For what it's worth though. I'd say all of Bush's postive jobs have been outweighed by negatives... usually by the same actions.
The only two really positive things he's done that haven't been counteracted. (Not counting all the negative things he's done that have had no positives.)
1. Africa. He's been basically the best US president for Africa.
2. 9/11. He did a decent job during 9/11.
Of course all the hordes of bad stuff he did likely will wipe out all his good will here... Africa doesn't net much since it's good for other countries not ours... he's arleady ran through his 9/11 good will some would say by starting the Iraq war.
So he's got quite the steep hill to climb if he wants to get above the Mendoza Line that is William Henry Harrison.
He seems to be taking the same hailmary attempt Clinton tried. The "Let's try and get Israel and Palestine to agree to a peace treaty, then i'll be seen as like the bestest president ever, cause nobody can do that.
Well... that ain't goin so well. Peace in 1 year my ass.
