How can you tell when people have been charmed, bewitched & manipulated by a brilliant charismatic sociopath?

I always see this question from people. Usually they are referring to Obama. If not, I say exorcism would be the best thing. Get your pastor, preacher whoever to get involved and help your friend out. Don't try to experiment with witchcraft yourself have a professional do it. If you do it yourself might make it worse.
