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

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 Democrats on Friday released their redistricting proposal, aiming to produce up to five additional Democratic seats in the US House in response to Texas Republicans’ mid-decade redrawing of lines at the behest of President Donald Trump.
