Only problem -- for Obama, that is -- is that McCain can't use a keyboard because of the wounds he sustained in service to his country. According to a 2000 piece in The Boston Globe:
McCain's severe war injuries prevent him from combing his hair, typing on a keyboard, or tying his shoes.
Oops. Think of it this way, Barack: McCain's willingness to risk that injury you've tried to ridicule is what gave you the freedom to serve as a "community organizer."
