A large majority of New York City Jews voted for Andrew Cuomo for mayor, with 63% of the Jewish population voting for him and 33% for Zohran Mamdani, a Wednesday CNN poll found following Mamdani's mayoral victory. 

Republican candidate Curtis Sliwa received support from 3% of the Jewish population.

Mamdani became the first Muslim to be elected as the city's mayor on Tuesday night. According to the poll, however, he did so by capitalizing on support from voters with no religious affiliation, while falling short of a majority among the city's three largest religious groups.

Jewish voters comprised 15% of the religious voter blocs

The election results highlight a contrast in priorities among New York’s diverse religious blocs. Overall, Catholic voters accounted for the largest share of the electorate at 27%, followed by those with no religious affiliation (24%), and Protestant/other Christian voters (21%). Jewish voters comprised 15% of the total.
