I've written before that I think part of the problem that conservatives/Republicans face is that their mythology has become a bit too complex for mere mortals (people who don't listen to Limbaugh and read The Corner obsessively) to comprehend. They reference rogues' gallery of enemies and various "bad things" that most people have never heard of. Simply trying to navigate through the various wingnutty minefields while throwing out the appropriate red meat has become difficult to do, and the result is incomprehensible to most of the country.
