As I pointed out about that USA Today poll, even after all the "dirt" on Rudy comes out about his "horrific" views on gays and abortion, 55% of the GOP voters are still well disposed to him, and not bothered a wit about it as to his candidacy, and another 25% are still willing to at least consider him as a nominee. Only 20% freak out. Those that self identify as GOP must be a cohort that has now been taken over by "liberals."
That's the problem, 55% solid, 25% maybe and 20% no chance equals a loss.
