Luke Bronin, 47, the former mayor of Hartford, leads Connecticut’s 1st Congressional District Democratic primary as votes are counted, capturing 51.2% of the vote and challenging 14-term incumbent Rep. John Larson, 78, in one of the state’s most closely watched races.
The primary represents Larson’s first serious challenge since his initial election in 1998, when he won with 46% of the vote. Bronin, the endorsed candidate of Connecticut’s Democratic Party after winning the state convention in May by just 10 votes, has outraised and outspent Larson during the campaign, according to reporting from PBS NewsHour.
The race centers on generational change within the party. Bronin has questioned whether Larson, now 78, remains willing to take on the Trump administration forcefully. He secured endorsements from prominent figures including former Transportation Secretary Pete Buttigieg, according to CT Public. Larson, who taught history and coached football before entering Congress, has built his career around Social Security advocacy and has not faced a primary opponent in nearly three decades.
Connecticut’s 1st Congressional District primary is part of a broader 2026 trend: nine House incumbents have now lost their primaries this election cycle, the highest number outside a national redistricting year since 1970, according to NBC News reporting from August 8. The wave reflects mounting pressure on older Democrats to step aside for newer voices, even in districts Democrats have long controlled.
The primary also includes state Rep. Jillian Gilchrest and Hartford Board of Education member Ruth Fortune as candidates. Bronin will advance to face the Republican nominee in November’s general election if he wins the Democratic primary vote count.
