Huntsman says Haley endorsement 'not crucial at all'

Earlier on Thursday during an interview on the Laura Ingraham show, Haley said she would not endorse Huntsman's campaign.

"Naturally, I am going to go with someone that philosophically I agree with, and Jon Huntsman is not it," Haley said.

Haley's is a coveted endorsement for Republican presidential contenders given that she has promised to announce her candidate ahead of South Carolina's primary. The primary has been especially important to GOP presidential hopefuls since 1980 as the primary winner has consistently gone on to win the Republican nomination.

Huntsman noted that his campaign has won the support of South Carolina's attorney general, Alan Wilson (R).

 "We just got the endorsement of the attorney general of South Carolina — the first constitutional officer in the state to come out and endorse anybody," Huntsman added. "We have a lot of support in South Carolina, I like our chances there."
