Mamdani's New York victory exposes fault lines in Jewish Democratic politics

NEW YORK (Reuters) - Zohran Mamdani’s election as New York’s next mayor exposed a deepening rift between traditional Democratic Jewish voters and younger progressives — one that could reshape politics for years in the metropolitan area with the world’s largest Jewish population outside Israel.

Mamdani, a 34-year-old democratic socialist, handily defeated Andrew Cuomo, the Democratic former governor of New York who ran as an independent, while beating back accusations of antisemitism over his support of Palestinians in the conflict in Gaza.

A Muslim immigrant, Mamdani benefited from a wave of anger over Israel’s conduct in Gaza among some Democrats and Jewish Americans who had initially supported it but grew disillusioned.

That shift manifested itself in spring protests at Columbia University last year that Mamdani supported and politically benefited from.

A Pew Research Center poll last year found that just half of Jewish Americans under 35 said the way Israel has carried out the war has been acceptable, while 68% of Jews ages 50 and older said it was acceptable.

In New York, about one-third of Jewish voters in Tuesday's election supported Mamdani, exit polls showed, powering a victory that alarmed his Jewish opponents unaccustomed to backing the losing candidate.

“The morning after the election, many members of our community woke up with a sense of unease,” said Hindy Poupko, a senior vice president at the UJA-Federation of New York, a major Jewish nonprofit. “There's a lot of uncertainty about how Mayor Mamdani might act once in City Hall.”

Mamdani was tested quickly. When in the hours after his election antisemitic graffiti was scrawled on a Brooklyn Jewish Day School, the mayor-elect condemned the act.

“As Mayor, I will always stand steadfast with our Jewish neighbors to root the scourge of antisemitism out of our city,” he posted on X.

'GLOBALIZE THE INTIFADA'

Jewish opponents of Mamdani expressed concern about his refusal to condemn the phrase "globalize the intifada," a slogan of support for Palestinians that some interpret as a call to violence against Jewish people. After his nomination, Mamdani privately told a group of business leaders that he would not use the phrase and would discourage others from using it, according to a July New York Times report.

He has said he supports the Boycott, Divestment, Sanctions, or BDS, movement, which calls for the economic and cultural boycott of Israel.

The Anti-Defamation League last week launched a “Mamdani Monitor” to track his executive appointments and other actions for potential harm to the Jewish community. It also established a tip line for New York residents to report incidents of antisemitism.

“Our job is quite simple - to protect the Jewish people,” said Jonathan Greenblatt, the group's chief executive.

COURTING VOTERS

Amidst the Democratic divisions over Israel's conduct in Gaza, Republican President Donald Trump, an ardent backer of Israeli Prime Minister Benjamin Netanyahu, has made the case to Jewish voters that his party is a better home.

That appeal came despite the fact that Trump's 2024 rival, Democrat Kamala Harris, won 79% of the white, Jewish vote in 2024, according to exit polls.

Trump said on Tuesday any Jewish voter who supported Mamdani was a "stupid person.”

The Republican Party was rocked by accusations of antisemitism after right-wing pundit Tucker Carlson hosted white nationalist Nick Fuentes last month for a sympathetic interview on his podcast.

Carlson, a former Fox News Channel personality, was denounced by Republican lawmakers including U.S. Senator Ted Cruz of Texas, who this week said, “a handful of voices are spreading this garbage, and it is giving every one of us a time for choosing.”

Republicans plan to seize on Mamdani’s election to court more Jewish support in next year’s midterms, when control of Congress is at stake. That backing could prove pivotal in swing districts like the one north of New York City held by Republican Mike Lawler.

“Mamdani’s ascent to Gracie Mansion could rewrite the playbook for Republicans, tightening their hold on the U.S. House,” said Ford O’Connell, a Republican strategist, referring to the New York mayor's official residence.

Mamdani also promises to be a factor in next year's race for New York governor. Elise Stefanik, a top Trump ally, said last week she will seek the Republican nomination and assailed Democratic Governor Kathy Hochul for endorsing Mamdani.
