Luke Bronin leads the CT-01 Democratic primary market at 80.5% because he secured the party endorsement at the July convention by a narrow margin over 14-term incumbent John Larson, raised more campaign funds, and positioned his candidacy around generational change and effectiveness against national Republican priorities. Larson, seeking a 15th term at age 78, has emphasized his legislative record and union support while facing the first contested primary in nearly three decades. Recent developments include dueling labor rallies and intensive door-knocking in the final days before the August 11 vote, alongside substantial spending on advertising that has kept the race visible across the district. Minor candidates hold negligible shares, reflecting limited traction in polling and endorsements.
