Obama has no interest in being President, he just wants to be a celebrity.
I partially agree, but IMHO his grandiosity goes well beyond being a celebrity. I think he truly believes that he is the one who will reshape America into a socialist nation, and right all wrongs. When he said ‘we will look back at this as the moment when the oceans stopped rising’ (or whatever the quote was) he appears to really have believed that. That's a boatload of grandiosity.
