I expect W will rise to the mid-50s or low 60s before he's finished. Obama's actions certainly help him, as well as the tremendous class he's shown since leaving office like refusing to criticize Obama. It certainly makes past Democratic President like Clinton and Carter look like jacka$$es in comparison.
Bush wasn't a great President by any means, but he's far from the worst ever. I think many people are beginning to realize a lot of the things that happened under his watch could not be avoided regardless of who was in office at the time.
I hope not. If George W. Bush -
George W. Bush - is in the low 60s ever again the planet is doomed.
