This isn’t the first time we’ve seen last-ditch efforts to persuade an audience by making comparisons to Nazism. This time, Vermont Senator Bernie Sanders is comparing skeptics to those who ignored the rise of Nazism in Germany the 1930s.

At a Senate hearing Tuesday, Sanders said:

“It reminds me of an event that took place in this country and around the world in the late 1930s. During that period of Nazism and fascism’s growth-a real danger to this country and democratic countries around the world- there were people in this country and in the British parliament who said ‘don’t worry! Hitler’s not real! It’ll disappear!”

Weather isn’t Nazism. And even if one believes in man-made climate change, it’s not Nazism either.

And, by the way, we’d say that self-described socialist Senator Sanders is a lot closer to Neville Chamberlain than to Winston Churchill, and would have very likely himself looked the other way as Hitler instituted his national socialist agenda, much as his socialist boss Barack Obama is doing.

But skeptics should really take this criticism with a smile, because when they pull this card, you know they don’t have much left.
