What I don't understand is that Nixon was never impeached. He was investigated and when that investigation got to the point where his criminality was plain as day, and the Republican realized that a successful impeachment was imminent, he resigned.
Now I suspect that under similar circumstances Trump will not resign, but that's not the point. The Republicans had come to the conclusion that his criminality was as plain as day.
That's what needs to take place, an investigation that makes it plain as day to everyone just what a criminal and traitor he really is.
Just think about that going into the next election, one party trying to hold a criminal traitor to account, and the other party defending him.
Not a bad position to be in if you hold America dear.
