I pledge to the taxpayers of the state of California and to the American people that I will:
ONE, oppose any and all efforts to increase the marginal income tax rate for individuals and business; and
TWO, oppose any net reduction or elimination of deductions and credits, unless matched dollar for dollar by further reducing tax rates.
