My two cents:
If Dean can somehow (I don't see it as likely, but I thought he was dead after June's MTP interview) comeback even to a respectable tie with Kerry, he will be the 44th President of the United States.
If he does not (I'm guessing he'll come in 5 points behind kerry and tied with clark), he's going to be ridiculed in history as the guy who snatched defeat out of the jawas of victory.
You guys are doing all the right moves now (Diane Sawyer, positive advertising, revamp the stump speech). I'm hoping this beats the "Crazy" speech, but over the next couple of days, we'll have to see what happens. The "crazy" speech is hurting him, but so did MTP. The American people are fickle as hell.
Be strong! Deaniacs, if Dean looses and drops out, get involved in the Democratic party so you can help whoelever wins the nomination. Non-deaniacs, Dean is electable and people have a higher temprement to crap such as negative advertising than we give them credit for. If Dean can be a true underdog...my god...what can happen.
