Much contemporary political philosophy emphasizes the distinctiveness of political issues from moral issues. In contrast, utilitarianism seems to treat political issues as a mere subset of moral issues. It also seems to fit a technocratic model of politics, according to which political decisions should be left to experts capable of assessing the relevant facts. This chapter argues that utilitarians can give a richer account of politics, and one that is less technocratic, by attending to the normative significance of legitimacy. It outlines a conception of legitimacy as the degree of acceptance of a procedure. Though this is a sociological property and not a normative one, it has considerable normative significance: it describes the limits of what can be achieved without coercion or disorder. Moreover, since democracy is now, in many contexts, a necessary condition of legitimacy, the account of legitimacy bolsters the utilitarian case for supporting democracy.
