New York, NY – A new HarrisX poll finds the 2025 New York City mayoral general election shaping up as a close contest, with Assemblymember Zohran Mamdani running neck-and-neck with former Governor Andrew Cuomo and Republican Curtis Sliwa in a four-way race — while outperforming Mayor Eric Adams in head-to-head matchups.
In the survey of 585 registered NYC voters conducted July 7–8, Mamdani led with 26%, followed by Cuomo at 23% and Sliwa at 22%, all within the margin of error. Adams trailed with 13%, and 15% of voters remained undecided.
Without Adams in the race, Cuomo (31%) and Mamdani (29%) were statistically tied with Sliwa (28%). Without Cuomo, Mamdani widened his lead to 35%, 10 points ahead of Sliwa, with Adams at 19%.
In direct matchups, Mamdani beat Adams 43% to 36%, but trailed Cuomo 50% to 35%, giving Cuomo a decisive 15-point advantage in that scenario.
Pollster Dritan Nesho said the results reflect a volatile race, with Mamdani benefiting most if Cuomo does not run, while Cuomo’s high name recognition and moderate appeal make him a strong challenger in the general election.
