 Before one even asks whether “one person, one vote” is the right policy, one needs to determine just who counts as part of the demos. Call this the boundary problem or the problem of constituting the demos (Goodin 2007: 40; Ron 2017). Democracy is the rule of the people. But one fundamental question is just who constitutes “the people”. This is no small problem. Before one can judge that a democracy is fair, or adequately responds to citizens’ interests, one needs to know who “counts” and who does not.
