NPR just aired an interview with the chair of the Republican Party in NC and she says the ad will run. When asked if she’d pull the ad if McCain asked her personally to do so, she said nope, the people of NC need to hear the message.
This is a tried-and-true campaign tactic. The fact that the TV folks rose to the bait means one of two things. Either they are naive suckers, or they are actively participating in the bashing.
The ruse works like this. A very negative ad is “leaked” to TV stations and web sites. The candidate who gains denounces it, and he calls for it to be pulled. That makes it news, so the TV folks show the ad as news through several cycles (when the candidate condemns it, when the ad’s parent defends it, and when the ad is finally pulled.) For three or four days, voters are told the slam piece is important. Now, here’s the beauty part. The ad is all over the airwaves, then it’s pulled, so nobody had to pay a dime for all that exposure! The candidate was first to condemn it, so he’s still squeaky clean; no mud on his hands.
It has been played masterfully in the last few presidential cycles.
