Differences.

Bush:

Others inside and outside the administration, however, say the upbeat talk masks disappointment and frustration among many White House staffers, who believe Bush's reputation has been unfairly maligned for a series of calamities -- from the Sept. 11, 2001, attacks to the financial crisis -- that were beyond his control and that he handled well. GOP nominee John McCain's escalating attacks on Bush's tenure have added to the irritation, these people said.

"Everybody kind of wanted to spend the last 100-plus days doing some legacy things, and the financial crisis has thrown a wrench into that," said one prominent Republican who regularly talks with senior White House officials.

"You have a combination of no legacy stuff, a horrible economic mess and the likelihood that Obama is going to win," this person added.

Obama:

ABC NEWS: Was there a worst moment? Or what keeps you up at night?

OBAMA: Well, look, the night we lost New Hampshire was tough. We had been 10 points up, according to the polls going into Election Day and lost by two, and that's one of the reasons why we take nothing for granted in this race and we don't believe those polls. But, you know, the thing that keeps me up is not actually winning or loosing -- it's governing. When I think about things when the lights are out and I'm tossing and turning in bed, its how do we make sure we fulfill the commitments to the American people that we've made throughout this campaign.
