'Joe is Right'

Another kind of piling on -- the good kind -- happened at the Democratic debate in Las Vegas, as the candidates gushed about the wisdom of one of their own: Joe Biden. Over and over, Biden's rivals concurred with the Delaware senator as they gave their own answers. So much so, in fact, that the campaign stitched together a video called "Joe is Right." (Meaning, presumably, he is correct, not moving in a new partisan direction).
