Bravo: "Sensenbrenner plans to deliver his speech now that the campaign has been canceled"

Again, to me, there is absolutely no question that the Heartland folks are fighting in good faith on the side of truth in the global warming wars. Instantly and permanently "throwing your allies under the bus" if they ever make a mistake isn't a winning strategy.  In this case, that would be doing exactly what Peter Gleick, Chris Mooney, Al Gore, and Michael Mann hope that you do.
Group provokes reaction with billboard doubting global warming - chicagotribune.com

Among the critics of the Unabomber billboard was U.S. Rep. Jim Sensenbrenner, R-Wis., who threatened to cancel his speech at the institute’s climate change conference later this month in Chicago if the group did not pull the ad.
Sensenbrenner plans to deliver his speech now that the campaign has been canceled, and “wants to get back to focusing on the issues because we can win this debate without the name calling,” his spokeswoman, Amanda Infield, said in an email.
Sensenbrenner opposed the ad because “this type of name calling did more to distract from the issues at hand than advance a positive dialogue,” Infield said.
In announcing the Unabomber billboard on Thursday, Bast said in a statement that “the leaders of the global warming movement have one thing in common: They are willing to use force and fraud to advance their fringe theory.”
