I would add that the only truly “bad” candidates at this point are Romney, Paul, and Huntsman. I want Huntsman to stay in it though, he’s bleeding off one or two points from Romney. As for Paul, his people are not Republicans. They are just tired of being left out. If they weren’t voting for Paul in the primaries, they’d be sitting at home posting on libertarian forums.
It looks like you do have to be wild-ass worldwide war supporter to be considered a conservative these days.
