Poof

Review & Outlook: Mathematically Possible - WSJ.com: "Scholars at the American Enterprise Institute examined what happens to the Tax Policy Center math when this error is corrected. AEI economic research associate Matt Jensen found that "Both of these exclusions largely benefit the wealthy, and, according to the Treasury Department, added together their repeal would net upwards of $90 billion that could be redistributed to lower-income individuals. That would go a long way towards balancing the supposed $86 billion windfall for the rich and tax hike on the middle class and poor, and it could make the impossible suddenly possible."

The AEI analysis warns that these numbers change from year to year, but it concludes that by eliminating these two deductions and a few other smaller ones, Mr. Romney can make his math add up. In other words, poof, no tax hike on the middle class."
