Jonah Golberg says John McCain probably can't use a computer because he was a POW:
Does anyone know why McCain doesn't use a computer or email? As a couple readers suggested to me, it might be because his injuries prevent it. I mean he can't lift his arms much higher than his chest and it looks like he has all sorts of other mobility problems with them. Maybe he can't type or use something like a blackberry. I don't know. But I hope the Obama campaign found out before they played the granpa Simpson card on McCain. I'd hate for Obama to be mocking a veteran's disability to score cheap points.
