So far, Romney’s reviews from the right are not positive. His views about climate change in particular put him at odds with many in his party’s base.

“Bye-bye, nomination,” Rush Limbaugh said Tuesday on his radio talk show after playing a clip of Romney’s climate remark. “Another one down. We’re in the midst here of discovering that this is all a hoax. The last year has established that the whole premise of man-made global warming is a hoax, and we still have presidential candidates that want to buy into it.”

Then came the Club for Growth, which issued a white paper criticizing Romney. “Governor Romney’s regulatory record as governor contains some flaws,” the report said, “including a significant one — his support of ‘global warming’ policies.”
