A fresh Siena College survey has delivered sobering news for Democratic mayoral contender Zohran Mamdani: New York City’s Jewish voters overwhelmingly disapprove of him. Three out of four view the Queens Democrat unfavorably, with only 15 percent offering a positive rating—numbers that stand in stark contrast to the more mixed opinion of the general electorate.

The rift stems largely from Mamdani’s record of sharp anti-Israel statements. He has labeled Israel an “apartheid” state, called for halting U.S. arms sales to Jerusalem, and refused to acknowledge Israel’s right to exist as a Jewish state. His embrace of the boycott, divestment, and sanctions movement and defense of slogans tied to past waves of anti-Jewish violence have drawn fierce criticism from community leaders. The U.S. Holocaust Memorial Museum rebuked him after he likened “globalize the intifada” to the Warsaw Ghetto Uprising.

This sentiment is translating directly into the race: just 20 percent of Jewish voters say they plan to back Mamdani. The poll shows many are gravitating toward Andrew Cuomo or Curtis Sliwa instead, suggesting that alienating the Jewish electorate could have serious electoral consequences in a city where their votes can prove decisive. Now what are going to do about that 20 percent?
