John Huntsman is expected to call it quits and endorse Mitt Romney.
Lacking the support to get his campaign moving, Huntsman recognizes that he should call it quits. He is also reported as saying that he wants to endorse the candidate that has the best chance at beating Obama. That person is Mitt Romney.
Also, Rick Perry is reported to make an announcement come Saturday on continuing his efforts. Reports say that if he fails to come in first or second in South Carolina, he will be pulling out of the race. If reports are true, it is still unsure who would get a bump from his supporters and who would get his endorsement.
