GOP presidential candidate Mitt Romney, the Mormon former governor of Massachusetts who led the nation in government-based health reform, is already no favorite with the Tea Party-wing of the Republican electorate. He has now cemented that unpopularity by saying in public what he said in his book last year: that he stands behind the vast majority of the world's climate scientists who believe that the planet is warming and that that's a bad thing and that humans are no small part of the problem-- not that he's going to do anything about it, policy-wise.
