Republicans running for President are preparing in South Carolina for tonight's debate.

FOX's Rachel Sutherland reports from Charleston:

The stage is set here at the North Charleston Coliseum for the FOX Business Network debates. It's lighted in red and blue with seven podiums at the ready...

Front and center, will be Donald Trump, who's still calling on Ted Cruz to go to court prove he's eligible to run:

(Trump) "Ask the court for a ruling and then you can run, but you know you have to be careful."

Cruz, born in Canada of a U.S. citizen mother, is resisting Trump's calls. Three candidates: Mike Huckabee, Rick Santorum, and Carly Fiorina, qualified for the undercard. Rand Paul also did, but will not participate in that debate.
