Well at least Arnold has vetoed some legislation. If a Democrat was in office we would have had a tax increase again, a repeal of prop 13, and drivers licenses for illegals.
Sorry, you don't have your facts straight.
A tax increase would require Republican complicity in the State legislature. A repeal of Prop 13 would require a State Constitutional Amendment, with voter approval. Driver licenses for illegals were about to be repealed anyway by referendum when Arnold signed nearly unanimous legislation repealing SB-60.
