Overview

• Arnold Schwarzenegger, who helped create California’s independent redistricting system, urged a No vote at a USC event and criticized the proposal’s lack of transparency, though he has not recorded ads or raised money for the opposition.
• Republican donor Charles Munger Jr. has contributed $30 million to defeat the measure, while Gov. Gavin Newsom and Sen. Elizabeth Warren headlined a virtual rally urging voters to approve it.
• House Majority PAC has given $5 million to the Yes campaign, with supporters saying the proposed lines could add up to five Democratic U.S. House seats as a response to GOP-led remaps in states such as Texas.
• Campaigns are already shifting: San Diego Councilmember Marni von Wilpert says she will challenge Rep. Darrell Issa in a proposed new 48th District, and Democrats Brandon Riker, Anuj Dixit, and Abel Chavez say they would switch to that race if voters approve the maps.
• Republican Kevin Lincoln is weighing a move to challenge Democratic Rep. Adam Gray under the proposed lines, as GOP strategists warn the statewide ballot fight could siphon funds from individual 2026 races.
