John Larson primary election defeat in Connecticut on Tuesday made the longtime Democratic Rep. the 10th House incumbent to lose a primary this cycle. The result adds to an unusually high number of House incumbents falling in primaries and leaves the party’s internal push for newer leadership in sharper view.
Larson’s loss is part of a pattern that has now reached 10 House incumbents this cycle. That is the central count in this race: one primary defeat in Connecticut moved the total up again.
