A survey of self-described Republicans by Research 2000:

Bruce Bartlett on "why I am not a Republican":

I can only conclude from this new poll of 2003 self-identified Republicans nationwide that between 20% and 50% of the party is either insane or mind-numbingly stupid.

Ezra Klein:

DailyKos.com contracted the pollster Research 2000 to pull together a random survey of self-identified Republicans and test the prevalence of some of the stranger ideas floating around.

The answer, sadly, is that these ideas are very prevalent.
