"before he really screws up the system" - The GOP is already screwed up; it will take several election cycles to clean out the teabaggers...In '10 the GOP welcomed/encouraged the extremists but it backfired and attracted extremist candidates...In normal times Herman Cain, Michele Bachmann and Rick Perry would be laughed off the nat'l stage but these are not normal times in the GOP as the extremists take turns winning polls in neocon states.
Mitt Romney is not an extremist; he just has no core values.
