Overview

• Candidates in both parties are preparing district switches contingent on voter approval, with San Diego Councilmember Marni von Wilpert announcing a challenge to Rep. Darrell Issa and several Democrats shifting from targeting Rep. Ken Calvert to Issa, while Republican Kevin Lincoln says he may instead take on Rep. Adam Gray.
• More than $75 million has been raised for a statewide advertising blitz ahead of the Nov. 4 vote on Proposition 50.
• Paul Mitchell, the consultant who drew the proposed lines, says he will not participate in the Yes on 50 campaign and describes the maps as a temporary plan.
• Opponents led by former Governor Arnold Schwarzenegger urge a no vote to preserve the independent Citizens Redistricting Commission.
