Found a great post on Milblogs comparing President Bush to some other wartime Presidents in visiting our troops:
How many times did Roosevelt visit the front lines in WWII?
How many times did Wilson visit troops in the trenches in the Ardennes?
How many times did Johnson go to Vietnam?
How many times did Clinton go to Bosnia?
How many times has Bush visited the troops in Iraq?
President Bush is far from perfect. But, he is a good man and I do believe history will look kindly upon him unlike some other Presidents.
