When income tax revenues fell billions of dollars short of expectations last month, modest gains in other revenues were wiped out, leaving the state running well behind, Controller John Chiang reported Friday. "Four months of positive receipts were erased in the last 10 days of April," said Chiang. "Because a surge in revenues has not come, the governor and Legislature need to move quickly and forge the consensus needed for a balanced budget. Any delay will only limit their options and expose already struggling Californians to greater harm."
