I generally agree with you, but the whole thing persevered quite well through one Trump term already, and I doubt it will be different this time. It's simply very difficult to break someone out of that sort of worldview once they fall in. Their brain will literally rebel against any suggestion that they've been hoodwinked from the start. So instead they'll grasp for whatever justification is offered.
Sort of like how we've how had literal centuries of people claiming that they've decoded the bible and that the second coming and/or rapture are happening any day now. Another one crops up every few years, and sometimes the people who make such a prediction and are proven dead wrong will just say "oops, slight miscalculation, it's five years from now" and most of the people who believed in them before just keep right on believing. Rather than confronting the realization that we are mostly unimportant people doing unimportant things, which a lot of people can't really handle mentally, it is intoxicating for many people to believe that they're part of something special and important. And they'll do whatever it takes to go right on believing that.
