When pressed on MSNBC's "Morning Joe" on whether he would vote "enthusiastically" for the former Massachusetts governor, Huntsman said, "Well, I think he [Romney] is the person who can get this economy going again."
The former Utah governor praised Romney's campaign message of job creation and economic revitalization.
Although Huntsman was critical of his fellow candidate during the primary, he endorsed Romney and called for party unity in a speech announcing the suspension of his campaign in January.

"We we're talking about that last night. I said 'you know if you're not on script and you get knocked out of an event like that — the parties are supposed to be big tent, you're supposed to bring in all ideas' and I said 'I thought for a minute about what they do in China if you're off-script … They knock you out. We shouldn't be doing that here. We should be accommodating all voices,'" said Huntsman.
