For anyone concerned with how the final convention vote may come down on the Democratic side with the superdelegates possibly holding the decision in their hands, there is a petition from MoveOn that you can sign that says you want the superdelegates to vote the way the majority of the other elected delegates have gone. I'm not sure how much effect this will really have (and it seems like public pressure is already mounting so that it might go down that way anyway), but if you like petitions, you can find it here:
