The campaign against Proposition 77 now has additional $4 million in its war chest, according to the Los Angeles Times. The donation came from movie producer and real estate heir Stephen Bing, and will be used to fight the ballot measure that would take control of redistricting in California from the state legislature and place it in the hands of a committee.

Supporters of the measure, including several wealthy Silicon Valley entrepreneurs, have raised about $5 million. Gov. Arnold Schwarzenegger is backing the measure and is expected to spend heavily to promote it.
