The conservative Heartland Institute put up this outdoor board and took it down the same day after public protests began.  Apparently, it was designed to be the kickoff for a campaign that would also feature Charles Manson, Osama Bin Laden and Fidel Castro, because as the institute noted, "what these murderers and madmen have said differs very little from what spokespersons for the United Nations, journalists for the 'mainstream media' and liberal politicians say about global warming."  http://tinyurl.com/d5gpt2c
 
Other shocking agreements between liberals and these murderers and madmen, uncovered by the Heartland Institute:

  * The Earth revolves around the sun
  * 2 + 2 = 4
  * Water is wet
