Majority of New York Jewish voters view Mamdani unfavorably - poll

According to a Siena poll conducted in September, 64% of Jewish voters in New York state hold an unfavorable view of Mamdani, compared with just 33% who view him favorably.

New polling data presented by CNN on Wednesday revealed a significant divide between New York City Mayor Zohran Mamdani and Jewish voters in New York state, pointing to a sharp erosion of traditional support for the Democratic Party among this group.

According to a September Siena poll, 64% of Jewish voters in New York state view Mamdani unfavorably, compared with 33% who view him favorably.

The disparity is particularly striking when compared with the broader electorate. Statewide, Mamdani, a democratic socialist elected mayor in November 2025, holds a 46% favorable rating, compared with 44% who view him unfavorably. Among Jewish voters, however, the figures tell a markedly different story.

CNN analysis reveals 31-point favorability gap among Jewish voters

In an analysis presented on Wednesday, CNN senior data analyst Harry Enten reported that Mamdani had a net favorability rating of minus 23 percentage points among Jewish voters, compared with a positive eight-point rating among voters statewide.

The figures represent a 31-point gap between Jewish voters' attitudes toward the mayor and those of the general electorate.

Enten linked the findings to Mamdani's positions on Israel and Prime Minister Benjamin Netanyahu, which he said do not align with the views of many Jewish voters in New York.
