Bronin defeats 14-term incumbent Larson in Connecticut Democratic primary

Luke Bronin, the former mayor of Hartford, defeated 14-term incumbent U.S. Rep. John Larson in the Democratic primary for Connecticut's 1st Congressional District on Tuesday, earning over 50% of the vote according to the Associated Press, which called the race at 10 p.m. Larson received approximately one-third of the vote, while State Rep. Jillian Gilchrest took roughly 8% and attorney Ruth Fortune approximately 5%.
Bronin, 47, served as Hartford's mayor from 2016 to 2024. Before that, he worked in the Department of Treasury under President Barack Obama and as general counsel to former Connecticut Gov. Dannel Malloy.
In his acceptance speech, Bronin addressed economic inequality, health care costs, and criticized the Trump administration's domestic and foreign policy, calling for a 'factory reset' of the Democratic Party.
Larson, 78, was first elected in 1998 and is currently the ranking member of the Social Security Subcommittee. He is among a group of older Democratic incumbents — including Reps. Al Green, Diana DeGette, Adriano Espaillat, and Shri Thanedar — who lost to younger primary opponents this year.
In the final weeks of the campaign, Larson used attack ads portraying Bronin as aligned with wealthy donors and corporations. The two men had previously praised each other, with Larson calling Bronin 'the best mayor in the country' in 2023 and Bronin calling Larson 'the best member of Congress this district could ever ask for' in 2022.
Both men called for Democratic unity on Tuesday night. Larson delivered his concession speech at the Connecticut River Academy at Goodwin University in Hartford.
Gilchrest, a social worker elected to the State House in 2018, chairs the Human Services Committee and campaigned on reproductive freedom, affordable health care, support for working families, and campaign finance reform.
Fortune, who came to the United States as an undocumented child from Haiti, is a member of the Hartford Board of Education and an attorney at Wiggin and Dana. She campaigned on universal health care, increased funding for housing and education, and immigration reform.
According to the most recent Federal Election Commission data, Bronin and Larson were the largest fundraisers and spenders in the primary, with Gilchrest and Fortune hundreds of thousands of dollars behind.
Connecticut's 1st Congressional District covers roughly 721,000 people according to the most recent U.S. Census data. Bronin will face Republican nominee Amy Chai in the November general election.
