Cain is conservative. So are Bachmann and Santorum. What are you talking about?
Conservatives have the ability to serve all three factions of Conservatism. None of the above are able to function as CiC- none have military or foreign policy experience... And that's just for starters...
I am not a Military/Foreign Policy type - But I do understand that I shouldn't expect these conservatives to take a back seat... nor should fiscal/libertarians or the Christian Right. And these are perilous times abroad as well as at home - To loft a candidate with no experience in this area is not just poor judgement, it is downright dangerous.
