Charles Krauthammer sees a problem where I see a reason for comfort in Obama's supreme self-regard:
Americans are beginning to notice Obama's elevated opinion of himself [I noticed!]. There's nothing new about narcissism in politics. Every senator looks in the mirror and sees a president. Nonetheless, has there ever been a presidential nominee with a wider gap between his estimation of himself and the sum total of his lifetime achievements?
This is a tricky attack argument - although John McCain is not Mr. Humilty he has earned some of his self-regard.
For the first few months of the campaign, the question about Obama was: Who is he? The question now is: Who does he think he is?
I think Obama has about one core belief, which is that he can talk his way past any audience and any problem. My guess/hope is that he will be a huge disappointment to those hoping for an earnest and committed lefty.
