They’re already voting or decided and so it is the ones who are less attentive to politics and could easily be turned off and might not even come out after they see the negative ads,” said Mac McCorkle, professor of the Practice at Duke’s Sanford School of Public Policy. So, a lot of it is looking for that knock-out punch that given the torrent of ads might be hard for people to see,” said McCorkle who has worked for state and federal candidates in North Carolina as well as 28 other states. “The party lines are so far removed from one another I would be hard pressed to say anyone is going to see some political ad and then think oh my goodness now I want to vote for someone on the other side of the political aisle,” Tripodi said.
