I wanted to add this video with some meta analysis of Obama's campaign style. But I wasn't very sure about it. Looking at Terence Tao's post on the same topic I got motivated again.
See I mentioned before we can learn a lot from Obama's campaign style for better. Obama's self-criticality, empathy, uncertainty actually add to his focusing ability and thus lead to confidence and success at least as measured by polls and lately by Powell's endorsement. Of course there are 15 more days left and nobody can become complacent now.
Like millions I love (because I feel I can learn from him) the eloquence of Obama for e.g. when asked by someone something like what are you mainly worried about regarding election he said "What keeps me awake at night are not prospects of losing but prospects of winning because there is so much work to be done by the next president."! This again shows his focus! Running an exceptional campaign is only part of the game and he is really targeting to be an exceptional president which America desperately needs one now.
