Luke Bronin scored a decisive victory over longtime Rep. John Larson in Connecticut’s Democratic primary Tuesday, marking another defeat for AIPAC which had backed the 14-term congressman.

The pro-Israel lobby group is increasingly viewed as politically toxic in Democratic primaries across the country, with several progressive candidates notching victories after making opposition to the group a centerpiece of their campaigns.

Israel and the American Israel Public Affairs Committee, however,  were not at the forefront of the contest in Connecticut’s 1st Congressional District, reflecting a more nuanced picture regarding Democratic voters’ shifting sentiments toward Israel. 

Bronin and Larson, the race’s two candidates with more traditionally pro-Israel positions, together won nearly 90% of the vote, with Bronin receiving 53% while Larson received 34%. The two progressive candidates in the race, Jillian Gilchrest and Ruth Fortune, who both accused Israel of genocide in Gaza, finished a distant third and fourth.

Bronin, 46, who has Jewish ancestry on his father’s side, is the former mayor of Hartford and also served in the Obama Administration as the Deputy Assistant Secretary for Terrorist Financing and Financial Crimes. His campaign largely centered on affordability and emphasizing the need for new leadership in the Democratic party.

“If we are going to fix this mess that we are in, we need to build a Democratic Party that is bringing a whole new energy to this fight,” Bronin told supporters following his victory.

Israel was not entirely absent from the campaign. Larson, who first took office in 1999, split with Bronin during a primary debate last month when Larson defended his recent vote in support of U.S. military aid to Israel.

“Yes, I voted in favor of making sure that Israel, our ally, is going to get the aid from the United States that it needs. But the Palestinians need humanitarian aid, and Donald Trump has got to enforce the law,” Larson said.

Bronin pushed back at  Larson, replying, “Trusting Donald Trump to do the right thing is a mind-blowing example of putting hope over all of the evidence in front of us.”

While Larson had long supported Israel during his tenure in Congress, he has been critical of Israel’s prosecution of the war in Gaza and treatment of Palestinians and vocally opposed the United States’ war in Iran.

Bronin, meanwhile, has said he is against taxpayer money going toward funding offensive military aid to Israel, though he supports “defenses for civilians that protect civilian life against rockets and missiles and drones.”

“I think it’s hugely important that Israel exists as a safe, secure homeland for the Jewish people,” Bronin said when asked about his views on Israel on The Lisa Wexler Show in May. He also spoke out against Prime Minister Benjamin Netanyahu, explaining that the premier had  “done enormous damage to Israel’s security, Israel’s standing in the world,” adding that “we have an obligation as a country to say what’s happening is not okay.”

Bronin slightly outraised Larson on the campaign trail, receiving roughly $3.1 million largely from individual donations from billionaires and large firms, while Larson received $2.7 million and relied more on donations from PACs, according to the Federal Election Commission.

Larson received roughly $120,000 in AIPAC-linked donations during the campaign cycle, according to the campaign finance database Open Secrets.

Bronin will now face Republican Amy Chai, a physician and mental health advocate, in the general election for the state’s first congressional district. The district, which spans Bristol, Hartford and Torrington, is home to 27,800 Jews, representing 3.9% of the total population, according to the Berman Jewish Data Bank.
