The American church (evangelical/fundamental/conservative) leadership has been mum on this going back to the moral majority days. While policy (abortion) was always the rallying cry, it was obvious to me that the closer they got to power the less they had to say about the eternal issues that are the core of the church's mission. Now with the church wedded (yoked you might say) to the GOP the party tells the church what to believe. Ronald Reagan was the first recipient of the church's adoration. Today he would be tarred with the RINO label. Where is the steadfast commitment to truth if it can be changed at any time? Orwell gets a lot of attention about 1984 but what I have witnessed is more along the lines of Animal Farm.
As for Mr Trump, Dr. James Dobson claimed in the lead up to the 2016 election that he was present with Mr. Trump when he made his salvation prayer to Christ. It apparently didn't give him any sense of security if he is still "hoping" that he gets in to heaven.
