In a short time, Alabama and Mississippi primary results will start being reported. My prediction is that both states will be wins for Gingrich and both states will be close. Mississippi should be an easier win for Gingrich, he should take the state by a couple of percent. That's close, but Alabama is likely to be as close as a few hundred votes. Romney could even surprise for first place.
Then again, that very threat could sway a few Santorum supporters to vote for Gingrich instead to prevent a momentum builder for Romney in a southern state. If Gingrich doesn't win in both states he's done, despite his intention to stay in. Tonight should be interesting.
