In this book, Posner argues that democracy is best viewed as a competition for power by means of regular elections. Citizens should not be expected to play a significant role in making complex public policy regarding, say, taxes or missile defense. The great advantage of democracy is not that it is the rule of the wise or the good but that it enables stability and orderly succession in government and limits the tendency of rulers to enrich or empower themselves to the disadvantage of the public. Posner's theory steers between political theorists' concept of deliberative democracy on the left and economists' public-choice theory on the right. The book argues for law and democracy as twin halves of a pragmatic theory of American government.
