Dangerous times for Trump if he faces into process of impeachment

I’ve followed and studied politics all my life. I believe I can contribute to most discussions about how it is practiced, about what it means, about its positives and negatives. I’ve known great politicians and weak ones, nice ones and vicious ones, charming ones and ones with so little charm you’d wonder how they could ever get elected to anything.
I’ve had heroes and villains. And I have never, in a reasonably long and active life, known anything like the phenomenon of Donald Trump.
