For this finale,Gov. Chris Christie will be back on the main stage, along with eight other GOP hopefuls.

Much was made of the fact Christie was kept away from the center court during the last outing by this group of hopefuls during the November debate.

Christie has seen a resurgence in recent weeks, particularly in New Hampshire which is a key state for his campaign.

Tonight's CNN Debate is the fifth of this primary season for the Republican field of candidates.
