California Gov. Jerry Brown speaks in support of Prop. 30 at a rally of UCLA students on campus, Oct. 16, 2012
UPDATE 1:47 p.m.: An earlier version of this story contained a PDF of the poll. The Public Policy Institute of California asked for it to be removed and we have complied with the request.
PREVIOUSLY: Two new statewide polls of registered voters show that support for Proposition 30 has slipped to under 50 percent.
A Public Policy Institute of California poll found 48 percent of voters said they will vote for Prop. 30, 44 percent would vote no and 8 percent are undecided. That's down from a September poll that had 52% supporting the tax hike measure that mainly benefits education. The no side has increased from 40 percent.
If passed, Proposition 30 would fund schools by increasing taxes on earnings over $250,000 for seven years, plus increase the sales tax by one-quarter cent for four years. It would also bolster funding for public safety.
A second poll by USC and the Los Angeles Times finds a more dramatic drop in support, with 46 percent of voters who said they would vote for Prop. 30, and 42 percent saying they would vote against it. In September, 55 percent of voters said they would vote in favor of the tax increase.
Both polls find that a competeing measure – Proposition 38 from attorney Molly Munger – still lags behind Prop. 30, with support in the high 30 percent range.
