New York City Democratic Mayor Zohran Mamdani is more popular than ever about a month after his inauguration, according to a new poll from the Siena Research Institute.

The statewide finding marks a new peak for Mamdani’s standing since he emerged as a leading figure in city politics, offering an early glimpse of how New Yorkers beyond the five boroughs are assessing his work as mayor.

Why It Matters

The trend also followed a series of 2025 polls that showed Mamdani leading the New York City mayoral race and consolidating support among younger voters, setting the stage for his subsequent general election victory and early term agenda on affordability.

What To Know

According to the poll, Mamdani's favorability rating is 48 percent versus a 32 percent unfavorable rating. Mamdani's favorability rating in December was 46 percent versus a 31 percent unfavorable rating.

The Siena survey was conducted from January 26 to January 28 among 802 registered voters, with an overall margin of error of plus or minus 4.3 percentage points.

"The 48% favorable is the highest it’s ever been for Mamdani. He is viewed favorably by 64% of Democrats, unfavorably by 68% of Republicans, and favorably, 43-31%, by independents," the poll notes in part.

Earlier polling during the 2025 campaign routinely showed Mamdani leading a four-way field. In a New York Times/Siena survey, Mamdani had 46 percent, with strong support on affordability and housing, and a narrower edge in a hypothetical head-to-head with former Governor Andrew Cuomo.

What People Are Saying

Robert Y. Shapiro, political science professor at Columbia University, to Newsweek via email Tuesday: "This could be at least a brief 'honeymoon' effect for a newly elected mayor. He has not done anything disruptive so far, has worked with Governor [Kathy] Hochul on free child care possibilities, and he has done ok in handling the snow storm and current cold weather. The crime issue has not posed a problem and things seem relatively good on that front.

"By contrast with the disruption caused by ICE and the Trump administration, he has also looked comparatively good. So, we can say 'so far so good.' But this can change quickly as we know well."

What Happens Next

Future polling will test whether Mamdani can sustain or grow his standing as policies roll out and as statewide attitudes continue to shift on cost-of-living, public safety and state-city relations spotlighted throughout the 2025 campaign.
