Couple of keys. The NRA has been VERY forgiving to Bisbee over CCW(he voted against, endorsed him with a B). The Chamber loves him as well(and he IS good on tax issues), and he is pro-life.
DeRossett leads in the money race. He got Ted Nugent's endorsement as well and that is huge since Nugent is big out in Jackson especially.
I expect the NRA to jump in here as well because of Schwarz's gun grabbing views.
Advantage IMO goes to Bisbee or DeRossett. I'd rather see DeRossett than Bisbee because of the CCW vote, but I'd take Bisbee over Schwarz. Then again, I'd vote for Granholm over Schwarz.
