Remember the days when Mitt Romney was considered a moderate Republican, a rational guy who didn’t follow the standard GOP anti-science line? A guy who accepted the science of both evolution and global warming?

Well, those days are gone: Romney says would not put limits on emissions.

(Reuters) - Presidential candidate Mitt Romney, in danger of losing his 2012 Republican primary front-runner status, on Wednesday he would not place restrictions on carbon emissions if elected.

Romney, the former Massachusetts governor, also said he does not know if human activity is the primary cause of climate change and does not favor spending heavily on climate solutions.

Asked about global warming at a town hall meeting in Lebanon, New Hampshire, Romney said he believed the world is getting hotter and humans contribute in some way to the change — but could not judge to what extent.

“Do I think the world’s getting hotter? Yeah, I don’t know that but I think that it is,” he said. “I don’t know if it’s mostly caused by humans.”

“What I’m not willing to do is spend trillions of dollars on something I don’t know the answer to.”

At this rate, it won’t be long until Romney starts praising “intelligent design.”
