I don't see any parallel. Clinton had an affair with a staffer WHILE he was office. Trump has not. And the only reason Clinton was impeached was because he perjured himself by lying about. Had he not lied, nothing would have happened. And if Congress was supportive of him, which they were not because he was considered an outsider (like how could a nobody Arizona governor become president), he never would have even been impeached despite the perjury.
My reference to commonality was regarding the sequences, parties and players that led to impeachment. How each party on the offensive leveraged whatever they could, how the investigation proceeded, how each president defended themselves, expressed themselves, the press and how they felt about it. How both parties reacted along the way and the feeling behind it. There were times during the lead up in that documentary where I felt like I could substitute the party and the win at all costs mentality.
Please don't misunderstand....I'm not taking sides....just commenting on how, as that documentary proceeded there were so many times where I said "That's the same thing, feeling, etc. as what's happening these days" but the parties are reversed.
I was not referring to any commonality in the validity of the cases then, the ones folks think are possible today, character of the accused, etc.
