Plural voting and political equality: A thought experiment in democratic theory

I demonstrate that a set of well-known objections defeat John Stuart Mill’s plural voting proposal, but do not defeat plural voting as such. I adopt the following as a working definition of political equality: a voting system is egalitarian if and only if departures from a baseline of equally weighted votes are normatively permissible. I develop an alternative proposal, called procedural plural voting, which allocates plural votes procedurally, via the free choices of the electorate, rather than according to a substantive standard of competence. The alternative avoids standards objections to Mill’s proposal. Moreover, reflection on the alternative plural voting scheme disrupts our intuitions about what counts as an egalitarian voting system. Undue emphasis on Mill’s version of plural voting obscures three important reasons to reject plural voting in favor of strictly egalitarian voting systems: (1) that certain choices that generate inequalities of political power are morally impermissible; (2) that even chosen inequalities may undermine the potential epistemic benefits of democratic decision-making; and (3) that such choices may undermine citizens’ commitments to democracy understood as a joint project
