California voters are being asked to vote themselves a tax hike, in an initiative called Proposition 30.
The measure raises the personal income tax on people earning $250,000 or more for seven years. It also increases the state sales tax .25 percent.
Gov. Jerry Brown said Prop 30 will raise $6 billion a year for schools. He has threatened to slash education funding if voters don't approve it.
"If the 'no' side prevails, billions of dollars comes out of the schools two to three weeks of schooling in Los Angeles, thousands of classes at our community colleges," Gov. Brown told a crowd while campaigning with Los Angeles Mayor Antonio Villaraigosa at a charter school in Inglewood Tuesday.
Kris Vosburgh, with the Howard Jarvis Taxpayers Association, said he opposes the increase.
"It's kind of like they're holding a gun to their own head and they're saying, vote, give me more money or I'm going to pull the trigger," Vosburgh said in an interview with KABC-TV. "Stop trying to blackmail people and saying we won't fund education if you don't give me more money."
Vosburgh and other opponents of the initiative say Gov. Brown is misleading California voters when it comes to where the money will be spent.
"He is contradicting the ballot booklet which says that it can go to all things in the state budget because the money goes into the general fund," Vosburgh said.
