Jimmy Carter calls Huntsman a 'very attractive' candidate

President Obama has already -- tongue in cheek -- given potential GOP presidential candidate Jon Huntsman his endorsement. Huntsman, a former Utah governor, served as Obama's ambassador to China.

And now comes news that former Democratic President Jimmy Carter finds him a "very attractive" candidate.

The Hill reports:

Carter, the one-term president to whom conservatives sometimes gleefully compare Obama, told CNN that Jon Huntsman, the former Republican governor of Utah who resigned last Saturday as Obama's top diplomat in China, might make for Obama's best GOP challenger.

Carter said that Huntsman is "very attractive to me personally," but also said that his "intention is to vote for the Democratic candidate."

This will be Huntsman's challenge if he runs for president: being portrayed as the left-most candidate in an increasingly right-leaning Republican Party.
