GOP frontrunner Donald Trump, Sen. Ted Cruz (R-TX), Sen. Marco Rubio (R-FL), Dr. Ben Carson, Gov. Chris Christie and former Florida Gov. Jeb Bush are most likely the six GOP presidential candidates that will appear on the main debate stage at the Fox Business GOP primary debate in South Carolina this Thursday, according to Politico. After the recent NBC News Wall Street Journal/Marist poll, Politico calculated the candidates not likely to make the debate stage this time around are: Sen. Rand Paul (R-KY), Ohio Gov. John Kasich, Carly Florina, former Arkansas Gov. Mike Huckabee and former Pennsylvania Sen. Rick Santorum.
