Zohra Mamdani’s New York Victory Exposes Deepening Rifts in Jewish Democratic Politics

Zohra Mamdani’s victory as New York’s next mayor has exposed widening divisions within Jewish Democratic politics — a rift between traditional Jewish voters and younger progressives that could redefine political alignments in the years to come.

The 34-year-old Democratic Socialist defeated former Democratic Governor Andrew Cuomo, who ran as an independent, while dismissing allegations of antisemitism over her support for Palestinians in the Gaza conflict.

A Muslim immigrant, Mamdani capitalized on frustration among some Democrats and Jewish Americans over Israel’s conduct in Gaza. Many who had initially supported Israel’s actions became increasingly disillusioned — a shift that first emerged during last spring’s protests at Columbia University, which Mamdani openly backed and which boosted her political momentum.

According to a Pew Research Center survey last year, only half of Jewish Americans under 35 said Israel’s handling of the war was acceptable, compared to 68% of those aged 50 and above.

In Tuesday’s election, roughly one-third of Jewish voters supported Mamdani, exit polls showed — a striking result that helped secure her victory and unsettled many of her Jewish critics unaccustomed to losing their favored candidate.

“On the morning after the election, many in our community woke up with a sense of unease,” said Hindi Popko, senior vice president at UJA-Federation of New York. “There’s deep uncertainty about how Mayor Mamdani will lead once she takes office.”

Mamdani’s leadership was tested within hours of her win when antisemitic graffiti appeared at a Jewish day school in Brooklyn. She swiftly condemned the act, writing on X: “As mayor, I will always stand firmly with my Jewish neighbors to root out antisemitism from our city.”

A Divisive Slogan and Political Balancing Act

Critics have voiced concern over Mamdani’s past refusal to denounce the phrase “Globalize the Intifada” — a pro-Palestinian slogan some view as a call for violence against Jews. According to a July New York Times report, after her nomination, Mamdani privately assured business leaders she would avoid using the phrase and discourage others from doing so.

She has expressed support for the Boycott, Divestment, and Sanctions (BDS) movement, which calls for economic and cultural boycotts of Israel.

The Anti-Defamation League (ADL) recently launched a “Mamdani Monitor” to track her policy decisions and appointments, alongside a hotline for reporting antisemitic incidents. “Our mission is simple — to protect the Jewish people,” said ADL CEO Jonathan Greenblatt.

Republicans Seize the Moment

The growing split among Democrats over Israel has opened an opportunity for Republicans. Former President Donald Trump — a staunch supporter of Israeli Prime Minister Benjamin Netanyahu — urged Jewish voters to reconsider their allegiance, saying anyone backing Mamdani was a “fool.”

This came despite exit polls showing Democrat Kamala Harris won 79% of the white Jewish vote in the 2024 election.

Republican strategists hope to leverage Mamdani’s victory in next year’s midterms, particularly in competitive districts like that of GOP Congressman Mike Lawler north of New York City. “Mamdani’s arrival at Gracie Mansion could reshape Republican strategy and strengthen our grip on the House,” said GOP strategist Ford O’Connell.

Mamdani is also expected to play a pivotal role in next year’s gubernatorial race. Republican Congresswoman Elise Stefanik, a close Trump ally, has already announced her intention to seek her party’s nomination and criticized Democratic Governor Kathy Hochul for backing Mamdani.

A Fragmented Electorate

Mamdani’s campaign centered on New York’s high cost of living and economic inequality — themes that resonated strongly with younger, progressive voters. Even some of her critics, including Greenblatt, acknowledged that her focus on affordability helped fuel her rise.

Her Jewish supporters argue that the election underscores the diversity of Jewish political identity.

“I support Mamdani not despite her views on Israel and Palestine, but because of them,” said Roni Zahavi-Bruner, a 26-year-old Israeli who campaigned for her. “Speaking out against genocide shouldn’t be controversial.”

Others, however, backed Cuomo for his staunch support of Israel.

“I feel very uneasy,” said Allison Devlin, 50, a Jewish resident of Manhattan’s Upper East Side who voted for Cuomo. “I’m openly Jewish, openly Zionist — and I’m not sure what’s going to happen next or even if I’ll stay in the city.”

Corinne Greenblatt, a 27-year-old working in higher education, said she appreciates Mamdani’s efforts to engage a broader spectrum of the Jewish community. “Jewish politics are incredibly diverse,” she said. “This election made it clear that some Jews support Palestine, some support Israel, and others feel disconnected from either.”

Rabbi Andrew Kahn of Brooklyn noted that Mamdani has consistently reiterated her commitment to combating antisemitism, while criticizing groups like the ADL for “using Jewish fear as a pretext for surveillance and division.”

“Let’s give her the chance to prove her commitment to fighting antisemitism,” Kahn said, “and work together to build intercommunal solidarity that keeps all New Yorkers safe.”
