Bill Frist, Presidential candidate?

There has been plenty of talk for a while now about Bill Frist being a prospective Presidential candidate in '08. I'm not so sure about that anymore. I think something like this is overplaying the Christianity card, and will serve to turn off a lot of support, even amongst the right. Even if Frist's appearance in the telecast involves him saying something completely boring and PC, his association with it is going to creep out a number of moderate and liberal Christians, as well as non-Christians.
