The question is often asked, who is the worst president of all time? Surprisingly, you’re going to get a lot of overlap between mainstream left and right. They may disagree on specifics but look at any “best presidents” list and you will find that “do something” presidents always rank near the top. Presidents who waged war and governed as a monarch always rank high. “Forgettable” presidents who presided over times of peace and prosperity tend to rank lower. This is wrong. We should not rank presidents by how famous they are. We should not judge them based on whether they did unconstitutional things that we like or don’t like. There is one single metric for measuring how good a president was: Did they uphold their oath to defend the constitution? Based on that, who is the worst?
