Donald Trump has once again said that if Republican primary voters can't pick a candidate he believes will beat President Obama, he'll run for president himself.
The "Apprentice" host will moderate a Republican debate in Des Moines on Dec. 27, one week before the Iowa caucuses.
Newt Gingrich is the only potential candidate set to attend the debate, an event that has been derided by the campaigns of Ron Paul and Jon Huntsman.
The debate contributes to “an unwanted, circus-like atmosphere,’’ according to Paul, while Huntsman’s campaign called it “the presidential ‘Apprentice’ debate with Donald.’’
NBC figures show that voters in Iowa and New Hampshire would be less likely to support a candidate who gets Trump’s support by a 2-1 margin.
