Mitt Romney and Rick Santorum may just have to learn to share. Based on the way the vote went in Tuesday night’s Michigan primary, the Republicans are likely to split on the state’s 30 delegates. The final delegate is still undecided because Michigan, Romney’s boyhood home state, awards its delegates on the basis of each candidate’s performance in the state’s 14 congressional districts. The winner does not take all. So while Romney’s camp was quick to crow over its narrow Michigan win, Team Santorum has come out to say that a closer look reveals that their candidate is really the one that deserves the laurels, with Santorum calling his Michigan performance “a huge win” at a Tennessee campaign stop Wednesday.
