Former Utah Gov. Jon Huntsman
Huntsman backed Romney when he pulled out of the race in January, but Romney was notably absent when the former Utah governor gave him his blessing.
Huntsman raised some eyebrows a month later when — despite his endorsement for Romney — he said the GOP lacked big ideas and called for a third party to fill the void.
“I think we're going to have problems politically until we get some sort of third-party movement or some alternative voice out there that can put forward new ideas,” Huntsman said on MSNBC.
Huntsman had millions of dollars of debt when he exited the race, and finance records show he loaned his defunct campaign $1.5 million in the first quarter of 2012 to help close the gap. He still owes more than $1 million.
