I realize this is a minority view, but I thought it was boring and unmemorable, good mostly because it didn't make any real news. (Bill did his part to elect Barack Obama back in South Carolina.)
Two astute points from Stephen Green:
Clinton very pointedly mentioned crushing "credit card debt." And Biden is pretty much a wholly-owned subsidiary of Delaware's many credit card companies. Clinton knows that. The media know that. And pretty soon they'll remind you of it, too....
Michelle Obama noticed, too. When Michelle really smiles, she lights up the entire Pepsi Center. All she gave Clinton was her tight, closed-mouth smile.
