Mitt Romney asks for correction of climate quote - Darren Samuelsohn - POLITICO.com

How much is the Mitt Romney campaign sweating the candidate's stance on global warming?

This much: Late Monday, after enduring a blog-inflamed kerfuffle over the GOP presidential contender's view on EPA climate regulations, the campaign reached out to POLITICO to ask for a change in a Romney quote — an "of" to an "and" — that had been published several times since early June without objection.

Romney campaign officials said the corrected quote — distinguishing between “greenhouse gases” and “pollutants” — represents an "important distinction" in his views on climate change and EPA regulation.

“Gov. Romney does not think greenhouse gases are pollutants within the meaning of the Clean Air Act, and he does not believe that the EPA should be regulating them,” said Romney spokeswoman Andrea Saul. “CO2 is a naturally occurring gas. Humans emit it every time they exhale.”
