Former Hartford Mayor Luke Bronin surged to the top of trader consensus at 64.5% implied probability after securing the Democratic Party endorsement over 28-year incumbent Rep. John Larson at the May 11 district convention, prevailing 51%-49% on the second ballot in a dramatic upset. This victory provides Bronin with key organizational support, ballot access advantages, and momentum heading into the August 11 Democratic primary for Connecticut's 1st Congressional District, a safely blue seat. Larson, polling ahead earlier this year and backed by House leadership, retains incumbency advantages and trails at 33.5%, while challengers State Rep. Jillian Gilchrest and others lag far behind amid Bronin's fundraising edge and endorsements from figures like Pete Buttigieg. Upcoming debates and voter turnout among urban and suburban blocs could shift dynamics.
