It's all a conspiracy by the powerful natural history museum lobby.
There's a new Public Policy Polling poll out identifying Scott Walker as the top Republican pick among their presidential maybe-candidates. But some of the other poll results among self-identified Republicans are doozies. For example
• 49 percent of Republicans say they do not believe in evolution. Only 37 percent say they do.
• 66 percent of Republicans say they do not believe in global warming. Mind you, even the most science-denying Republicans in Congress have said they "believe" in global warming, they just don't think we should do anything about it. Their base has not yet reached this enlightened state.
• 57 percent of Republicans would support establishing Christianity as our "national religion."
So it would seem that Scott Walker indeed has the conservative id pegged, and that Republican candidates seeking primary frontrunner status will indeed need to learn to embrace a base that at this point has become very conspicuously stupid. People for whom even the basic sciences are conspiracies if it goes against what they would rather believe to be true. People who love America very, very much, but have never cottoned to the religious freedom part that was so obsequiously drilled into them in grade school as the very reason the people with the belt-buckle hats chose to settle on this landmass to begin with. People who consider Bill O'Reilly to be an upstanding individual.
Welp, now I'm depressed.
There is hope, I suppose. Sixty-six percent of Republicans don't actually know thing one about "global warming," for example, they just know they're supposed to be against it because the angry-sounding guy on the radio was pretty clear on that subject. There's nothing inherently conservative or Republican about that position, it is just the reactionary fad-of-the-moment, and it will likely change back when another sufficiently belligerent shouter comes along to shout the opposite stance. Or not, if the loathing of "science" as an entity has simply overtaken all the other conservative neural pathways.
As for the others, yep, we're likely doomed. The thinking of the Republican base goes that we need to establish religious law in this country because otherwise we'll be taken over by people who somehow convert us all and make us live under their religious law, and wouldn't that be bad. Then we'll burn down all the natural history museums because they are offensive to Our Lord, by which I mean whoever grovels to the base enough to win these upcoming primaries.
