Our chance to force Romney out happened back about this time last year when the best we could do was muster candidates like Cain, Perry and Bachmann who all disappointed us. If we can't fill a GOP debate stage with better candidates, why is it Romney's fault that he is now running ahead of candidates we were not supporting back in those first five or six debates? He is ahead because the rest of the pack have their own issues.
You're wishing for a do-over. Good luck with that
