I tend to agree with you - Dean is probably on his way out - The only thing he knows to do is get more angry - Which is all they have because truth and facts are no longer allies to them at all - In fact they are enemies to the left (which just continues to breed anger out of them).
They are simply a party of intellectual children.
Dean on his way out? Please! NOOOOO! I want him to keep the job he has now and that he is doing so well. No one could do better. Well, no one intelligent and sane, that is.
