Honestly, Gingrich needs to go hard after Santorum in the debate on Wednesday, rather than focus on Romney, which he'll probably try to do. The only way Gingrich can still win is if he completely deteriorates Santorum enough to once again by the "Anti-Romney" choice. He's not going to be able to make this a two-way race between himself and Santorum, try as he might.
No, Romney is still the frontrunner and still has the clearest path t the nomination without a brokered convention. If Santorum gains steam in delegate collection, it's more likely we go to a brokered convention and Gingrich could get something out of it.
