SAN FRANCISCO (Reuters) – California lawmakers should reject Gov. Arnold Schwarzenegger's plan to sell $6 billion in revenue anticipation warrants to raise cash for the state government as it faces a $21.3 billion budget gap, the state's budget watchdog office said on Thursday. The California Legislative Analyst's office said in a report that Schwarzenegger's plan for the short-term debt would be a "terrible precedent and a poor fiscal policy," and "presents serious legal concerns."
