I see this very often and am just noting it in response to your post.
So often people try to attribute rational ideas to Trumpists (or really any third party) to square the circle and resolve seemingly irreconcilable beliefs, or actions seemingly irreconcilable with beliefs (and assign people to the category of “crazy” when this cannot be plausibly done). This is basically what Daniel Dennett identifies as “The Intentional Stance.” We generally attribute beliefs to others based on what it would be rational for them to believe, including a whole panoply of background beliefs it would be “rational” for them to have. We do this to dogs, thermostats, people, whatever. However, many people, or all people in some situations, do not even have “standard” beliefs in some kind of verbal, propositional sense, they simply react to the world based on some general, often entirely underdeveloped, framework and then articulate beliefs afterward if asked.
From a third-person perspective you can assign to me an infinite number of “verbal” beliefs, such as my “belief” that the average screwdriver is smaller than the average couch. However, I have never entertained that belief until now–it was never in my head–even if I would act as if it’s a deeply held belief if faced with a situation where it were relevant or I had to explain myself.
I say this because when we attribute beliefs to others we need to “verbalize” them in some kind of concrete way, using commonly understood words that have, if not a precise meaning, a generally understood meaning among informed members of a language community. So much effort in trying to explain Trumpists is trying to offer some kind of rational mode of analysis, but I think this just fails because they don’t understand government, society, the constitutional role of the president, the history that led us to the present, etc.
I don’t have a highly developed point here, that would take a lot more work, but what I see in Trump and apologists is not so much some A-B-C rational process, even if it involved not classifying some oligarchs as “oligarchs”, but just more primitive and emotive reactions that need to be explained in terms of deeper motivations (“supporters good, immigrants bad; hate them liberal pussies; Jesus is Lord and he will save me and has chosen Trump as his vehicle”). The “beliefs” these people have are downstream from their barely articulated, even to themselves, “worldview”. They are not coherent because they are not explicit or well informed. This is what the anthropologist Arlie Russell Hochschild unhelpfully calls their “deep story.” What a liberal sociologist learned from spending five years in Trump’s America | Vox I would say it’s an account of why the world is a conspiracy against them, as articulated by Fox News, etc, and that explains the condition of their lives.
I would note that in trying to understand fascism as a political philosophy it seems to mostly be like this. It’s not so much an actual political philosophy as an expression of how one might want the world to be, along with blame and efforts against those presumed to be interfering with it being that way (when the real cause is more akin to reality just being reality). This leads to fascism ultimately being the vaguest political program possible, such as “make America great again!” or “I will be your retribution” which means literally nothing but appeals to the emotional longing of people who feel alienated by the world. That is why Trumpism is an ideology by and for losers and those, generally losers themselves, who grift off them.
