Maybe MB thinks Dole, McCain and Romney are those conservatives driving moderates like him away from the Party.
Actually, I think that MB is a Libertarian and wants them to control the Party instead of the moderates and kick all conservatives out, which has almost been the case.
The GOP has not been winning because you can’t outbid folks who are willing to spend every cent you have. We’ve hit a tipping point where the folks voting for “free stuff” will out vote the folks voting for “leave me, my family, and my stuff alone.”
