According to the most recent survey by Middle Tennessee State University, Rick Santorum is leading the pack among Republican voters in the Volunteer State. 40 percent of voters say that they favor the former Pennsylvania senator, compared to the 19 percent who prefer Romney. Another 13 percent back former House Speaker Newt Gingrich, while Ron Paul takes 11 percent. Because Tennessee's 58 delegates are handed out proportionally, however, Santorum will have to win big in order to close his 80-delegate gap with Romney.
Of course, as we saw with Santorum's lead in Michigan, this advantage could disappear within the next week if Romney decides to contest the election with a barrage of negative advertisements. As it stands, however, the focus is on Ohio-by and large, the political world has determined that the Buckeye State is make-or-break for the former Massachusetts governor. Like Romney and his win in Arizona last night, Tennessee will matter a lot if Santorum wins Ohio, and recede to the background if he doesn't.
