For sure, the “Law of Intended Consequences” will play a big role as the drama unfolds. For sure, no one is really in control of the writing of this script.
A few years back, I saw a documentary about how a group of circa 1940 American psychologists/psychiatrists analyzed Adolf Hitler from his media clips and speeches. The goal was to try to predict his handling of WW2. Their conclusion was that he would take Germany to the brink of total destruction rather than surrender AND he would commit suicide. Despite no hands-on with Hitler, these professionals got Hitler right.
It seems to me that similar analyses can be used to predict Mr. Trump’s behavior. For example, the D’s can use the psychology and psychiatry professions to find ways of upending Mr. Trump in 2020. Maybe they are already are.
