Obviously the NBC online poll wont count to the CNN average but if live phone polls come out with the same results then Fiorina would certainly make her way into the top 10, likely knocking out Christie (if he continues to underperform Kasich).
This brings up an interesting question...would Christie (or anyone from the Fox top 10) attend the CNN JV debate? There is a certain humiliation to being relegated down from the primetime debate. According to Kasich's campaign manager, if Kasich didn't make the top 10 for the FOX debate he planned to spend the day in New Hampshire and skip the debate. Unsure if that means he would do the same for the CNN debate.
Fiorina showed the advantage for a Christie.
If he does well enough in the JV debate, it can resuscitate his campaign. His competition isn't as talented on-camera (I have not heard any claim that Rick Perry did better than any of the top ten), he'll have more time on camera, and the ratings are still going to be decent (The JV debate had better ratings than any of the 2012 primary debates.)
