He's definitely not a loser. He has little opposition when he runs in the district, and he's pretty much assumed to be the one who will inherit John Warner's senate seat.
Granted. Davis is a RINO, but you're correct that he's no loser.
He is, however, out of the party mainstream. I would take issue with your statement that he's "assumed" to be the heir to the Warner Senate seat.
HE may assume that. But it's not coming from the rank and file GOP.
