Jon Huntsman may be lagging in the polls, but he certainly leads the Republican presidential field in daughters willing to make viral videos promoting his campaign.

The three Huntsman girls latest effort  is a parody of the the Justin Timberlake song 'SexyBack' (without the dirty parts, of course) called 'Huntsman's Back.' And we can't decide if it's awesome...or excruciating. Or possibly both. 

The quick little ditty makes the somewhat dubious claim that their pop, the former governor of Utah,  is 'right on track' for the GOP nomination and dismisses his rivals Herman Cain, Mitt Romney and Newt Gingrich as a "circus act."
