Some thoughts.
Romney- Well, no matter where Romney placed tonight, his constituency in the MSM (until after he gets the nomination, anyway. See also John McCain) was going to declare it a victory for him. Really, though, he spent millions of dollars, had the whole of the GOP establishment behind him, had a huge organization, and he got a whole 8 votes more than a washed up ex-Senator who had the good fortune of being the last "not Romney" the base looked at. He got less of a percentage than he did in Iowa in 2008.
Santorum did well, and he's the "not Romney de jour for the moment. This just means that MSM hasn't gotten around to sliming him like they've slimed everyone else. He lacks the organization, but he might get a grassroots swell at this point. We'll see.
