Many observers, me included, have been befuddled by the support given by white evangelicals to Donald Trump. His life and his rhetoric, don't seem to fit what an evangelical would give approval. In this essay from Sightings, journalist and scholar Theo Anderson gives the most cogent response I've yet seen. I commend it to you. It's not the policies, it's the anti-establishment rhetoric that is drawing support. I might add there is a similar trend among liberal Christians supporting Bernie Sanders. There is the feeling that the establishment has betrayed their trust and thus Trump's run offers them an opportunity to punish the establishment.
