I am such a strong admirer and supporter of George W. Bush that if he suggested eliminating the income tax or doubling it, I would vote yes on first blush.
If you or me go to the gas station to fill up our car and it costs us much more than we expected, it will zap our discretionary income. We won't have the extra money to buy that washing machine or new winter coat-all big ticket items that are important to economic growth.
