Bill Clinton

Bill Clinton still has it -- the man is the consummate politician: smart, witty, folksy, able to take an audience and make them roar. Whether you agree with him or not, I think you have to admit that was a hell of a speech. And I do believe he was subtly (or not so subtly) making a case for moderate Republicans to jump ship if they're feeling their party has been hijacked by those on the far right.

Makes sense, since in my view Obama's essentially what would have been a progressive Republican or a Democrat on the extreme right side of the party a few decades ago.
