Romney blunders every time he talks about taxes, and that's because he has no consistent position that he justifies. He's all over the map on the flat tax, for example. He's wide open for criticism on his 47 percent message, and he's getting that criticism. Romney could strongly attack Obama on the economy or on the rise in government debt, but to do that effectively he'd have to propose ways to stop government spending from rising. But his plans call for bigger government. So he blunders on that score too. You would think that a man in his position, with plenty of money and time, could come up with a principled position that makes sense, but this has not been the case.
