Avlon notes an interesting wrinkle in one possible tax deduction Romney might or might not try to remove: state taxes. It would hit the residents of blue states hardest. But also – critically – some swing states: Colorado, Iowa, New Mexico, North Carolina, Ohio, Pennsylvania, and Virginia. Personally, I think, like John, that any pol prepared to state a tax deduction he would remove deserves praise. But what this kind of thing shows is that picking and choosing tax deductions creates huge political problems, as they affect this or that constituency disproportionately. Hence my support for a massive, sweeping end to all of them, if necessary, to raise revenues and reduce rates.
The smaller-bore you are, the more likely you are to get bitten to death by particular interests. The bigger you are, the more able to leverage the public good against private advantage.
