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

The new, partisan maps come on the heels of Gov. Gavin Newsom’s launch of California’s redistricting campaign on Thursday, an effort he touted as meant to favor Democrats in California in the upcoming midterm elections as a counter to similar efforts in Republican-led states elsewhere in the country.

The measure, which would appear on the ballot in the state in November if lawmakers approve it, is a response to Texas Republicans' mid-decade redistricting push.
