No doubt as more details come out they’ll be plenty for both sides of the political spectrum to point fingers at, but think about this for a second. The President of the United States has his feelings hurt by something written in a book by one of the nation’s governors and he brings it up during a meeting with said governor.
I can’t find a link but I seem to recall early in George W. Bush’s first term Jimmy Carter said some nasty things about him. When they next met, Carter sheepishly said he was sorry about that and Bush’s reaction was akin to “Dude, don’t worry about it.”
UPDATE: Ace’s take.
