Why the left cares about Rick Perry's views on evolution

Progressives like to cloak their policy preferences in the mantle of science, but they do not in fact give a fig about science, which for them is only a vehicle to be ridden to the precise extent that it is convenient. This is why they will ask what makes Rick Perry qualified to disagree with the scientific establishment, but never ask the equally relevant question of what makes Jon Huntsman qualified to agree with it. So long as they are getting the policies they want, they don’t care. If you want to see how dedicated a progressive is to dispassionate science, spend two minutes talking about the heritability of intelligence. You’ll be up to your neck in witchcraft and superstition and evasion in no time at all. (If you want to test a progressive’s faith in rigorous scholarship more broadly, ask him about gains from trade and comparative advantage, realities that are as solid as anything social science has to offer.)

Perry is making an error by approaching these questions as though they were scientific disputes and not political ones. The real question about global warming isn’t whether one computer simulation or another is the better indicator of what our climate will be like a century hence, it is whether such policies as envisioned by the environmentalist-anti-capitalist green coalition are wise. They are not. Evolution is a public question not because politicians have anything intelligent to say about the science, but because the question provides a handy cudgel to those who wish to beat the Judeo-Christian moral tradition into submission in the service of managerial progressivism.
