The author you quoted is factually wrong. Sure there is short-term history, but short-term history changes quickly. What will matter in the long-term is
long-term history. Many presidents who look very different after historians have been able to access the various files/notes (etc) in the president's library/archives. That process will take years to even really get started. There are more than a few presidents who looked bad at the end of their term but who, over time, have had their image improved through study of their records and the unfolding of history. George W Bush need not worry himself with short-term history. The only thing that will matter is long-term history. How will Americans in 25, 50, 100 years view Mr. Bush? That is the issue. The answer to that question will be determined by the history found in his library and how his policies played out in the long term. It is simply too early to give any sort of final judgment on the Bush administration.
from article said:
George W. Bush will leave office next week as a president whose eight years in office are widely seen as a nadir from which it will take years to recover.
==That is a political statement based on the author's opinion. It is not historical fact. How things are "widely seen" is a questionable statement since it really depends upon who is being asked. The author is welcomed to his opinions, be they true or false, but his opinions are not facts. Regardless of how much of a success or failure each of us believes the Bush years have been, none of us can make the final call. That is the job of God and history.
