Which state Republican party is the most extreme?

Somewhere in the Deep South.  An interesting counter one is which GOP is most moderate.  I would probably say Vermont, Massachusetts, and perhaps Maryland.  Maybe California, certainly Arnold Schwarznegger was quite moderate compared to much of the party but Pete Wilson was fairly right wing so not sure if they've swung rightward since.  Mind you the GOP is increasingly becoming an endangered species in California.
