Is Dubya Drinking Again?

There is a great deal of speculation on this. Crooks and Liars provides some video evidence. Sure sounds and looks like Bush has fallen off the wagon. Particularly watch the last bit when Bush steps off Marine One. He normally makes a big deal of his snappy "I was in the National Guard" salute. This time, it looks to me like he's mocking himself. Then watch what he does with Laura. Drunk?
