy contributors and corporations.

With days to go, it is the progressive, the one-time underdog who beat his opponent in the Democratic primary who is solidly positioned as the leading candidate. The candidate, who has run on a platform of economic justice and promised to freeze rent for about two million city residents, has outpaced Cuomo by significant margins in every poll taken in the fall, and it is very much the progressive's election to throw away.

A Bitter Contest

However, the former governor, who resigned as governor in recent years amid allegations of sexual harassment, has stated clearly he will fight to the finish, and not necessarily in an fair manner. He has criticized Mamdani's objectives as unrealistic, and in recent days chuckled along as a broadcaster made Islamophobic remarks about Mamdani, who is Muslim. Two weeks ago, Cuomo was widely condemned as bigoted after posting an AI-generated ad that featured a series of racist stereotypes and showed Mamdani releasing a convicts.

This represents a particularly ugly end to an race that could be key to the direction that the party, struggling in its reaction to Trump's authoritarian grabs, takes in the coming years.

National Implications

If the progressive wins convincingly, the party establishment who have refused to endorse his campaign will be forced to reckon with a message that has appealed to voters' frustration at inequality, inflation and the establishment. It would be hard for Chuck Schumer and the House leader not to embrace at least a portion of Mamdani's progressive proposals about economic justice, given the newcomer has generated an excitement within the Democratic ranks arguably not witnessed since Bernie Sanders campaigned for the White House eight years ago.

Conversely, if the former governor, who had been predicted to win easily in the June primary, complete a remarkable comeback victory, it could cement national Democrats' existing approach of cautious, uninspiring opposition – a tactic that has infuriated the party base. A New York rejection of Mamdani's progressive, positive message could convince Schumer and Jeffries that the best plan is to stick to the political center – even as surveys show the present version of the party is widely disliked nationwide.

Voter Enthusiasm

Residents of New York appear to favor the progressive agenda. Surveys show that his backers 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 social media, his optimistic vision for New York and his willingness to actually get out and connect with voters in the city has attracted an army of over fifty thousand supporters, many of them youth or new participants.

Negative Tactics

However, the former governor, in his late sixties, continues to fight. And with the risks stacked against him, the former governor has resorted to ugly messaging in recent weeks.

After spending months throwing basically everything at his opponent to see what might stick, Cuomo has narrowed his focus on attacking the candidate personally. He has called his rival, who was of Ugandan origin to South Asian heritage, an “extremist”, and popped up on conservative media for an interview with a rightwing host, where Cuomo asserted New York “will not survive” Mamdani as city leader. It reached a nadir recently, when the former governor laughed along and said “that’s another problem” after a radio host said the candidate would “cheer” another terrorist incident.

Campaign Dynamics

This strategy mirrors much of what Trump, who has sent the national guard to Washington DC and threatened to do the same to NYC, has said about the progressive, and perhaps that is expected. A group of billionaire New Yorkers, including some who donated to Trump in the last presidential race, have invested heavily into trying to get Cuomo elected, as other powerful voices have urged Curtis Sliwa to withdraw from the race.

Political Histories

For the Cuomo camp, and his wealthy backers, are worried, it should not have reached to this point. When Mamdani, one of one hundred fifty state legislators, launched his mayoral bid in last year, few had known him, and in truth, barely anyone even noticed.

Cuomo, by comparison, eased his way into the race in March 2025 and became the immediate frontrunner. He was the big beast who apparently held all the advantages. The quintessential political insider, he had married a political dynasty member and worked in Bill Clinton’s administration. He assumed office as New York governor in 2011, seventeen years after his father, the former governor, stepped down from the same position.

Mamdani, who was voted in to the state legislature in 2020, does not have the comparable background. 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 unfettered crime, and his promise to increase police presence.

Recent Challenges

Nevertheless, the candidate has encountered difficulties in recent days, after video surfaced appearing to show him suggesting the New York police department and the Israel Defense Forces were connected.

“We have to make clear that when the pressure of the NYPD is on your neck, it’s been influenced by the IDF,” Mamdani said in the recording, filmed at a DSA gathering 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 NYPD and Israeli forces.

Emotional Response

As the race closes, the candidate appears to have won sympathy and support, however, for his reaction to Cuomo’s increasing rhetoric.

The progressive addressed the independent's terrorism comments in an emotional video. In it, Mamdani recalled how, when he first ran for state assembly, a family member advised to him that he did not have to tell people about his religion. It was a realization, he said, that many Muslim New Yorkers had been taught “again and again”: “That security could only be found in the margins of our community. That it is in those hidden spaces alone where Muslims could embrace their full identities, and that if we were to step out from those seclusion, then it is in those silence that we must set aside our faith.”

Speaking to the actions of Cuomo and Sliwa, who has alleged Mamd
