Most of what this article states is true. Much of it's impact can change in the twinkling of an eye. I don't begrudge Bush success. The nation is better off for that success.
I am thankful that Bush's demeanor is so much different than Clinton's. However, I'd rather make certain observations regarding his past year and forgo the predictions for the future. We have seen what can happen to a 90% approval rating.
Bush's full impact will not be known until he has been out of office for a few years. Even then his administration will not stand the test of time until a decade or more has passed. I still feel that Clinton's legacy could blow up sky high. If it can and may even after his administration is over, I think it's best to wait some time before writing glowing reports of Bushes overall impact on history.
