My old friend David Plouffe was in the paper today saying Obama has this thing wrapped up in terms of pledged delegates; that there is hardly any chance at all at losing the pledged delegate count. My advice to my old friends in the Obama campaign is please, please do not get overconfident, do not project overconfidence, do not act like you won this thing. This election is moving in your direction. The dynamics are in your favor. You have the ability to build a lead in delegates that the Superdelegates are not going to change, and would not have the guts to change if they wanted to, but you can still blow it.
This campaign has had more ups and downs than any campaign in my lifetime, and the Obama campaign right now has the momentum and the dynamics in their favor, but friends, you can still blow this thing by getting cocky. The way you blow it is by getting dreamy and taking your eye off the ball the way you did after Iowa. You thought you had it won after Iowa too. You didn't, and you haven't now. Please, for your sake, and for the sake of all your supporters who are so eager for your victory, do not start floating on air. Do not get overconfident, because that is the worst thing that could happen to you.
Update: I have talked to the Obama campaign since doing this post, and they explain that Dave (Plouffe) was just trying to make the case that the delegate numbers look good for them, and that they are in no way getting over-confident. I was glad to hear it.
