There's something so appalling, so petty, so small, and yet so right, about a former president and an entertainer going back and forth like this:

In an interview with Matt Lauer, Bush was shown a clip of Kanye apologizing for his 2005 statement. "I didn't have the grounds to call him a racist," West conceded. Blinking at the clip, Bush took the admission in stride. "I appreciate that," he reckoned, before noting that it wasn't just West who derided him post-Katrina. "I'm not a hater, I didn't hate Kanye West...nobody wants to be called a racist," he concluded.

It's surreal. A man who had the launch codes is trading barbs with the dude who P.M. Dawned Taylor Swift. I really can't imagine Barack Obama, in his post-election memoir, trading shots with, say, Ted Nugent. Again, that's part of why I voted for him.
