Here's my take. If you have to look at what happened and say that when he did this that fits the definition of this other thing, what you have is a nothingburger.
So, when he used the word "though" in a sentence, that clearly meant that there was a connection between this and that, and that means it was extortion, which is really bribery, which is impeachable and...……..where were we?
Nixon held out a long time against that sort of thing. Finally, though, he had to release a tape where he was saying, "What if we gave this guy a million dollars to not testify?" (Not a direct quote, but not a distortion of what was said, either.) At that point, his public support vanished, and his congressional support dried up at the same time.
Find a crime that The Donald has committed that you don't have to explain to ordinary people why it's a crime, and then you'll have something that can win.
