FWIW, when the press uses the word “temperament” against Trump, they are not using the normal defintion of the word. It is a catchall for everything from bad judgment in general, to being bigoted, to being a hot-head, to being intemperate in remarks, and probably half a dozen other things. It’s a catch-all phrase, similar to how “not fit” is not limited to referring to physical and mental health.
I hadn’t thought about that, but I think you are absolutely correct. Thoughtful and good post - thank you!
