But there is no basis for saying that the United States is somehow “not a democracy, but a republic.” “Democracy” and “republic” aren’t just words that a speaker can arbitrarily define to mean something (e.g., defining democracy as “a form of government in which all laws are made directly by the people”).nd the United States is therefore also a constitutional republic. Indeed, the United States might be labeled a constitutional federal representative democracy. But where one word is used, with all the oversimplification that this necessary entails, “democracy” and “republic” both work.
