Like Kevin, I've never quite understood why Hillary Clinton would want the vice presidency. First, the job, as he argues, has serious shortcomings, and there's every reason to imagine she'll be more powerful as the best known Senator in America. But second, by all accounts, she's certain Obama will lose the election, and it's never a good idea to be associated with a losing ticket. Conversely, if she goes back to the Senate, works hard for Obama, and he loses, she can easily assume a de facto role as leader of the Democratic opposition to John McCain, which would set her up more naturally for a run in 2012, if indeed that's what she wants.
