They shouldn't. At this point, I could vote for any of the Republicans on the ballot EXCEPT Rudy. I
don't have a religious test - I consider both Mitt and Fred to be members of cults, but I'm supporting Fred in the primaries at this point, and would be willing to support Mitt if he turns out to be the nominee.
I'm not a single issue guy, either. I don't like CFR, but I'll tap McCain if he's on the ballot next November. Huckabee made a fool of himself on the outside smoking ban, so I don't back him in the primary, even though he is one of the strongest supporters of Christian views.
So perhaps it is you gun grabbing pro-abortionists that are narrow minded.
Uhh, I'm pro-life and pro-gun. That might screw up your narrative, but sorry. Facts are a b**tch.
