Debate fatigue is setting in with both the canidates and the audience - as the next debate after this one was cancelled by CNN when all of the Republican Presidential candidates except for Newt Gingrich backed out. Whether the candidates will agree to more debates in the future is unknown.
The debate, taking place in Arizona, will start at 8 PM Eastern time, with John King moderating.
Since the last debate in Florida, Gingrich has fallen off significantly, with the primary battle narrowing to be between Mitt Romney and Rick Santorum. Even though the debate is in Arizona, much of the focus of this debate will be towards Michigan where Romney and Santorum are neck and neck in the polls.
Michigan and Arizona both hold their primaries on Feb. 28th.
