this reads like someone who hasn't seen dementia up close. I don't see his behavior as much different than term 1. simply more malevolent.

there's no obvious word searching. he's always been simplistic and unencumbered by the need for logical consistency. he was never a word smith. he has his stock phrases (eg, "many people are saying...<insert lie>"), which he uses as a crutch, but also to great effect.

as someone who HAS seen dementia from a to z, I don't see it here.

He was rude and violent years ago. There is nothing new about those two. They made him win presidency twice.

He is more incoherent and demented.

yes, but this is his administration; full stop neogestapo. Hes surrounded and politically floated by white Christian nationalists. His dementia just lubricates the existing harm vectors.

I mean him being in the throes of dementia is certainly possible; but, more absolutely, he's a fucking asshole. The problem isn't just him, however; it's his entire administration, Congress, and the SCOTUS he stacked that further enable the insanity.
