Head to Heads

New polls show John Edwards and Barack Obama both crushing either Rudy Giuliani and John McCain, while Hillary Clinton is in tight races with both of them, and Mitt Romney gets demolished by everyone.

Drawing lessons will be left as an exercise for the reader. I have to say, though, that if Romney's going to be a kind of fake conservative and really unpopular, that it's hard to see what the rationale for his candidacy is supposed to be.
