The GOP has little desire to control government taxes and spending, it benefits them and their controllers so much.
They can't do that now, not after solidly identifying with the Romney campaign -- the RNC and the Romney campaign are a single, continuous tissue of issue-manipulators playing a very short hand, limited by their perception that the Left has "won" every single argument on the table for the last 80 years. If they lose, that will not be the last of their resources, but it will be the last of their credibility -- which is already amazingly low.
Pottery Barn Rule now in effect for Rove and the rest of the Romney-pushers.
