The three profound Jewish lessons of Mamdani’s astonishing victory
Takeaways for the incoming mayor’s opponents — and the mayor himself

Among pollsters familiar with the American Jewish vote, the events of Nov. 4, 2025 in New York City will go down as Opposite Day.
A CNN exit poll showed that Zohran Mamdani, the new mayor-elect, received just about 30% of the Jewish vote, while his opponents, former Gov. Andrew Cuomo and Curtis Sliwa, together received a total of 70%. Those numbers are effectively the inverse of the Jewish vote in decades of national elections, which have usually seen the Democratic candidate getting between 70% and 80% of the Jewish vote.
Now, that stark divide is one that Jews, and Mamdani, will have to learn to live with.
For the majority of Jews who opposed Mamdani, there are a few primary lessons.
First and foremost: If you want people to care about your most important issues, you first have to address their most important issues.
Pro-Palestinian positions may have fueled Mamdani’s politics and established his early volunteer base, but they didn’t win him the election. The New Yorkers who voted for him “overwhelmingly” said cost of living is their top issue, reported CNN.
For most New Yorkers who hit the polls, questions about Mamdani’s attitude toward Israel Israel — and even concerns about antisemitism — paled in importance beside affordability.
Yet one tone-deaf Jewish leader after another pleaded with voters to reject Mamdani because of his highly critical attitude toward Israel. That stance, they said, could lead to attacks on Jewish New Yorkers.
Exactly why should economically besieged New Yorkers care?
Second, I suspect we will find out that a good portion of the Jewish voters who did opt for Mamdani did so not despite his stance on Israel, but because of it.
Most American Jews say Israel has committed war crimes against Palestinians. Some 68% are unhappy with Prime Minister Benjamin Netanyahu. Most can’t vote against Netanyahu, but they can vote for Mamdani, or their local equivalent.
The Jewish vote for Mamdani was a rebuke to the mainstream Jewish leadership that organized against the mayor-elect. That leadership didn’t speak for these Jews. Mamdani did.
It’s also surely true that some portion of Jewish Mamdani supporters voted for him while opposing his views and statements about Israel — what my fellow Forward columnist Jay Michaelson called the “No-Yes option”. These Jewish voters saw Mamdani, in the last months of his campaign, reach out to Jewish leaders, political opponents, business interests and others as a sign that he was open to compromise and bridge-building.
And third: While many in the Jewish community had good reasons to oppose Mamdani, they should be grateful for those Jews who supported him. There is a certain blessing in the fact that center-left Jewish leaders like outgoing Comptroller Brad Lander and former New York City mayoral candidate Ruth Messinger got behind Mamdani — because under his administration they will now be in or near the room where it happens.
These leaders, who have been slammed by some as traitors, sell-outs and self-haters for supporting Mamdani, now have the opportunity to help him make good on his promise to protect and serve Jewish New Yorkers.
Mamdani built reassurance on that front into his victory speech Tuesday night.
“We will build a city hall that stands steadfast alongside Jewish New Yorkers and does not waver in the fight against the scourge of antisemitism,” he said, before pivoting to decry the Islamophobia he faced in the campaign.
But Mamdani himself has much to learn, too.
Tomorrow, when the party is over and the 34-year-old mayor-elect begins meeting with his transition team,what lessons should he draw from the Jewish vote’s split?
Above all, that “being overly controversial on Israel is not in his self-interest,” said Peter Dreier, a professor of politics at Occidental College in Pasadena, Calif. “He needs to bring people together. He needs to focus laser-like on running the city and his affordability agenda.”
It’s one thing to be critical of Netanyahu, and another to say, as Mamdani has, that he would boycott the joint research center between Cornell University and Israel’s Technion based on New York City’s Roosevelt Island. He should stick to the former.
And as he works to fulfill his promise to make New York more affordable, Mamdani must also keep his promise to Jewish New Yorkers to keep them safe.
There will be special, if unfair, scrutiny of how this Muslim mayor relates to his Jewish citizens, and Mamdani could prove the fearmongers to be, well, fearmongering.
He must show he can rein things in, said Dreier, who served as deputy mayor of Boston in the 1980s under Ray Flynn. Flynn was feared by the business elite but left office with a 74% approval rating. “We ran a very progressive campaign,” Dreier said, “and then we had to figure out what we were going to give in, and where we could hold the line.”
And it’s not just New Yorkers and New York Jews who will be watching. Mamdani’s religion and views on Israel have made it inevitable that American Jews across the country will be either on board, or on edge.
Will Mamdani work to flip the Jewish voter exit poll numbers for his next race back to the familiar 70/30? That would seem to be the move for a young politician with a promising career ahead of him, and with a Jewish constituency that is predisposed to vote for the Democrat.
But say he leans into his radical roots and betrays his promises? That would leave a lot of Jews feeling politically homeless — at a time when the Republicans are opening the doors to explicitly antisemitic far-right figures like Nick Fuentes and Candace Owens. The question of whether Jews still fit, politically, in the United States — and if so, where — is one that Mamdani will have a crucial role in answering.
“My rabbi has been on the job for three months and just gave a sermon about Mamdani,” Dreier said. “I mean, why the hell would a rabbi here in Pasadena care about who’s the mayor of New York?”
