That Romney wasn't better prepared for the attacks on Bain and the questions over his taxes is one of the great mysteries of this campaign. That he's not running on a mixture of his time at Bain and his health-care reforms in Massachusetts is one of the great lost opportunities in recent American politics.
This is a good moment for my typical polling disclaimer: At this point in 1980, Jimmy Carter was ahead in the polls. At this point in 1988, Michael Dukakis was ahead in the polls. At this point in 1992, George H. W. Bush was ahead in the polls. But it's not a disclaimer I fully believe.
