In 1990, voters approved Prop 111 (laughingly titled "The Traffic Congestion Relief and Spending Limitation Act of 1990"), which doubled the California excise tax on gasoline over 4 years:
Prior to 8/1/1990 = 9.0¢/gallon
8/1/1990 = +5.0¢/gallon
1/1/1991 = +1.0¢/gallon
1/1/1992 = +1.0¢/gallon
1/1/1993 = +1.0¢/gallon
1/1/1994 = +1.0¢/gallon
_______
18.0¢/gallon
And don't forget to add on the sales tax, which is also applied to the above excise taxes themselves(!).
The first question out of anyone's mouth when somebody says, "We need more money for [insert popular thing here]" should be, "What the hell happened to all the money we've already given you?" In this particular case, "Where the hell is all the Prop 111 money going?"
Former Gov. Davis borrowed out of the highway fund (unconstitutionally, of course) in a futile attempt to balance the budget.
He also robbed the teacher's retirement fund, the pop bottle recycling fund, and who knows what else.
