His left side of his mouth is drooping down, it's as if he had a stroke or something. You'll recall that in the past few weeks the White House announced something about Bush not getting his annual physical until after the election (something like that). I think there's something wrong with him.
Note this Reuters story from one week ago:
The White House cited Bush's heavy travel schedule for his decision to delay his annual physical exam, which usually takes place in August, until after the election.BS. Numerous observers here with me, and in the chat, said they saw drool at the beginning of the debate (again, I'm serious). There's something wrong with his face tonight and he's not admitting it.
White House spokesman Scott McClellan said Bush's doctors "felt it was perfectly fine to do it later this year... The president is a very active person. He's in great health."
