Democratic Rep. John Larson lost his primary in Connecticut’s 1st Congressional District to former Hartford Mayor Luke Bronin, who ran on a message of generational change. The result makes 2026 a record year for Democratic primary losses among sitting incumbents.
Bronin’s win adds to a broader pattern this cycle of long-serving House Democrats being unseated by younger challengers, part of a wider debate within the party over generational turnover heading into the general election.
Larson’s ouster was one of several primary results being closely watched Tuesday night as Connecticut voters weighed in alongside a slate of other closely contested races around the country.
