Democrats unveiled a proposal Friday that could give California's dominant political party an additional five U.S. House seats in a bid to win the fight to control Congress next year.

California voters in 2010 gave the power to draw congressional maps to an independent commission, with the goal of making the process less partisan. The commission last redrew maps following the 2020 census, and the maps were in place for the 2022 and 2024 U.S. House elections.

Proposed new congressional maps in California could help Democrats flip five Republican seats and bolster around five Democratic incumbents in toss-up districts.
