I am not the first person to point this out: There’s been a cultish quality to President Trump’s most ardent supporters. He seemed to acknowledge the phenomenon when he boasted that he could “stand in the middle of Fifth Avenue and shoot somebody” and not lose voters.

Throughout the campaign, and in personal appearances since then, Trump has harnessed the kind of emotional intensity from his base that is more typical of a religious revival meeting than a political rally, complete with ritualized communal chants (“Lock her up!”).
