The real fact is, Obama knows almost nothing. His real reason for talking so much dribble is to avoid having to answer intelligent questions which would show how truly stupid and ignorant and incompetent he really is.
Good point, I think he does fear unscripted or difficult questions because he knows somewhere in that pea brain that he is just another Affirmative Action incompetent. Once this becomes widely evident he is toast....it will not take much longer....and 200 milion voices will scream, He MUST GO!
