Today's Jon Stewart Moment

Courtesy of Andrew Sullivan, two Romney quotes within five months of each other:

"I believe based on what I read that the world is getting warmer. And number two, I believe that humans contribute to that. I don’t know how much our contribution is to that, because I know that there have been periods of greater heat and warmth in the past but I believe we contribute to that. And so I think it’s important for us to reduce our emissions of pollutants and greenhouse gases that may well be significant contributors to the climate change and the global warming that you’re seeing," -- June 3, 2011

"My view is that we don’t know what’s causing climate change on this planet. And the idea of spending trillions and trillions of dollars to try to reduce CO2 emissions is not the right course for us." -- October 27, 2011

Cue Stewart's deadpan look into the camera, followed by an excited: "I'm running for office, for Pete's sake, I can't be seen believing in climate change!"
