All 4 candidates will remain in the race.
Santorum wins Obama's Momma's homestate (Kansas) as well as AL and MS.
HI votes for Romney or Gingrich (lol ... not).
Interesting. That's what I think will happen, although I think depending on what happens in Georgia and Tennessee, Alabama and Mississippi could go for Gingrich, or at least be competitive between the two. Mitt Romney, though, really needs to win a southern state to prove he's electable just about anywhere in the country, not just the west and parts of the midwest.
