Rep. John Larson ouster makes 2026 a record year for Democratic primary losses

Rep. John Larson (D-Conn.) was defeated in his primary election on Tuesday by former Hartford Mayor Luke Bronin, according to the Associated Press. This marks the seventh House Democrat ousted in their primary this year, a record number since the 21st century began. Bronin's challenge against Larson followed the Connecticut congressman's apparent seizure during a House floor speech, which he later attributed to a complex partial seizure.

The state Democratic Party supported Larson, while Bronin garnered backing from the state Democratic Party and the rest of Connecticut's congressional delegation.

Bronin, 47, outpaced Larson in fundraising, collecting $3.1 million as of July 22 compared to Larson's $2.7 million over the same period. Outside support was also a significant factor, with Bronin receiving over $1 million from VoteVets, a group advocating for Democratic military veterans, while Larson's top outside spender, Defend the Vote, contributed just over $500,000.

Bronin's campaign emphasized the necessity of generational change in Congress and the Democratic Party, stating in an ad that while Larson is a "good man," his time in Congress since the 1990s has made further change "too high" to maintain. Both candidates sought to highlight their progressive credentials, a trend seen in numerous safe-seat Democratic primaries where progressives are increasingly favored.

Larson joins a group of older Democrats who have lost to younger primary opponents this year, including Reps. Al Green (D-Texas), Diana DeGette (D-Colo.), Adriano Espaillat (D-N.Y.) and Shri Thanedar (D-Mich.). While Green and Larson both positioned themselves as committed progressives against opponents focusing on their age, DeGette, Espaillat and Thanedar lost to challengers running to their left.

Other members aged 70 or older, such as Reps. Doris Matsui (D-Calif.) and Mike Thompson (D-Calif.), face November run-offs against younger Democratic rivals.
