Well, Joe Biden’s saving charm is that he often says exactly what’s on his mind. And that, I suspect, is what is on the minds of just about every Democrat in the country. The Clintons are very pleased, no doubt, with the mass buyers’ remorse that has broken out, even within the Democratic ticket. But no use crying over spilt milk. Biden better figure out how he can help his Presidential nominee. He might start by sticking to an approved script. But the chances of that happening, I would bet, are slim to none.
