HOST: Two new polls show support for Jerry Brown's Proposition 30 slipping, and today the Governor stood with San Francisco business leaders supporting his November tax measure. KQED's Scott Shafer was there.

SCOTT SHAFER: Proposition 30 would raise income taxes on the wealthiest Californians for seven years and boost the sales tax by a quarter cent for four years. If the measure fails it will trigger $6 billion in state spending cuts, with most of it coming out of public education.

At a San Francisco press conference today, Gov. Jerry Brown framed the choice this way: "It's hurt the schools or take a little money from people who can well afford it. It's so obvious that it is a little puzzing that the polls aren't a little higher."

Brown also endorsed a lawsuit aimed at forcing public disclosure of the Arizona donors who made an anonymous contribution to the No on 30 campaign recently. Brown called their $11 million contribution "probably the worst abuse of California's election laws." I'm Scott Shafer KQED News.
