Overview

• Republican legislators filed a new petition asking the California Supreme Court to keep Proposition 50 off the Nov. 4 ballot, arguing it violates the state’s single-subject rule and usurps the independent redistricting commission.
• The court rejected an earlier GOP challenge last week on timing and notice grounds, and some election-law scholars say the latest claims are unlikely to succeed.
• President Trump said he will direct the Justice Department to sue over California’s plan, but the administration has not specified the legal basis or filed the case.
• Proposition 50 would suspend the state’s redistricting commission and put a Democratic-leaning congressional map to voters that backers say could add up to five seats.
• Texas Republicans advanced a mid-decade map projected to add five GOP seats and now face Voting Rights Act litigation, heightening a national fight that polls show most voters oppose.
