Romney's latest ambiguity answers nothing:
I did go back and look at my taxes, and, over the past 10 years, I never paid less than 13 percent.... Every year, I paid at least 13 percent, and if you add in, in addition, the amount that goes to charity, the number gets well above 20 percent.
What kind of taxes? Federal? State? Local? Sales? Payroll? Property? Investment?
Given Romney's Nixonian shiftiness, was it carelessness that caused him to say merely "taxes," rather than federal taxes? Or was it extreme care?
