Mayor Zohran Mamdani’s socialist cronies who swept last week’s Democratic primaries boasted about an affordability message — but critics say it was anti-Israel furor that is fueling the party’s swing to the left.

State Democratic Party chairman Jay Jacobs admitted voters’ feelings on Israel helped propel Mamdani buddies to three House primary victories, including firebrand Darializa Avila Chevalier and former city Comptroller Brad Lander, who upset incumbent Reps. Adriano Espaillat and Dan Goldman, respectively.

Both Espaillat and Goldman backed the Jewish state — which may have motivated young activist liberals with pro-Palestinian views who have staunchly opposed Israeli military action in Gaza.

“Yes. I do think the Israel-Palestinian issue had an impact in the election,” Jacobs told The Post on Sunday. “It hurt establishment Democrats.

“There are people who may have voted against Espaillat and Goldman because of it,” he added. “It was important to the activists who came out and voted.”

State Democratic Party chief Jay Jacobs on Sunday said he opposes Mayor Zohran Mamdani repealing executive orders targeting antisemitism and supporting Israel but added he still wants to be “fair-minded.”

The pro-Palestinian, anti-Israel campaign was a “more important issue for those who came out and voted” in low-turnout primary elections that saw only about 17% of party voters citywide participate, Jacobs said.

The national civil rights group the Anti-Defamation League blasted the insurgency for riding a wave of antisemitic sentiment to wins in the Big Apple, the city with the largest Jewish population outside Israel.

“On Tuesday night in New York City, a movement built on antisemitic rhetoric won three congressional primaries,” the ADL said in a statement on X.

The statement noted that as Mamdani moved through the jubilant crowd at a DSA victory party on the night of the primaries, attendees chanted, “From the river to the sea,” a phrase viewed as a call to wipe out Israel.

“We’re witnessing candidates succeed not in spite of their demonizing rhetoric against the Jewish community and the Jewish state, but because of it,” the ADL said.

“When leaders cheer slogans that dehumanize Jews, it does not stay at a victory party. It bleeds into schools, neighborhoods and daily life, putting Jewish families, children and communities at risk.”

The Mamdani-backed House candidates were part of a push to the left of the party that came alongside wins by legislature candidates handpicked by the Democratic Socialists of America.

The results were compared to Rep. Alexandria Ocasio-Cortez’s victory in the 2018 elections and insiders and experts already say they could shift power in the state Democratic Party and reshape policy priorities for years to come.

Chevalier came under intense scrutiny during the campaign but still defeated five-term incumbent Espaillat in a close contest in the 13th House District, which covers Harlem/Washington Heights and parts of the Bronx.

She had attended an anti-Israeli rally in Times Square one day after Hamas’ horrific terrorist attacks on Israel on Oct. 7, 2023. At the rally, demonstrators torched the Israeli flag and flashed swastikas.

Chevalier centered her platform on halting US military aid to Israel and pushing for full divestment from the Jewish state.

DSA candidate Claire Valdez, who is now a state Assembly member, won an open seat in Brooklyn-Queens House District 7 by defeating Brooklyn Borough President Antonio Reynoso, the favored candidate of retiring Rep. Nydia Velazquez.

Meanwhile, Lander — who is Jewish and a former DSA member, claimed Israel is committing genocide in Gaza, He easily defeated two-term incumbent Goldman in a landslide.
