Bush has extra incentive to attack Christie immediately and try and knock him from main debate.
Well if you look at the last national poll and the last 3 NH polls, Christie is ahead of Bush. So if anyone is pushing anyone out it the other way around. But for Bush to get pushed entirely out it will take Kasich, Paul or Fiorina to make some gains.
Yeah, I retract that. Bush will attack Christie and Rubio anyway because he's trying to beat them in New Hampshire but seems unlikely to keep him out of this debate.
