GOP candidates will debate just prior to the February 1 kick-off of the Iowa caucuses. Fox News will host and moderators will include Bret Baier, Megyn Kelly and Chris Wallace.

Prime-time debate candidates must place in the top six nationally in an average of five recent polls (released by Jan. 26), or in the top five in Iowa or New Hampshire polls. The “undercard” debate candidates must register at least 1 percent in any of the five most recent national polls recognized by Fox.
