^ Well, Beavis, now lets add some perspective and context:
Back in 2010, Gallup asked Americans what their retrospective approval rating was for Presidents John F Kennedy through George W Bush. In every instance except for one, the retrospective approval was higher than the final approval was when they left office. Most Republicans, for instance, love to make fun of Jimmy Carter. Carter was the only president of the 20th century to lose re-election after replacing a president of a different party. He left office with a 34% job approval rating. His retrospective job approval rating in the 2010 Gallup poll jumped by 18pt.
Second, Bush’s retrospective approval is the second worst among presidents in the last 50 years ago. To save you doing the math, Carter’s 52% approval rating is higher than Bush’s 47%. Only the Watergate-tainted Richard Nixon recorded a lower retrospective approval than Bush.
