Why would a candidate with Ron Paul's approval ratings attack a candidate with John Huntsman's approval ratings?
Rule #1 of ANY advertising or political campaign: NEVER attack an opponent who holds a lower position than yourself.
Simple understanding: This is Blowback from the stupid TWITter attack on Huntsman from the mental incompetent on Ron Paul's campaign staff.
Rule #1 from Dad: "Sit down! Shut up! Enjoy the ride!"
