The reason why I labeled "Faustian pact"for evangelicals in the thread's title, is this.
Evangelicals...as a "religious" group think that they need political protection (from Muslims, from the gay/lesbian community, from those Constitution scholars who want to separate religion from governmental policies, etc.) and have sought such "protection," from the least traditionally religious president in living memory.
Trump may be the "least traditionally religious president in living memory".
But that does not mean that he was not the better choice for the Evangelicals, in the General Election.
That you have trouble understanding why they felt like that is obvious.
That is no excuse for you to assign odd and nefarious trappings to it.
