Laws mean something only if there are people willing to enforce them
The Founders never envisioned that the citizens would elect a man with no ethics. A man who would not follow the law. At one time the media was well enough balanced between left and right to get the word out to people. Now it’s not. They never envisioned a situation where the balance of powers among the arms of government would be so ignored…The Founders could not have envisioned an electorate that was so ignorant of the process of government and their important role in it.
I agree that the Founders could not have envisioned the exact details of what’s happening now. But I think the Founders knew that something of the general sort was a distinct and perhaps even likely possibility. The Founders were not naive, and they were students of both history and human nature. They tried to design a government that protected liberty as best it could, knowing it might not succeed and that there would always be highly-motivated forces working against it.
