Columbia -- The two major candidates in the governor's race, Republican Nikki Haley and Democrat Vincent Sheheen, have agreed to face off in a third debate Oct. 19 in Spartanburg.

Sheheen and Haley have recently disagreed over the appropriate number of debates and the format. Haley's campaign has accepted four debate invitations from TV stations while Sheheen has pushed for a series of Lincoln-Douglas-style debates across the state.

Last month, both campaigns agreed to two back-to-back debates in late October -- one hosted by ETV to air statewide Oct. 25 and another hosted by Francis Marion and Coastal Carolina universities in conjunction with Florence and Myrtle Beach news outlets Oct. 26.

"We had initially proposed five debates and we liked the (Lincoln-Douglas) format because it's more in depth and the best way for the candidates to inform voters on their platforms," said Kristin Cobb, Sheheen's spokeswoman. "We'll continue to look for other opportunities to debate."

Haley, when asked by a reporter from The State about the debate schedule Wednesday, refused to answer.

Her spokesman, Rob Godfrey, said four debates "is a robust debate schedule."

Sheheen spent Wednesday in Columbia campaigning; Haley's received an endorsement from the S.C. chapter of the National Federation of Independent Businesses.
