I'd back Brad Smith over Schwarz and Bisbee(voted against CCW), that's for sure.
Ideally, I guess DeRossett is the best of the bunch, but I'm worried he won't break out of the pack (or at worst, take votes away from Smith). In that article William linked, Ed Sarpolus seemed to be suggesting right-to-lifers get behind Bisbee and help "save his career", but Bisbee, as you said, doesn't seem like a great choice (and were Schwarz not in the running, Bisbee would be the RINO of the bunch).
