I read somewhere that in Southern California in Orange county, the heart of the republican belt, only 40% of normal republicans voted.
I'd believe that. Most of us here are broken glass republicans, even if we have serious disagrements and no way are we going to sit on our hands much less vote for a rat but there's also a large population out there where politics aren't that big of a deal and, experiencing mild to moderate disgust said to heck with it.
