They don't call it "Super Tuesday" for nothing. Ten states hold primary elections, and results can make or break a candidate who has made it this far. Even when the results aren't all that "super" for any one candidate, the contest can be a defining moment for the candidate who's still standing when the dust settles.
That's the case for Mitt Romney. Romney eked out a victory over Rick Santorum in the "must-win" Ohio primary , as well as four other states — including two states where his closest rivals weren't even on the ballot. Santorum pulled off victories in Tennessee, Oklahoma, and North Dakota, while Newt Gingrich won Georgia. So, Romney is not defined by a string of game-changing Super Tuesday victories, so much as what he had to do to win even as much as he did.
At this point, it no longer matters whether Romney's positions on the issues are based on what he genuinely believes, or whether he adopted them out a need to win his party's nomination. They're his how. He has no choice but to own them. Conservatives will hold Romney to them for the rest of the primary. They will keep him from straying too far from them in general election, and will demand that President Romney act on them.
As Mitt Romney positioned himself to win a primary contest that should have been over by know, he adopted or reiterated eight positions that hold devastating consequences for Americans struggling through this recession.
As I said above, whether these positions are based in genuine ideological conviction on Romney's part, or simply a desire to win his party's nomination, he owns them now. He has no choice but to own them, as he has to answer to a right wing that owns the Republican party. Ann Coulter  wasn't boasting when she told an audience at CPAC "We won! Folks, we won. There are no Rockefeller Republicans anymore! Conservatives won that fight." She was stating a simple truth; the same truth that defines and informs Romney's quest to win his party's presidential nomination.
Despite not scoring a decisive sweep on Super Tuesday, Romney is still inching towards the Republican nomination. Conservatives are still inching towards Romney, and realizing that even though they're not convinced that Romney is a "real" conservative, getting behind his nomination and supporting him in the general election increases their power in the party and over Romney himself. After all, he can't hope to win without their support. Jonah Goldberg sums it up, making a case for Romney by writing "A president who owes you is better than one who owns you."
If Mitt Romney wins his party's nomination and goes on to win the presidential race, he will owe a debt to conservatives that they will not let him forget. And they, in turn, will own him for as long as he is — an wants to remain — president. Positioning himself farther and farther to the right is the price Romney will pay if he wants to win. The positions he adopts in order to win reflect what we all lose if Romney — and right-wing Republicans — win in November.
