The OC Register points out that the advertising for Prop 30, however, led voters to believe that this wouldn't be the case:
Yet the Prop. 30 campaign led voters to believe that the majority of the money from higher sales and income taxes would go to schools. One TV ad run by Gov. Brown's official Prop. 30 campaign, "Teachers for 30," featured several teachers explaining the need for the money for schools. Then state Controller John Chiang was shown, assuring voters: "With strict accountability, money must go to the classrooms and can't be touched by Sacramento politicians." The spot ended with Gov. Brown positioned in the midst of 17 school kids about age 8, as he implored, "For the students, and for California's future, vote Yes on 30." The kids cheered.
