Not at all. Claiming McCain can't lift his arms above his shoulders was refuted by posting a picture of him doing just that.
No it was not. his arms are out stretched And if you look at him, he is obviously having trouble with that. Remind us when you became a Doctor and have reviewed his medical records?
One must keep their forearms up and away from their body. Which requires work from the shoulders and the arms. Even resting my wrists on the desk does not change that and one can not remain in that position to type well at all.
You keep up the attack though, and advise Obama to keep running the Ad. I am sure it will be a winner for him.
