Also, while Bush was unpopular, he was never at 20%. Not sure he ever even dipped below 30%, though he was definitely close.
He left office at 22%, according to CBS/NY Times Poll. Other polls have it different, but this was the one I had in mind.
Gallup had Bush at 34% in his final day. But he was in the 20%-range for most of 2008.
(I can't post links without 20 posts, but you can find it easily)
Most presidents see their approvals go up when they're about to leave office. Bush's approvals were in the 20s for most of 2007-2008, and much was made of the fact they were so low for so long.
