Are politicians psychopaths

I was reading an article in Scientific American that stated that traits that are common among psychopathic serial killers, a grandiose sense of self-worth, persuasiveness, superficial charm, ruthlessness, lack of remorse and the manipulation of others, are also shared by politicians. I agree completely with the article. Dosent make any difference what group the politician is part of. Do you agree or disagree? Let me edit this, someone was reading me the article. According to some on this site I'm not smart enough to read it myself.
