I proceeded to make a checklist as to who had what trait. When I was finished Hillary and Bill shared all but four traits. The four that Hillary did not have Bill did. In other words, Bill and Hillary make a perfect psychopathic couple. Together they share all the traits that indicate a psychopath. Most psychopaths don't have all the traits.
Now for Obama I have not conducted the same type of study, however from what I do know he is a perfect amalgamation of Bill and HIllary.
