New York City faces a potential exodus of nearly 1 million residents if Zohran Mamdani secures victory in the upcoming mayoral race, according to recent polling data. The survey reveals that 25% of New Yorkers would consider leaving the city, while 9%—approximately 765,000 people—say they would “definitely” flee if Mamdani becomes mayor.

The projections highlight growing discontent with Mamdani’s leadership style, with respondents describing his vision for New York as a “disaster,” “hell,” and a “sh–hole.” Pollster James Johnson noted that older residents, Staten Islanders, and white voters are most likely to abandon the city, citing concerns over economic stability and governance. Men showed greater willingness to leave than women, with 12% of men and 7% of women expressing certainty about relocating.

Mamdani’s projected lead in recent polls, including a 40.6% favorability rating in an AtlasIntel survey, contrasts with shifting public sentiment. A J.L. Partners poll suggests his support could erode, particularly among high earners, with 7% of those making over $250,000 annually pledging to depart. The potential departure of 2.12 million residents—nearly a quarter of the city’s population—would have “seismic” economic consequences, according to analysts.

Despite these concerns, Mamdani has secured endorsements from prominent Democratic figures, including Governor Kathy Hochul and former President Barack Obama, who praised his campaign but stopped short of formal support. His recent rally with Alexandria Ocasio-Cortez and Bernie Sanders underscores his alignment with progressive policies.

With polls closing in 24 hours, the outcome remains uncertain. If Mamdani wins, New York City could face a historic mass migration, reshaping its demographic and economic landscape. The results will determine whether the city’s residents stay or flee amid escalating tensions over governance and direction.
