GOP sources said they expect the ad to be taken down in light of new reports that it was filmed in Philadelphia, and that a casting call was looking for characters with a “‘hicky’ blue collar look,” according to a report from Politico.

The hasty move to pull the ad is a sign Republicans are seriously concerned that the revelations could threaten John Raese’s (R) surging candidacy in the Mountain State.

“No one at the NRSC, or associated with the NRSC, had anything to do with the language used in this casting call,” said NRSC spokesman Brian Walsh. “We do not support it, and suffice to say, we would encourage our contractors to never work with this outside agency again.”
