A very large number of Freepers are not in line with President Bush or Senator McCain. Heck, the only GOP candidates I ever voted for in the primaries were President Reagan and Senator Goldwater. That doesn’t mean that they and I will not be voting for Palin/McCain in the election.
I'm certainly not voting for McCain out of enthusiasm for his policies; I'm voting for McCain as a way of stopping Obama. It's kind of like using a parachute as opposed to leaping out of the plane without--either way, we're heading for the same place.
