I dunno what it is, but something is going on. I can feel it in my bones. Just look at the behavior of Biden and the Clintons of late. Something is just not right.
Biden has always had a tendency to gaffe, but he knows what's at stake here and he's just making too many gaffes too frequently. Today he made a truly boneheaded comment about coal that serves no purpose. And the comment about Hillary Clinton being a better VP than he? It just doesn't make sense.
As for Senator Clinton herself, she pledged to do everything she could to help Obama win, but so far has done almost nothing. Everyone (including me) expected her to be a big asset in fighting back against Palin, but she's said nothing about her, and in fact canceled a planned appearance a few days ago when it turned out both she and Palin would be attending, which she hadn't been told in advance. She says Obama doesn't want her to talk about Palin. Why? Are they avoiding this for some reason I can't see? Saving it for later? What?
Finally, the biggest mystery of all: Bill Clinton. He gave a good speech, almost seeming genuine -- but he's been rather lackluster in his comments about Obama since then. He met with Obama two weeks ago and said he thinks Obama will "win handily", but then has gone out of his way to make nice comments about both McCain and Palin, leading again to accusations that he wants Obama to lose because of what happened with Hillary. This is dumb behavior, and Bill Clinton is no dummy.
Obviously I don't really know what the deal is here. But the behavior of these three is getting so odd that I am at the point of hoping there is some sort of big surprise move, because the alternative is that Obama has lost message discipline with three of his most important surrogates.
