At certain times Donald Trump has seemed like a budding authoritarian, a corrupt Nixon, a rabble-rousing populist or a big business corporatist.
But as Trump has settled into his White House role, he has given a series of long interviews, and when you study the transcripts it becomes clear that fundamentally he is none of these things.
At base, Trump is an infantalist. There are three tasks that most mature adults have sort of figured out by the time they hit 25. Trump has mastered none of them. Immaturity is becoming the dominant note of his presidency, lack of self-control his leitmotif.
