Will there be blood on McCain's hands?

If the worst happens and some right-wing nut takes the not-so-subtle hint from the McCain campaign that Barack Obama is "dangerous" and "not one of us," there will be blood on John McCain's hands. And, let's be clear.....the "worst" will be an assassination attempt on Barack Obama. Everybody in the media is afraid to say this out loud, but we all know it's the 800 pound gorilla in the room.
