Friday afternoon, The Heartland Institute announced that they would stop running this billboard over the Eisenhower Expressway. That’s Ted Kaczynski, who worried about man-made climate change in his manifesto before he rendered the phenomenon nonexistent by mailing bombs to scientists. The ad was to be part of a series featuring public figures who expressed belief in global warming, including Fidel Castro, Osama Bin Laden and Charles Manson. It was to be classy. Then a bunch of debate-team types called in and forced them to cancel it, which—as Heartland’s press release explains—was what they wanted all along. “This provocative billboard was always intended to be an experiment,” Heartland President Joseph Bast said through his press agent. “And after just 24 hours the results are in: It got people’s attention.”
