I'd love to know who the "many" people are who have met Trump who have been positively impressed by him after meeting him and changed their minds about him in a positive way. To the contrary, most of what I've read since 2016 have been people who had never met or dealt with him before who come away very unimpressed and even alarmed at just how narcissistic, self-absorbed, easily distracted and bored, and distanced from reality he is about nearly everything.
Like Tony Schwartz, the ghostwriter that Trump hired to write his bestselling The Art of the Deal in 1987 who spent 18 months with Trump writing the book and later said that he regretted adding to the false "Trump is a great businessman" legend. In 2016 Schwartz went around telling anyone who would listen that Trump wasn't qualified to be POTUS, and he knew because he'd spent 18 months with the guy and knew what he was like.
