You know this, right?
"I often hear people argue that the United States is a republic, not a democracy. But that’s a false dichotomy. A common definition of “republic” is, to quote the American Heritage Dictionary, “A political order in which the supreme power lies in a body of citizens who are entitled to vote for officers and representatives responsible to them” — we are that. A common definition of “democracy” is, “Government by the people, exercised either directly or through elected representatives” — we are that, too...The United States is not a direct democracy, in the sense of a country in which laws (and other government decisions) are made predominantly by majority vote. Some lawmaking is done this way, on the state and local levels, but it’s only a tiny fraction of all lawmaking. But we are a representative democracy, which is a form of democracy."
