Overview

• George Soros’ Fund for Policy Reform donated $10 million, the largest single contribution to date for Proposition 50, with reports putting the campaign’s haul at about $70 million.
• Proposition 50 would replace the commission-drawn congressional map with a legislature-approved map for upcoming elections if voters approve the measure in November.
• Supporters say the plan could shift as many as five U.S. House seats toward Democrats, positioning California’s map as a counter to Republican gains in Texas.
• Opposition funding is also substantial, with Charles T. Munger Jr. contributing more than $30 million, while other Prop. 50 backers include Reed Hastings and Michael Moritz.
• An Emerson College poll released Friday found 51% of California voters intend to support Prop. 50, 34% oppose it, and 15% are undecided.
