Candidates must meet one of the following criteria:
1) Place among the top five candidates ranked according to the popular vote in the New Hampshire Republican primary on Feb. 9, 2016;
2) have placed among the top three candidates ranked according to the popular vote in the Iowa Republican caucuses on Feb. 2, 2016;
3) place among the top five candidates in an average of national and South Carolina Republican presidential polls conducted over a four-week period starting on Jan. 15, 2016 and recognized by CBS News; and receive a minimum of 3 percent in the Iowa, New Hampshire results or the South Carolina or national polls.

So this means Trump, Cruz, and Rubio are definitely in. Kasich and Bush are probably in. Ben Carson might be in if he doesn't collapse in South Carolina after tonight. But Christie could very well be out? Fiorina and Gilmore, screwed once again.
If I correctly undestand, they will include candidates who got >3% in NH. So I think Christie, Fiorina and Carson are pretty safe.
