Most democracies are representative. Elected by the people, representatives constitute a legislature and create laws. This is typically done through voting. This raises an interesting question of institutional design: should our representatives vote transparently or by secret ballot? No contemporary philosopher, to my knowledge, has addressed this question. In this chapter I argue that if we take seriously the value of political equality—a normative ideal that nearly all democratic theorists embrace—then voting among representatives in a legislature ought to occur by secret ballot. Representatives should vote just as citizens do in elections. Democratic equality, I argue, thrives in darkness.
