I suggest if you haven't read it you check out this Linda Chavez column, one of her best (imho). She parses Romney's actual remarks and shows that he never even said what the media claim he said, even in an inelegant way. What he did was to list a bunch of groups who make up the 47% who have already decided irrevocably to vote for Obama.
It's possible that some of the confusion came about because about 47% don't pay income taxes, and that was one of the groups Romney listed. But that was coincidental (and I don't buy that it was an honest mistake).
Chavez makes a compelling case that the editing of the surrepticiously recorded video was no less...
