14-term Rep. John Larson ousted by challenger in Connecticut Democratic primary

Democratic Rep. John Larson — who has represented central Connecticut since the late 1990s — lost his party’s primary Tuesday to former Hartford Mayor Luke Bronin, CBS News has projected, after a campaign dominated by debates about generational change.

With just over half of the vote counted at around 10:15 p.m. ET, Bronin led Larson by just under 20 percentage points, or nearly 7,000 votes.
