California Democrat flips final House seat, dealing Republicans narrow majority

ABC projects that Democrat Adam Gray will win the race for California's 13th Congressional District, unseating incumbent Republican John Duarte and flipping the final unresolved seat in the 2024 election.

With all 435 House races projected, ABC News estimates Republicans will hold 220 seats and Democrats 215 in the 119th Congress.

But it’s not clear how vacancies -- or, illness or other absences -- will impact the day-to-day division of power when the House convenes on Jan. 3.
