Political Equality and Geographic Constituency

Geographic definitions of constituency—the set of voters eligible to vote for a representative—have been criticized by theorists and reformers as undermining democratic values. I argue, in response, that there is no categorical (or even generally applicable) reason sounding in political equality to reject geographic districts. Geographic districting systems are typically flexible enough that, when properly designed, and matched with an appropriate electoral system, they can satisfy the requirements of political equality. More generally, I argue that it is a mistake to evaluate the egalitarian character of constituency definitions in isolation from the political decision-making process as a whole. While it is conceptually important that we can detach constituency definition from other features of electoral systems, when it comes to normative and evaluative judgment, we ought to judge holistically. When we do so, we will rarely find general reasons to prefer one type of constituency definition to another. Geographic districts may offer benefits of logistical convenience and information circulation, even given the existence of advanced information technology. The best reason to reject geographic districts is their liability to anti-democratic abuse. Their defensibility in any given polity thus depends on how feasible it is to protect against such abuses while retaining a geographic districting system.
