I think it's more that strong men leaders get backers when the majority want them. All kinds of leaders are out there at all times, people swap their support to whichever they feel like at any given time. So when times get tough, half the population will side with power concentration, primitive but simple leadership structures. The other half want power decentralized and consensus to be required, the agreement of the majority, not be left with obedience to authority, which eliminates the ability for consensus or agreement. Nobodies needs matter except the needs at the top.

It's actually probably absolutely necessary that the GOP see Trump as sharing their interests. If you had to give up your power, you'd want to give it to whoever shares the most do your interests, so their exercise of power is more likely to benefit you. You wouldn't willingly give to to someone whose interests were furthest from yours. And what an irony that Trump has convinced them their interests align. If we could break that assumption, people would find it much harder to hand over their power. But since Trump literally doesn't care if he collapses America, he's willing to give them things they want, regardless of the wisdom of it.

God the GOP are the fucking worst.
