To be frank, the only thing I get about Christian support for Donald Trump is that it might turn out that some of his policies will be good for middle America. Otherwise I am at my wits end as to why Christians view Trump so favourably. (Yes, I know, some readers here are supportive and have explained their support. I remain a puzzled non-Trumper).
Anyhow, this article may be of interest to you, whether you love 'im or hate 'im or simply worry what he will do.
