The ones in my family or that I have been close to emotionally in the past are people I genuinely like(d), but I would say the ones I know can tend to be abstract to the point of not being 100% grounded in reality. The ones I'm close to have extremely unrealistic notions of reality and interestingly enough tend to mooch off of others financially (but I think that's a random correlation). That last point is related to their inability to identify everything going on in reality, all the practical cause-and-effects. Most have a parent who is extremely manipulative and even emotionally viscous with whom they have a strained relationship. In one case I think his connection to Trump resolves his father issues who happens to be very similar to Trump. They also all happen to live most of their lives in video games, so are a bit reality optional. They also have pockets of deep personal anger that either gets compartmentalized or pushed into the subconscious.
One will post these horrifically racist posts that disparage a racial group who is horribly oppressed as though they are liars and oppressors, but then comes back with these "lets all have peace and love in the world" extremely idealistic philosophical notions, so he is deeply compartmentalized and dichotomous. Another is also deeply dichotomous psychologically strongly pushing a personalized moral agenda for medical research, but readily has enough rage to want anyone or system destroyed who threatens something he values. Another one is quiet and reasonable, but surrounded by Trump supporters environmentally. He feels quite beat down by life and so doesn't trust the societal measures to re-establish racial equality.
I think in each case of the ones that I know, they feel cheated and betrayed by life, suppressed and not heard. but also have quite a bit of privilege and advantage. They have a lot of anger, but it is not fully processed consciously. I think they see Trump as being bullied, capable of saying the wrong thing socially like them, being angry like them, being beat down in certain ways like them, and they don't have direct empathy or contact with the demographics that Trump suppresses, so they block out the bad stuff he does and says and instead they identify with him as socially off, bullied, and fighting for dominance in ways that no one is acknowledging feels lost to them.
