Elizabeth Dias has a long booklet-like article “Christianity Will Have Power”, with photographs and video by Jenn Ackerman and Tim Gruber, in the New York Times. The subtitle is “Donald Trump made a promise to white evangelical Christians, whose support can seem mystifying to the outside observer” – as if from relativity theory.
It does describe their “trust” in Trump as their belief that he is there (perhaps proto-fascist) bully to keep minorities in line who have threatened to erode their own social hegemony.
