I think Peter Wehner hits the nail on the head in his comments at NRO:
"In my judgment, what happened Friday will begin to cement an image about Obama that is negative — that his supposed “golden touch” is very nearly the opposite; that his rhetorical talents and appeal are vastly overstated (he delivers a major health-care speech to a joint session of Congress and it does nothing to move the needle; he then makes a personal appeal to the IOC and Chicago is dropped from the list in the first round); and that he is a surprisingly weak figure who is easily rolled by Democrats on Capitol Hill, by adversaries around the world, and, now, by the IOC."
