No, PLEASE do not "just stay home". There WILL be other, more conservative candidates running for Prez in '08...chances are, tho, that they won't be in the GOP.
The candidates who have a much more principled stance against big government & US sovereignty will be found in the Constitution, Libertarian, & Independent American parties.
The GOP is no longer a safe haven for true conservatives anymore...don't be afraid to LOOK ELSEWHERE!
