If Gingrich does pursue this march—and there are two debates this weekend in New Hampshire in which Gingrich can be a suicide bomber—Gingrich will be reaching the peak of his three-decades-long career as a Republican demolition man. And now his target will be the candidate the GOP establishment believes possesses the best chance of unseating President Barack Obama…

[H]aving been on the receiving end of Newt-like treatment, Gingrich is not going to quietly skulk back to his Newt Inc. empire and continue to cash in. First, it seems, he must crush Romney. Which is not such a hard task. At the upcoming debates, Gingrich will have plenty of ammo—all those flip-flops and what-nots—to blast Romney to smithereens. If Gingrich goes scorched earth, he can provide much material for Democratic anti-Romney ads and will obviously tick off the Republican Party poohbahs who have already decided that Romney is the only credible candidate in this sorry lot.

It will be as if a time bomb with a very long fuse has finally detonated.
