", "\nABSTRACT\nAs political institutions, representative assemblies can be seen as rule‐governed structures of interrelated roles with power mandates, which elected officeholders must exercise in accordance with the normative values justifying the institutions' establishment. One such essential value is collective self‐government, which requires representatives to consider citizens' input. However, partisan disagreement means citizens often have conflicting views on how representatives should act, especially in polarized contexts. This article defends three propositions: (1) trust between citizens and representatives is essential for realizing collective self‐government; (2) for this trust to be justified, representatives must be worthy of it; and (3) partisanship strains citizens' trust in representatives of opposing parties. What I call the partisan predicament illustrates a fundamental issue: representatives inevitably disappoint either their supporters or their non‐supporters. Since trust is critical to collective self‐government, this dilemma can impair the functioning of representative institutions. Although this shows how citizens' autonomy remains a regulative ideal that is never fully achieved, the presence of procedures through which representatives offer justifications for their own interpretation of their commitments and for their compatibility with broader democratic values helps mitigate the negative effects of partisanship.\n"]
