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

As the battle over partisan redistricting mounts, Democrats in California unveil a congressional map that could yield up to five new seats for their party, countering Texas' plan for five GOP seats.

A day after Gov. Gavin Newsom announced plans to redraw California's congressional districts, a proposed map of the new districts was released.

Gov. Gavin Newsom asked legislators to approve a Nov. 4 special election over the "Election Rigging Response Act," which would give voters a say on whether or not to temprarily change congressional maps.

“We are entitled to five more seats” in Texas, Trump insisted Tuesday in a CNBC interview. He pointed to California’s existing maps, which are drawn by an independent commission unlike the Texas maps crafted by a partisan legislature: “They did it to us.”

The California Assembly on Friday night shared a map that the California Legislature may consider as the state moves ahead with a plan to redraw its congressional lines if Texas moves forward with its redistricting plan.

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.

A partisan move by Texas to redraw its congressional maps in the middle of the decade to secure five more GOP seats in the U.S. House set off a clamor to replicate the effort in statehouses

Missouri's congressional map earned an average score, or "C," for both, with an average compactness score of 0.456 (just shy of the 0.5 needed to earn a "B") and nine split counties. The state received an overall "A" score from the study, one of just 21 states to do so.

Ohio lawmakers will start drafting new congressional districts, with the Equal Districts Coalition pushing for fair maps.
