The first theory is that Donald Trump is popular among religious voters because other things have replaced religious belief as a motivating factor for how people vote, even for religious people. And the dwindling number of Republican voters who do still oppose Donald Trump out of religious conviction can expect the right to turn on them with a vengeance.
The second theory is that Donald Trump’s popularity among religious voters is confirmation of Ross Douthat’s thesis that we have become “a nation of heretics,” not in the classic Protestant vs. Catholic sense, but in the sense that much of what we call Christianity in America—whether Protestant or Catholic, liberal or conservative—has ceased to be Christianity in even a bare bones C. S. Lewis/Mere Christianity way. By this reading, the New Age-y or Prosperity Gospel ideologies in our churches have diminished our powers of discernment and softened us up for Donald Trump.
I am sympathetic to this view, but there are some important signs that contradict it. Douthat has a whole chapter against Glenn Beck, for instance, and Beck is actually the last man standing against Donald Trump in Conservative Big Media. And I am not aware of a single Catholic equivalent to, say, Trump supporter Jerry Falwell, Jr. Many Catholics do support Trump but I cannot name a single prominent Catholic leader who supported Trump prior to his becoming the presumptive nominee.
