Florida won't be remember so much for Romney's decisive victory, but how that victory was achieved.
Romney's SuperPAC assault has enraged Gingrich and the real war is about to begin. Gingrich is a nasty, unethical, vindictive ego-maniac -- by previous accounts from former staffers, he's a "sociopath" and he won't quit until he destroys Romney. It doesn't even matter to him whether he wins this thing, it's personal now and Gingrich is out for blood.
Get ready because in a month or two Florida is going to seem like ancient history. It's going to be a long fight between these two, and it hasn't even begun to get ugly.
