"It's possible that the parallel universe created by the Right has gotten so complex that it's become exclusionary. I've tried to get a handle on this before, though I don't think I've quite managed to pin it down yet. I've mentioned before that it seems that members of the movement Right demand that their candidates buy into the Entire Package of Wingnuttia. This isn't simply political purism, it's about validating a worldview. There are all these articles of faith in wingnuttia which have been given to them by the wingnut noise machine, and failure to embrace them all is a signal that you aren't really part of the club."
