Some quotes:
The only moment of physical bravery any of last night's speakers could find in Bush's life was his secret trip to Iraq. "As I think about his leadership," Kerik recalled, "I think of the courage it took for our commander in chief to land on an airstrip in the dark of night, a world away, to be with our troops on Thanksgiving."
Thanksgiving? You mean, six months after we captured the airport and Bush declared victory?
And isn't "the dark of night" normally a term we use to describe the preferred arrival and departure time of people who aren't exactly overflowing with courage?
And more in the article. While demonstrable "physical courage" is not really high on my list for things to look for in a president, that article should induce some delicious head-exploding amongst the more ardent Bush supporters.
