One word for that mentality -- DUMB!
RINOs do far more damage because Republicans won't stop liberal legislation pushed for by a RINO.
And, let's not forget the damage done in Congress. The party in the White House almost always loses seats in Congress. Just think how much worse that trend will be with a social liberal driving Southern conservatives and Catholics back to the Democratic party.
At least with Hillary in office, Republicans will start gaining seats in Congress. And, the Republicans are far more likely to oppose liberal legislation from her than from Giuliani.
