 Williams offers her understanding of representation as mediation as a supplement to what she regards as the traditional conception of liberal representation. Williams identifies two strands in liberal representation. The first strand she describes as the “ideal of fair representation as an outcome of free and open elections in which every citizen has an equally weighted vote” (1998, 57). The second strand is interest-group pluralism, which Williams describes as the “theory of the organization of shared social interests with the purpose of securing the equitable representation … of those groups in public policies” (ibid.). Together, the two strands provide a coherent approach for achieving fair representation, but the traditional conception of liberal representation as made up of simply these two strands is inadequate. In particular, Williams criticizes the traditional conception of liberal representation for failing to take into account the injustices experienced by marginalized groups in the United States. Thus, Williams expands accounts of political representation beyond the question of institutional design and thus, in effect, challenges those who understand representation as simply a matter of formal procedures of authorization and accountability.
