When a town hall attendee asked Rick Perry about groundwater pollution from hydrofracking, he sneered at the idea, saying that it would have had widespread press coverage if it were true:
Perry: I am truly offended that the American public would be hoodwinked by stories that do not scientifically hold up. If that was true, it would be on the front page of every newspaper. It would be on ABC, NBC, CBS, Fox News. Everybody would be running that story.
Well, whaddya know? He's right.
