I don't think it's a lose-lose if Romney sweeps on Tuesday. Santorum's support will fall, but I don't think Gingrich will have another rise. A Gingrich rise would have required a strong debate performance the other night, and while it was good, it wasn't good enough. With a Michigan victory, you'll see Romney keep all of the supporters he has and pick up some more; Santorum will go down a bit and Gingrich will go up a bit. It's still a split.
Now, if Santorum won, it'd help him, and even more would be leaving Gingrich's camp for Santorum. I definitely think there's a "win" situation for Romney, though.
I agree with this assessment. While I think Gingrich prevented himself from becoming flavor of the month again with his doubling-down on the Moon Base stuff, he should still win Georgia. However, who knows which way Tennessee and Oklahoma will go. It's possible Santorum could take a hit after losing Michigan (not guaranteed - Democrats may push Santorum over-the-top in Michigan), but still manage to win those two states on Super Tuesday.
In all likelihood, the race is going to continue beyond Super Tuesday.
