Trader consensus slightly favors former Hartford Mayor Luke Bronin at 47% over longtime incumbent Rep. John Larson at 38.5% in the CT-01 Democratic primary, driven by Bronin's dominant fundraising—$1.8 million cash on hand versus Larson's $1.1 million from Q1 reports—and high-profile endorsements like Pete Buttigieg and current Hartford Mayor Arunan Arulampalam, amplifying calls for generational change against the 77-year-old Larson. Larson's recent union backing, including 11 new endorsements, and incumbency advantages maintain the tight contest amid scarce public polling since his favorable March internal survey. The race stays competitive with minor candidates like Ruth Fortune and Jillian Gilchrest distant; Monday's state Democratic convention endorsement vote, potential debates, or fresh polls before the August 11 primary could create separation.
