I read an article in Foreign Affairs that calls this "personalism."

This one I presume? https://www.foreignaffairs.com/world/new-dictators

Notice the date -- 2016. This has been brewing for a long time, and I will never forgive / forget that the people who recognized it and called it out early [1] were mocked and ridiculed to no end. They were shunned in their professions, called alarmists, and liars. But they were right the whole time, they were just ahead of the curve. If we had just listened to them, this could have all been avoided.

(also from 2016, as far as I know the first person to make the connection between Trump's narcissism and his inevitable attempt to become a dictator. She predicted January 6 five years before it happened just by pattern matching his personality disorder to dictators of the past).
