the best article I've read this week.
So, here we go. I point you to "Impeached by the Facts." November 6, 2019. You can read the article for yourself, on-line, for free. Just click on the link.
A quick recap of the key point: the President works on the premise that he can do anything he wants. That includes denying facts. Not that facts don't exist. Rather, that they don't matter because the President can do anything he wants.
I judge the article to offer fine analysis of the political situation in the U.S. Though I've recapped it, it's well worth your reading it in its entirety.
