This is a long, but incredibly good, read. More than just an explanation of why evangelicals sold their souls to Trump, it's a fascinating history of the varieties of religious political activism in the US. The one section that caught me up short was this discussion of Christianity and science with its absolutely brilliant counterfactual:
"Moreover, in making their case on cultural decay and decline, evangelicals have, in some highly visible cases, chosen the wrong nightmares. Most notable, they made a crucial error in picking evolution as a main point of contention with modernity. “The contest between evolution and Christianity is a duel to the death,” William Jennings Bryan argued. “If evolution wins … Christianity goes—not suddenly, of course, but gradually, for the two cannot stand together.” Many people of his background believed this. But their resistance was futile, for one incontrovertible reason: Evolution is a fact. It is objectively true based on overwhelming evidence. By denying this, evangelicals made their entire view of reality suspect. They were insisting, in effect, that the Christian faith requires a flight from reason....
What if Bryan and others of his generation had chosen to object to eugenics rather than evolution, to social Darwinism rather than Darwinism? The textbook at issue in the Scopes case, after all, was titled A Civic Biology, and it urged sterilization for the mentally impaired. “Epilepsy, and feeble-mindedness,” the text read, “are handicaps which it is not only unfair but criminal to hand down to posterity.” What if this had been the focus of Bryan’s objection? Mencken doubtless would still have mocked. But the moral and theological priorities of evangelical Christianity would have turned out differently. And evangelical fears would have been eventually justified by America’s shameful history of eugenics, and by the more rigorous application of the practice abroad. Instead, Bryan chose evolution—and in the end, the cause of human dignity was not served by the obscuring of human origins."
