(CNN) - Bob Jones III, an influential evangelical leader and chancellor of the fundamentalist Christian Bob Jones University, said in an interview set to air Sunday that the race for the 2012 GOP nomination is by no means wrapped up.
"I don't think this thing has been anywhere close to being nailed down yet, and probably not until the voter actually goes into the booth and casts his vote. Everything is up for grabs, in my estimation," Jones told CNN Chief Political Correspondent Candy Crowley.
The full interview will air Sunday at 9 a.m. ET.
Jones endorsed Mitt Romney in 2008 – a surprise move given the skeptical stance many conservative Christians bear toward Mormons. Jones said an endorsement this time around hadn't come because Romney hasn't asked.
"Well, in 2008, he was very solicitous of the evangelical vote," Jones said. "If he is that today, I am unaware of it. I certainly have had no contact with him, and so I don't know whether he feels he needs it or wants it, whether he considers it a plus or a minus for him. That was a different dynamic then."
