There was another post more insightful about this than mine, but I think this is simply for the fact that Trump is super rich. Forget about whether he's worth 8 or 4 or 3 billion, that's super rich, and for a vast swath of people in this country, getting super rich is literally their end state. For them, being rich means you have succeeded, and the way you got rich is unimportant.
For these people, it's very possible that Trump is very much a God in their eyes. A being that has ascended to a higher plane and is to be idolized, and who is beyond reproach. Anyone who demeans Trump is a heretic.
