The phenomenom of a Trump supporter is a mystery to me. My forays into psychology (at a low level) say that there is going to differing and multi-layered reasonings. This article follows that thinking quite well.
True it that forces have had several decades to change mindsets to became a political movement. However, I'm not sure they had a coherent plan. They just spouted something off and found they could get a little fame and money, so they kept doing it. Beats working at the beef packing plant, right? I doubt they read any psychology books and applied any psychological principles to their musings.
And true it is that a few decades will be needed to turn around this mindset. I don't have an easy answer for that--or maybe better said, an answer from current American democracy.
As you know, I am advocating an alternative system of governance. The foundation of this TDG system is the neighborhood, where about 200 people are living in a geographic community to form an electoral unit. If one of these communities wants to elect a trump mindset, that would be their right. But as that representative starts working with other elected reprensentatives, they would find him/her not worthy of advancing up the tiers.
As a politician in this TDG works his way up the tiers, he/she has proven skills and attitudes towards governance that deserve the promotion.
Unfortunately, USA will need about two decades to build this system so that it can take over responsibility and authority of governance. When I see dancing in the street for the Biden/Harris win, I see a lot of wasted energy that could have gone to better places.
