Chet -- We've discussed this before. You are conflating the authoritarian personality with charisma. Sure authoritarians can also be charismatic, but not in Donald Trump's case. Again I will refer you to characteristics of charismatic people as listed in Time magazine:
10 Habits of Remarkably Charismatic People
1. They listen way more than they talk. They ask questions. They maintain eye contact. They smile, frown, nod. They only speak when they have something important to say–and always define important as what matters to the other person, not to them. I don't see that in Trump. He speaks about what is important to him and his big enormous ego.
2. They don’t practice selective hearing. Remarkably charismatic people listen closely to everyone, and they make all of us, regardless of our position or social status or “level,” feel like we have something in common with them. Trump has a short attention span. He cannot even stand to participate in the daily intelligence briefings. In press conferences he hears only parts of questions and jumps to conclusions quickly.
3. They put their stuff away. They are not easily distracted but give you your full attention. When Trump talks he is distracted by someone he sees in the audience and will suddenly call out his name and a story. All his press conferences are rambling distractions of what comes to his mind at the moment.
4. They give before they receive — and often they never receive. Giving is a way of establishing a real connection and relationship. Trump's only "giving" is money to buy a vote.
5. They don’t act self-important…The only people who are impressed by stuffy, pretentious, self-important people are other stuffy, pretentious, self-important people. The rest of us aren’t impressed. We’re irritated, put off, and uncomfortable. I for one am irritated, put off and uncomfortable with Trump's presence. His authoritarian followers, however, will worship him for his authority.
6. …Because they realize other people are more important. Charismatic people understand that you can’t learn anything from yourself. Therefore, they value the opinions of others because they’re people they can learn from. Trump on the other hand says, "I alone can fix this'." He continually says "I am smart"...smarter than the generals.
7. They shine the spotlight on others. While Trump goes on stage he'll pander to the people in his audience. It's not genuine praise with sincerity. The only person Trump shines the spotlight on is himself as he brags about everything he's done...never uses the term "we".
8. They choose their words. In associating with happy, enthusiastic, fulfilled people they choose words that can help other people feel better about themselves. I don't see that anyone on Trump's team is really happy...none ever smile and none feel good about themselves...Kellyanne Conway, Sean Spicer, others. No happiness there emanating from the charisma of the boss.
9. They don’t discuss the failings of others… Do I need to even elaborate?
10. …But they readily admit their failings. Incredibly successful people are often assumed to have charisma simply because they’re successful. Their success seems to create a halo effect, almost like a glow.
Keyword is seem.
You don’t have to be incredibly successful to be remarkably charismatic. Scratch the shiny surface, and many successful people have all the charisma of a rock.
I think that last statement defines Trump to a tee. He has all the charisma of a rock.
