The governor pursued a ballot initiative because Republican lawmakers would not provide the votes needed to reach the two-thirds legislative majority required to raise taxes.

Assembly Speaker John Perez, D-Los Angeles, acknowledged that lawmakers have "limited and difficult choices left to solve the deficit." Senate President Pro Tem Darrell Steinberg, D-Sacramento, said he wasn't surprised by the deficit spike given that state tax revenue have fallen $3.5 billion below projections in the current year.

"We will deal with it," Steinberg said Saturday. "And we know that more cuts are inevitable but we will do our very, very best to save more than we lose, especially for those in need."

Under Brown's tax plan, California would temporarily raise the state's sales tax by a quarter-cent and increase the income tax on people who make $250,000 or more. Brown is projecting his tax initiative would raise as much as $9 billion, but a review by the nonpartisan analyst's office estimates revenue of $6.8 billion in fiscal year 2012-13.
