Obama - mocks McCain for disability

The Obama campaign unveiled a campaign ad mocking John McCain for being computer illiterate.

One problem with the computer dig - McCain CAN'T use keyboards - or tie his own shoes or comb his own hair - for a physical reason: His war injuries.

So it's not a matter of being out of touch. It's a matter of physical disability. Are the Democrats making fun of him for that??? That's pretty low.

McCain actually does know computer technology. He gets around his physical limitations in various ways, including reading e-mails with an aid or his wife and dictating responses for them to type.
