You occasionally find folk who have at least heard of the Federalist Papers, but it is extraordinarily rare (in my experience anyway) if you actually find someone who has heard of the Anti-federalist's writings, also known as
Letters from a Federal Farmer. It's actually worthwhile to read them both simultaneously, as they are two sides of an argument, often focusing on the same topics. If you only read the Federalists, you're only getting half of the story.
