I don't think I'd say most, but a fairly large number of them do. These are the McCain voters of 2008 and the Romney voters of today.
My wife's family is full of them.
Freepers who spend all their time in the 'bubble' run the risk of being the conservative equivalent of Pauline Kael. . . . "I just don't see how McCain could have won the nomination. Nobody I know voted for him!!!"
Good points and worth considering. I really hope we are not that much of a minority. We have a lot of work to do.
