Just to defend Krauthammer as not clueless, he does state in this article “That’s why for an hour I am putting aside my cynicism and crediting him either with sincerity or, if you like, the grandiosity of a second term president who thinks he is omnipotent.” Krauthammer is, in essence, accurately calling the Marxist a narcissist.
Thank you-Krauthammer is a psychiatrist-he doesn’t just play one on TV-he knows very well how to call someone a narcissist without saying the word, and as you say, he has referred to Obama as being one several times.
