What are the most challenging ethical dilemmas for politicians, and how do they handle them? The classical literature on ethical dilemmas in politics has mainly explored them as conflicts between ethical principles in high-stakes decisions. However, empirical evidence of the extent to which such dilemmas accurately reflect the experience of most politicians is scarce. Drawing on extensive in-depth interviews with Swedish parliamentarians, I show that their dilemmas stem mainly from powerlessness. Powerlessness in politics manifests itself in primarily two ways: relational powerlessness, which is driven by constraints like party and constituency loyalties, and inherent powerlessness due to formal and informal barriers like constitutional mandates and limited time and resources. This study contributes to the field of political ethics by anchoring political dilemmas in everyday democratic politics and by introducing powerlessness as a new central concept. In doing so, it supplements our understanding of ethical dilemmas in politics with insights from those confronting them.
