They don't seem to have anything positive to say about their own candidate, and little but [http://www.baltimoresun.com/news/opinion/oped/bal-op.mccain10oct10,0,75… hate to unite them]. There appears to be a hard core of right-wing McCain supporters who see nearly a decade of Republican power slipping away and are full of inchoate rage at their inability to stop it. I wouldn't be surprised at all to see some of these people turn to actual violence.
