Jon Huntsman, who makes calls for civility in political discourse a key part of his stump speech, doesn’t intend to do much in the way of naming names on the campaign trail. From Politico:

“He’s not one to tear anyone down by name, whether that person is Gov. Tim Pawlenty, Gov. Mitt Romney or President Barack Obama,” said Matt David, likely to be Huntsman’s communications director. “I think he’ll make it clear where he disagrees when it comes to policy and where he wants to take this country, but for him this is a campaign based on substance and not names.” …
A Huntsman aide suggested a high road approach wouldn’t stop them from drawing distinctions.
“The campaign will do everything in our power to lay out that choice for voters,” said the aide. “Part of that choice is showing where various candidates are on the issues. We will do that in the Huntsman campaign.”
