I haven't posted in a while, but I don't think between March and now there was much need for another round of analysis. I'm not certain that there's a need now.
Here's some background reading.
George Lakoff on "Understanding Trump". George Lakoff is a linguist who works from a neurological perspective. His works focus on how language impacts the brain and how the brain impacts language. He focuses on how the framing of a narrative or comment impacts how people react to it. I would also suggest reading his book "The Political Mind." I think most journalists do a horrible job of framing and political journalists are the worst.
"The Authoritarians" by Bob Altemeyer. The title explains it all and I've posted this link previously.
