Bush didn't accomplish a single major domestic policy initiative in his first six and a half years (and four of those were with a completely friendly congress, and six of those years were with a friendly house and a split Senate). After the passage of his education plan (the No Child program), can anyone name one major domestic policy change that Bush has pushed for and instituted: social security- nope, crime- nope, transportation- nope, health care- nope, immigration- nope, anything else- nope.
Bush is the most reactive President in the history, he has been unable to pass a single major initiative that he planned through Congress. I would have tried in my first six and half years to do something before a disaster hit. I don't hate Bush, but name something that he has planned, completed, and gotten passed. He's responded to issues, but has not taken any initiative on his own and shouldered the political weight.
We can judge him by a lot of different standards: success or failure, good or bad, legal or illegal. Bush's reaction-only presidency might have been successful or good; that's for you to decide.
