Christians aren't interested in being seen as morally superior, that's the philosophy that undergirds leftist or liberal thought and every policy they advocate for. The argument is whether or not those liberal policies are either A. Effective or B. Simply a strategy to win votes and gain power.
Conservative Christians have really only applied morality to two issues In the last decade or so, abortion and gay marriage. The other things like taxes or healthcare were never moral stances. However EVERY single liberal stance is chosen for a "moral" purpose. Higher taxes to steal from the thieving rich to give to poor, healthcare to for all the helpless, gay marriage for the poor gays who can't call themselves married, open borders for people unfortunate to be born outside US, abortion for all those poor women who couldn't figure out how not to get pregnant that would ruin their career chances, money for black people who were slaves 150 years ago, and on and on and on. Only one party tries to claim to be morally superior, and it ain't on the right.
The whole trump accord with evangelicals was originally a "lesser of two evils" but he kept his word. In fact he's probably the most pro life president ever in looking at record. There's a parable in the Bible that talks about the two sons doing what their father tells them, the first son is asked to work in the field and says yes but then doesn't, the next son says no but eventually goes into the field to work for his father. Only one of the sons actually did the fathers bidding. Trump may be a personal failure morally but he's done the bidding of his voters.
I do agree with OP in that trump supporters are very enthusiastic, even more so than Obama's, which I would never have thought I'd see in my lifetime on the right after Obama's sycophants. As someone currently in academia who doesn't have a voice I'm grateful for their enthusiasm, because although I disagree with trump on many things especially his hubristic antagonism on Twitter, the leftist mobs make me ever so grateful for his refusal to back down even one inch to placate them.
