The Romney campaigns increasingly desperate attempts to dismiss a new study of its tax plan are a pretty good sign that the study is devastating. That isnt to say the campaign is trying to counter it with actual specifics. Performed by the Tax Policy Center, a joint venture of the Brookings Institution and the Urban Institute, the study shows that Mitt Romneys proposal would lead to significantly lower taxes for the rich, and a higher tax burden on middle and lower-income taxpayers. He promised to reduce marginal tax rates by 20 percent, eliminate the estate tax and the alternative minimum tax, and end the capital gains tax for middle income taxpayers, all while not lowering the amount of revenue coming into the treasury. Mr. Romney said he would offset those losses by ending a series of loopholes, but has yet to cite a single loophole he would delete. The study tried to estimate what those loopholes might be. But it found that there simply arent enough loopholes in the tax code to balance the cut in high-end rates that Mr. Romney has proposed. Thus the rich would wind up with a cut, but to offset the loss of $360 billion by 2015, the middle-class would have to pay more when the breaks for mortgage interest, state taxes, education and medical expenses are wiped away. Someone with a calculator was inevitably going to find the many holes in the tax plan, given the tissue-thin level of thought that the campaign put into it, at a time when Mr. Romneys primary opponents were proposing even worse nonsense like the 9-9-9 plan. The campaign has no numbers with which to fight the study because such numbers dont exist. So, instead, its attacking the authors as liberals.
