An overly-enthusiastic hand-shake aggravated an old injury.
If I were her, I'd be wearing the cast when among the public for the rest of the campaign. It will at least discourage someone from doing it again.
Bob Dole's right arm was paralyzed in an war injury, and he carried a pen in that hand to discourage people from trying to shake it.
I have a question of the board:
All due respect to our next President, John McCain, I note in the photos that he seems to have trouble raising his arms a little. Is that because of what he went thru during the Vietnam War? It was what I thought.
God Bless John McCain and Sarah Palin and their families.
