My friend has his PhD in psychology & has maintained a successful practice for more than 20 years -- while you can't really make a 100% sure diagnosis without evaluating someone in person --he pegged Obama as having sociopath tendencies back in 2008 & he maintains that assessment as he's watched Obama over last 4 years . The problem others have seeing it is the word "psychopath" -- the word itself brings up images of serial killers, etc. but that isn't what it means. While most serial killers are psychopaths, not all psychopaths are serial killers. The markers of a psychopath are lack of empathy, shallow emotions, egocentricity, and superficial charm used to manipulate others -- basically, every trait of Obama's cited in this article.
