NC-PPP: Romney ahead, but Santorum winning if Gingrich drops out

And, Romney's vote share goes up with a Gingrich exit.  Whether Gingrich is a spoiler or is helping block Romney, depends on how a state's system for awarding delegates. Though in terms of headlines and momentum, he hurts Santroum.

In North Carolina, certainly, Romney does better vs. ABR with Gingrich out of the race, delegate-wise.  Though a Romney win in NC (with fewer delegates) may give him more "momentum," if that means anything in this race anymore.
