The Obama camp can’t be happy that the major political story of the past three days hasn’t been Joe Biden but rather the fallout from Obama’s refusal to select Hillary Clinton. Of course, we don’t know what might have happened otherwise, had he chosen her; the story then might have been the possibility of Obama’s being overshadowed by the one-two punch of Hillary (tomorrow night) and Bill (Wednesday night). However you perceive it, though, the Biden addition has been a complete bust as a news event. The onus is now on Biden to deliver a killer speech on Wednesday and thereby allow Democrats to feel something other than disappointment at his elevation. Whatever a Hillary pick would have generated, it wouldn’t have been disappointment.
