OH isn't Rick's most important state on Super Tuesday. GA is the most important. If he can knock Newt out of the race, then he can finally go one on one with Romney. A OH win would be icing on the cake.
Maybe, though I doubt that Santorum will win GA. But OH is must-win, I think, for Romney.
No, it's more must win for Rick.
If Romney loses Ohio, one of the biggest swing states in the country, he's going to be right back where he was before winning Michigan last night. Only worse, since it will be the third time he has failed to leverage a major primary victory into uncontested front-runner status.
Romney may be back where he was perceptions-wise, but he'll still have a good delegate lead.
He will, but he'll be a long way from a majority, and March will be a tough month for him.
Even perceptions will be difficult, if he doesn't win other states. The threat, in terms of staying power, is Gingrich. He stays in and Santorum has a problem.
