We've all noticed John McCain having those "John McCain moments.  He gets confused.  His thinking is unclear. When he's asked a question, he hesitates for long periods of time and can't remember the question.   When he does respond to a question, the one about Corsi's book for example, he gives a diffuse inappropriate answer;  "need to have a sense of humor about these things".  He now reads everything off small cards and sometimes it appears that he may not know what's going on.  
Does anyone believe that his condition may be worse thanhis campaign strategists would lead us to believe?
