The apocalyptic rhetoric that regularly escapes the bounds of civil discourse at Trump events is fueled by the particular energies that are unleashed when a long-dominant group senses the looming end of its era. Certainly, the boarded up shop fronts of small towns that testify to the disappearance of reliable working class jobs are a critical part of this sense of loss and distress. But the watershed moment that many analysts have missed, and that Trump’s most ardent supporters feel in their bones, is this: During Barack Obama’s tenure as president, the United States has crossed the threshold from being a majority white Christian country (54 percent in 2008) to a minority white Christian country (45 percent in 2015). The passing of a coherent cultural world — where working class jobs made ends meet and white conservative Christian values held sway — has produced this powerful politics of white Christian resentment.
