Recent first-quarter 2026 fundraising reports propelled former Hartford Mayor Luke Bronin to the top of trader consensus at 47% implied probability in the Connecticut's 1st Congressional District Democratic primary, as he outraised 14-term incumbent Rep. John Larson for the third consecutive quarter—$511,000 to $452,000—with $1.8 million cash on hand versus Larson's $1.1 million, funding Bronin's early TV and digital ads advocating generational change against the 78-year-old congressman. Larson counters with high-profile endorsements from House Minority Leader Hakeem Jeffries, Sens. Richard Blumenthal and Chris Murphy, and a January internal poll showing him leading 49%-26%, yet traders prioritize Bronin's financial edge ahead of the May district convention, where 15% delegate support secures primary ballot access on August 11 or petitions suffice otherwise. State Rep. Jillian Gilchrest and others lag with far less funding.
