Luke Bronin, former mayor of Hartford, decisively defeated 14-term incumbent John Larson in Connecticut's 1st Congressional District Democratic primary on Tuesday, August 11, 2026. Bronin received 53% of the vote to Larson's 34%, with progressive candidates Jillian Gilchrest and Ruth Fortune finishing a distant third and fourth. The race was notable for the absence of Israel as a decisive factor, despite AIPAC's backing of Larson. Bronin, 46, who has Jewish ancestry, campaigned on affordability and new leadership. He outraised Larson, collecting roughly $3.1 million largely from individual donations from billionaires and large firms, while Larson raised $2.7 million with more PAC support. Larson received about $120,000 in AIPAC-linked donations. During the campaign, Larson defended his vote for U.S. military aid to Israel, while Bronin opposed taxpayer funding for offensive military aid but supported defensive measures. Bronin will face Republican Amy Chai in the general election. The district, spanning Bristol, Hartford, and Torrington, is home to 27,800 Jews, representing 3.9% of the population.
