Lets list some:
Kerry: Was a chicken in Vietnam who didn't actually get injured
Wilson: Somehow had his wife send him to Niger, and proceeded to lie about it.
Plame: Not actually undercover, depite refutations numerous times by both current and past CIA officials
Larry Johnson: didn't predict 9/11, hangs out with commie liberals.
Hackett: Wasn't actually fighting in Iraq
The M.O. is becoming quite tiring, and the more obvious and strained it becomes, the more preposterous the next "revelation" is. They really seem to be coming at a more and more rapid pace...
Im sure there are more, anyone care to help out? Predictions for the future perhaps?
