I don't really understand why people still talk about impeachment. It has been very clearly shown to be a futile formality that only makes the ones doing it look even more powerless and worthy of mockery in the eyes of the other side and their supporters. In a bygone era, impeachment would rely on concepts of shame, responsibility and public duty - it would be unimaginable that person that was impeached does not step down from the position and likely from political foreground fully - from the moral and social weight of that consequence. We've seen last 2 times how thoroughly that weight no longer exists in modern society/politics. Without criminal responsibility, there is no responsibility left at all.
