Former Hartford Mayor Luke Bronin defeated 14-term U.S. Rep. John Larson in Connecticut's 1st Congressional District Democratic primary on August 11, 2026, ending Larson's nearly 30-year hold on the seat. The race became a proxy fight over generational change in the Democratic Party, and a test of Sen. Chris Murphy's political capital after he endorsed Larson amid mounting talk of a 2028 Murphy presidential bid.
