 The concept of political representation is misleadingly simple: everyone seems to know what it is, yet few can agree on any particular definition. In fact, there is an extensive literature that offers many different definitions of this elusive concept. [Classic treatments of the concept of political representations within this literature include Pennock and Chapman 1968; Pitkin, 1967 and Schwartz, 1988.] Hanna Pitkin (1967) provides, perhaps, one of the most straightforward definitions: to represent is simply to “make present again.” On this definition, political representation is the activity of making citizens’ voices, opinions, and perspectives “present” in public policy making processes. Political representation occurs when political actors speak, advocate, symbolize, and act on the behalf of others in the political arena. In short, political representation is a kind of political assistance. This seemingly straightforward definition, however, is not adequate as it stands. For it leaves the concept of political representation underspecified. Indeed, as we will see, the concept of political representation has multiple and competing dimensions: our common understanding of political representation is one that contains different, and conflicting, conceptions of how political representatives should represent and so holds representatives to standards that are mutually incompatible. In leaving these dimensions underspecified, this definition fails to capture this paradoxical character of the concept.
