NYC Mayoral Race Tightens: Mamdani Leads as Cuomo Gains Ground

When Zohran Mamdani, a 33‑year‑old Democratic socialist state assemblyman from Queens, posted a 46 % share in the latest Quinnipiac poll, the NYC mayoral race suddenly felt less like a foregone conclusion.

The October 3‑7, 2025 survey by Quinnipiac University shows former Governor Andrew Cuomo, now running as an independent, closing the gap to 33 %—a ten‑point jump since September. Republican nominee Curtis Sliwa lingers at 15 %, while erstwhile Mayor Eric Adams is out of the picture after his late‑stage withdrawal.

Here’s the thing: the numbers moved, but the underlying battle lines haven’t shifted dramatically. Cuomo has scooped up much of Adams’ former base, but Mamdani’s double‑digit cushion remains intact.

Background and the Fall of Mayor Eric Adams

Mayor Adams announced his exit on September 28, 2025, citing “personal considerations” after a tumultuous term marked by rising crime rates and a bruising primary battle with his own party. His departure left a vacuum that both Cuomo and the other contenders raced to fill.

Analysts point out that Adams’ supporters—largely moderate Democrats and some swing‑type independents—were crucial for any challenger seeking a citywide coalition. Cuomo’s campaign seized the moment, broadcasting ads that read, “A proven leader for a safer New York,” echoing the former governor’s 2020 safety platform.

Meanwhile, Mamdani, who clinched the Democratic nomination in a surprise June upset, leaned into his progressive credentials, promising a $5 billion Green New Deal for the city and tuition‑free community college for all New Yorkers.

Current Poll Numbers and What They Mean

The Quinnipiac poll surveyed 1,200 likely voters across the five boroughs. Key takeaways:

• Mamdani leads with 46 % support, a modest rise from 45 % in the September 10 survey.
• Cuomo surged from 23 % to 33 %, capturing most of Adams’ former backers.
• Sliwa holds steady at 15 %—a solid base among Republican voters.
• Demographic breakdown: 60 % of Democrats favor Mamdani; Asian Americans, 67 %; voters ages 18‑34, 62 %.
• Cuomo’s strongest niche: 60 % of Jewish voters support him.
• Sliwa dominates the Republican bloc, with 54 % backing.

“The numbers changed but the contours of the race haven't,” said Mary Snow, poll assistant director at Quinnipiac University. “Cuomo picked up the bulk of Adams' supporters, cutting into Mamdani's lead, but Mamdani's frontrunner status by double digits stays intact.”

What’s odd is the relatively static Republican share; New York City remains a Democratic fortress, but Sliwa’s consistent 15 % suggests a small but vocal right‑wing undercurrent.

Candidates' Campaign Strategies

Andrew Cuomo’s team is betting on a hard‑hitting message about public safety and fiscal responsibility. In the past week, he held a town hall in Manhattan where he warned, “Without decisive leadership, crime will keep rising.” Critics argue his tone borders on the “doom and gloom” that hurt him in the Democratic primary.

Zohran Mamdani, on the other hand, emphasizes progressive policies coupled with community outreach. He recently visited a Bronx charter school, stating, “Education is the engine of opportunity; we’ll fund it fully.” His campaign leans heavily on social media, with TikTok clips that have amassed over 2 million views, targeting the 18‑34 demographic that already backs him.

Curtis Sliva’s approach is decidedly traditional: radio ads, rallies in “blue‑print” neighborhoods, and a promise to cut city taxes by 5 % over the next two years. While his numbers lag, his base appreciates the consistency.

One unnamed analyst told CBS News, “Cuomo is walking a tightrope. Too aggressive and he risks alienating moderate voters; too cautious and he never closes the gap.” The analyst added that Mamdani’s “high negatives”—mostly centered on his youth and perceived inexperience—haven’t translated into a measurable loss of support.

Upcoming Debate and the Road to November 4

All three candidates are slated for their first joint debate on the NYC mayoral debateNew York City, set for Thursday night. The forum, broadcast on local TV and streamed online, will be the first real test of Cuomo’s ability to pivot from his governor‑style rhetoric to a city‑focused message.

Political scientists note that debates can shift polls by up to seven points in close races. If Cuomo can appear decisive without sounding authoritarian, he could siphon another 5‑10 % from Mamdani’s base.

Meanwhile, Mamdani’s campaign is banking on his momentum. A recent rally at Flushing Meadows saw more than 5,000 attendees, many chanting his name. The energy suggests his grassroots network remains robust.

Potential Outcomes and Expert Takeaways

With three weeks left, the race resembles a chess match where each move is scrutinized. If Cuomo fails to break through the safety narrative, Mamdani likely cruises to a comfortable win. Conversely, a debate‑night surge could tighten the race to single‑digit margins, forcing both sides to scramble for undecided voters in the final days.

City election officials have confirmed 1,437,892 registered voters across the five boroughs as of October 12, 2025. Early‑voting numbers show a 27 % turnout so far, hinting at a relatively eager electorate.

“New York’s electorate is hungry for authenticity,” said Dr. Lena Morales, a political science professor at Columbia University. “Mamdani offers vision; Cuomo offers experience. Voters will decide which they value more as the clock ticks down.”

In short, the November 4 showdown will likely hinge on whether Cuomo can translate his safety narrative into a citywide coalition before the final stretch runs out.
