56 percent of people poll think that Obama is doing "the same" or a "worse" job than Bush. Of course the White House might spin the very same poll, finding that 65 percent percent say Obama is as good as or better than Bush.
While more people rate Obama "better" than they do "worse," the poll is bad news for Obama. Those who rated him "the same" think he's doing a similarly terrible job.
It could be argued that saying Obama has been about the same as Bush is also a negative evaluation, given that Bush left office with low approval ratings and Americans generally did not judge his presidency to be very successful.
Indeed, those who say Obama has been about the same as Bush generally view Obama negatively, with 27% approving and 62% disapproving of the way Obama is handling his job as president.
He also pales in comparison to Clinton. Only 15 percent think of Obama as a better president.
