historians bob caro, h.w. brands and journalist george packer at hampton institute to talk about how history will judge president obama compared to past presidents. this runs an hour and 25 minutes. i realized the bumper sticker was a little worn, a little of used by the elements, but in fact, of course, it was quite legible and still very red, white, blue. not to be too silly or clip, but i did wonder if it was some kind of metaphor for what this president was going through. how successful is he? how bruised, in fact, is he? how, to paraphrase it koch, is he doing? i wanted to started out by saying all so if i were president obama i am not so sure i would want to be here this afternoon to hear the answer. with all due respect, the idea of being discussed and bisected by the biographers of lyndon baines johnson and franklin delano roosevelt and by a new yorker writer who has said, i quote, he, mr. obama, is not that messianic figure many of his supporters think he is, i think that would be daunting to anyone.
