Jon Huntsman may be trailing in every poll among Republican presidential aspirants, but he's way ahead in the pop-culture primary.
Huntsman, the former Utah governor and ambassador to China, will be appearing on "The Late Show With David Letterman" next Wednesday, according to The State Column.
Huntsman has made notable, and comical, appearances on both "The Colbert Report" (where he suggested Colbert as a running mate) and "Saturday Night Live" (where he solicited votes from Seth Meyers' New Hampshire parents).
