“I find it amusing that those who helped to authorize and engineer the biggest foreign policy disaster in our generation are now criticizing me for making sure that we are on the right battlefield and not the wrong battlefield in the war against terrorism.” The attacks grow more pointed among the Dems at last night’s AFL-CIO debate (which I missed), and it sounds like both Obama and Edwards got in some good zingers. (Edwards: “The one thing you can count on is you will never see a picture of me on the front of Fortune magazine saying I am the candidate that big, corporate America is betting on.“) And yet, a new poll finds Senator Clinton widening her lead over Obama to 18 points and enjoying huge advantages in big states like Ohio, Florida, and Pennsylvania. Hmm. Is the race already over? The inveterate pessimist in me says definitely maybe, but let’s remember, Howard Dean was looking pretty solid in August of 2003. We have a ways to go yet. (I mean, the critical Jolie and di Caprio endorsements are still up for grabs, for example. And Obama does have Bourne and Clooney locked up.)
