I was raised Baptist, a denomination that dates all the way back to around the time of the Civil War or so, but nobody's exactly sure because nobody bothered to keep track or remember anything. This type of evangelical Christianity is distinctly American, which shows in its outright xenophobic, fundamentalist extremism. It's the religion we needed to justify slaughtering all those Indians and Manifest Destiny. But Baptists themselves actually believe they are practicing "original" Christianity, and will go to great lengths to draw surprisingly fabricated lines through a mostly fictional history all the way back to John the Baptist, because, you know, he was "the Baptist" in exactly the same way they are Baptists. You can tell because it's the same word. In English.
Anyway, there's a very large cult of the End Times among Baptists and more or less every other evangelical strain of Christianity. Only the denominations with recorded history dating back farther than 1825 seem to be immune -- Lutherans, Methodists, and Catholics of course. But the vast majority of American Christians are "evangelical", meaning they believe any history that runs contrary to what they learned in Sunday School is not only false, but an outright conspiracy to bury the truth and persecute them. They literally meet disagreeing beliefs and actual evidence in a way that strengthens their faith because, to them, it's only evidence of how "tricky" Satan is, and how they're the smart ones because they see through all those confusing numbers and experiments and clinical trials and... I digress, but yeah, America has the End Times Disease real, real bad.
As for this particular election, I honestly don't think it was that religious. The only function religion served last month for most Trump voters was to conveniently buckle and give way without so much as a peep. This was a very blatant, very deliberate backlash against Obama and against everything he and his supporters represent. It was an outright assault on multiculturalism, on liberal values (both modern and classical, no matter what these people try to tell you), on every conceivable type of equality. They viewed it as a referendum on the last hundred years of progress, and they rose up and smashed it to pieces. Their religion, insofar as it was involved at all, was more like a cheerleader than a band leader.
