When you have limited resources as the Gingrich campaign is currently experiencing, you have to use them where they will count the most.

For Gingrich, who won only his home state of Georgia on Super Tuesday, and finished a disappointing third in other states, it appears that next Tuesday's primaries in Alabama and Mississippi may be his last stand. The candidate has cancelled several appearances in Kansas prior to the Saturday caucuses in that state, to throw everything he has left into trying to win two key deep south states and keep the argument alive that he is the conservative alternative to Mitt Romney.

Wall Street Journal:

On Tuesday night, Newt Gingrich promised to continue his campaign to in Alabama, Mississippi and Kansas.

By Wednesday morning, his struggling operation decided to shoot for two-out-of-three.

In the latest sign the former House speaker's White House bid is on the ropes, it has canceled all travel to Kansas before Saturday's GOP caucuses there and its spokesman, R.C. Hammond, said Alabama and Mississippi, which vote March 13, are must-wins if Mr. Gingrich is to remain credible.

Consider this exchange between Washington Wire and Mr. Hammond.

Q: Newt said he had to win Georgia to remain a credible candidate. Does he have to win Alabama and Mississippi to remain a credible candidate?

A: Yes.

Q: He has to win?

A: Yes.

Mr. Hammond would not say if Mr. Gingrich would drop out if he loses either of those states.

Gingrich may not have a choice about staying in if he can't win at least one of those two southern primaries and finish second ahead of Romney if he doesn't. The delegate math is already heavily against him (he would have to win 70% of the remaining delegates to reach 1144). His money is short, his organization almost non-existent. These are deficiencies only victory can fix.

He has a realistic shot in both states. He is a Son of the South and this plays well among many southerners. Whether it is enough we'll just have to see.
