Republicans should deep six Tom Coburn as soon as possible:
I’ve argued that Republicans should be willing to consider increases in revenue -- not through higher tax rates but through eliminating tax earmarks, such as that for ethanol, and other expenditure that misallocates capital.
"Tax earmarks ... and other expenditure that misallocates capital"?
Read "tax expenditures," better yet, "tax loss expenditures."
Like your mortgage interest deduction, your charitable contributions deduction, your property tax deduction, your state and local income taxes deduction, and so on. All these benefits of the tax code misallocate capital, if you're a politician running the business of government, and you are just its employee.
That's who Tom Coburn is, the boss. He wants more of your hide.
