The CW going into the Democratic primary debate about to air on MSNBC is that we should be watching whether Barack Obama attacks Hillary Clinton tonight, particularly on Iraq. Chris Matthews says, "If he won't accuse her of blowing it...of making the worst decision in the world...than why should the American people reject Hillary if he won't do it?" Now he says, "I'm warming up to Hillary these days." Keith Olbermann replies, "I don't have anything to warm up from!" Not sure what he means. Has Olbermann always been really hot for Hillary? Anyhow, I'll be paying attention to all this, and much more substantive issues as well. Here we go. The first question is on how to end the war, and Obama says, without confronting anyone, "I opposed this war from the start." --Dana Goldstein
