As I said, Graf can afford to run a "take me as I am" campaign. If he fails, might turn out the other GOP candidates might not have done any better. If Giffords wins, she may just be another Karan English fluke. I'm not going to worry too much. ;-)
You might worry that Giffords might become the next Moore. :)
