We argue that a reinvention of the plebeian tribunate should play a key role in addressing the challenges stemming from increasing concentrations of, and inequalities in, social, political, economic, and cultural power in liberal democracies. Addressing these challenges, which negatively affect parliamentary representation, requires a form of institutional innovation that gives voice to non-elites who are ruled but do not rule. We propose revisions of the composition and tasks of the tribunate that are tailored to these current challenges. Our fully (...) randomly selected tribunate emerges as a vehicle not only for contesting concentrated power but also for articulating lines of conflict, disruptive agenda-setting, and political experimentation. Our proposal contributes to developing realist democratic theory. We argue that the reinvented tribunate not only meets realist commitments to avoiding moralization and idealization but also demonstrates the underexploited capacity of realism to inform institutional innovation and thus contribute to substantial political analysis.
