One can only hope so. The more important question is which of all the other clowns on the current list will be nominated.
I can't think of a single one who would be anything more than the "lesser of two evils" type candidates they have put up in the past.
I live for the day I can actually vote FOR someone.
A candidate meeting your criteria will be a ways off.
I can think of several that I would like to see run that I think could win the GOP nod, but probably won't. The best of the bunch would be Jeff Sessions. James Inhofe and Sam Brownback are also good. In the house, Mike Pence and JD Heyworth come to mind.
And any of these guys would take out McCain or Rudy, IMO. There will definitely be a conservative in the race and its better for him not to announce yet anyway.
