Rick Santorum is dropping out of the race for the Republican nomination.
The polls in Pennsylvania must have been brutal.
So the last viable non-Romney standing has been defeated—and that leaves Romney, standing. (Ron Paul remains standing as well, but he was never really the non-Romney alternative, he was always a phenomenon unto himself. And Newt Gingrich is kind of lying down.)
I think Romney has shown us a couple of things about his personality. One is that he’s not afraid of a fight, or even fighting dirty if need be. Another is that he’s very organized. A third is that he isn’t easily rattled or disheartened. All those things will come in handy for the main event.
