Will Bush break the pattern?

Here's a link to my most recent piece for antiwar.com. In it I note that President Bush having such low approval ratings right now could be viewed as unusual, in that when historians are asked to rate presidents they almost invariably choose wartime presidents as "great or near-great." In hoping Dubya doesn't recover in the eyes of historians (as Truman did) I also hope against hope that the dire results of this current war lead historians to reassess whether starting a war or even leading the country during wartime are true measures of greatness. Upholding the Constitution -- apparently a much more difficult job, considering how infrequently it has been done -- might serve as an alternative measuring rod.
