Rick Perry barely qualified for this debate and it appears that CNN went out of its way to make sure he met the criteria. More on this from Politico:

CNN's Sam Feist calls to say that contrary to the report by Talking Points Memo, Rick Perry has met the criteria for the debate on January 19. Per CNN criteria, a candidate qualifies for the debate if he averages 7 percent in three national polls in 2012. Feist says that Perry averages at least 7 percent based on a Gallup poll from January 3, a CBS poll from January 9, and a Reuters/Ipsos poll from January 10.

In the Gallup poll published January 3, Perry received 7 percent.

In the CBS poll published January 9, Perry received 6 percent AND 7 percent.*

In the Reuters/Ipsos poll published January 10, Perry received 7 percent.

*The source for all the confusion: When CBS published the results of its poll on January 9, it listed Rick Perry at 6 percent. However, the full release shows that Perry received 6 percent when those surveyed had an option to choose "Someone Else," and received 7 percent when those surveyed did not have that option. Because Perry received 7 percent in the latter poll, he qualifies for the CNN debate in South Carolina… by the skin of his teeth.

So Perry just got his toe in the door on this one which still leaves him in OK standing. The fact that he nearly missed the cutoff doesn't bode well for him.
