I don't really buy into the cult characterization. It's too easy and misses the point. The reason Trump supporters seem to support him despite his offensive persona isn't because they worship him. It's because he "fights back" against Democrats. They hate Democrats and as long as Trump is flipping them the bird, the details won't matter.
The reason I and everybody I know who supports Trump is not because he is likable or revered--many of us find him often offputting--but we support him because he is the ONLY President of our lifetime who actually cared whether he kept his campaign promises and had the courage to try and try again to accomplish them. All others if they failed once, put it on the shelf, shrugged, and said "I tried."
He delivered on the economy producing an economy that was lifting all boats in ALL demographics, even the hardcore unemployed.
He delivered on fighting back against the hordes of migrants invading our country and had that slowed to a trickle. If the feckless never Trumpers in the GOP and Democrats had given a rat's ass about that and given him any help at all, he would have had it completely under control.
He had all our allies understanding that they couldn't count on the USA being their ATM or sugar daddy any more and would have to hold up their end. They hated him for that but they respected him. In the process he pulled us out of one sided, unwise agreements and revamped trade policies to put America on equal footing again instead of being the world's patsy.
North Korea stopped firing provocative missiles over South Korea and Japan, China, Russia, Iran all stopped saber rattling, the war in Syria ended, the war in Afghanistan was being carefully and wisely wound down with the Taliban no problem to anybody, and three Arab nations normalized trade relations with Israel. We had the closest thing to world peace any of us had ever experienced.
Biden has reversed almost all of that, wars raging and we're teetering on the brink of WWII, family wealth and buying power has taken a severe hit, the economic benefits still in place will go away in 2025 if we do not put a savvy Republican into office, and the vast majority of the country thinks we're headed in the wrong direction.
Those who vote for a personality will continue to malign and hate Trump. Those of us who vote for good results and effects will vote for him again.
