Former Vice President Dick Cheney has to be smiling. With one exception, none of the Republicans running for the Senate  including the 20 or so with a serious chance of winning  accept the scientific consensus that humans are largely responsible for global warming.

The candidates are not simply rejecting solutions, like putting a price on carbon, though these, too, are demonized. They are re-running the strategy of denial perfected by Mr. Cheney a decade ago, repudiating years of peer-reviewed findings about global warming and creating an alternative reality in which climate change is a hoax or conspiracy.

Some candidates are emphatic in their denial, like the Nevada Republican Sharron Angle, who flatly rejects “the man-caused climate change mantra of the left.” Others are merely wiggly, like California’s Carly Fiorina, who says, “I’m not sure.” Yet, over all (the exception being Mark Kirk in Illinois), the Republicans are huddled around an amazingly dismissive view of climate change.

A few may genuinely believe global warming is a left-wing plot. Others may be singing the tune of corporate benefactors. And many Republicans have seized on the cap-and-trade climate bill as another way to paint Democrats as out-of-control taxers.
