The Jeb Bush campaign and supporting Super-PACs are turning out to be possibly the most inefficient TV marketers ever when it comes to presidential campaigns. Bush sits at 3% in the polls, though not completely out of the race just yet. Though $17 million has been spent in New Hampshire, he’s still in single digits there. Bush and his allies have spent $9 million in Iowa, where the only high number he gets is in unfavorability ratings.
