ANDREA SEABROOK, host:
And now to Audie Cornish, who's also at South Carolina at the Convention Center in downtown Columbia, where Mike Huckabee has his headquarters.
Audie, what's the mood there?
AUDIE CORNISH: I think the mood is just as cautious as it is over at McCain's place. Essentially, the campaign managers here are repeatedly bringing up the bad weather, I think maybe downplaying expectations because some of worst weather was in the areas of the state that where the most Republican, the most conservative and the most evangelical.
SEABROOK: Audie, what did you hear from voters this week? I know you spoke to many of them.
CORNISH: Well, there's definitely a divide in terms of you have your evangelical vote, but that's not a monolithic vote. There are folks behind the sort of Bob Jones University people, and fundamentalists who back Mitt Romney. You have the Southern Baptists of there's more than half a million in the state. And they obviously are tends to support a Baptist like Mike Huckabee. So it wasn't obvious which way these votes would go, even though it would seem that Huckabee obviously has a natural constituency here.
SEABROOK: Now, do we have any word that Mike Huckabee will be speaking at all tonight?
CORNISH: He will be speaking, but we don't know when. And I think that's because it's so close right now. We're not hearing a lot from the campaign about exit polls. They're not really wanting to get to details to talk about it.
SEABROOK: It's a nail-biter. NPR's Audie Cornish in Columbia, South Carolina. Thanks very much, Audie.
CORNISH: Thank you.
