I read that the Repugs are now polling for Huck because they really haven't been excited by RG and Willard who sort of created their own momentum in spite of their obvious faults as seen by the "religious" dolts.
iow, the Repugs and red-staters, and esp the "Christian" supremacist and s who apply a "religious test" as their primary criterion for office (dubya passed that test and led the s and country straight to but, "he's a "Christian" ") are getting behind Huck by default, there's nobody else, to escape the faults of RG and Willard.
