Political representation is challenged by social acceleration, the rise of populism, and electoral volatility. Politicians’ need for prioritizing time and energy is acute and consequential for democracy. Voters’ preferences constitute one democratically relevant standard for guiding such priorities. However, current research mainly focuses on voters’ preferences for representatives’ personality traits or policy outcomes, which are hard for an individual politician to control. This study provides a conceptual framework for analyzing politicians’ task priority by separating functional legislative tasks from relational representative tasks, and employs this framework in surveys among Danish, German, UK, and US voters. Analyses of open-ended answers, time allocations, and conjoint experiments show that voters assign higher importance to functional tasks compared to relational tasks. The framework offers a new approach to studying political representation in practice, and the results provide guidance for how politicians should prioritize scarce resources for political representation in a high-speed, volatile political context.
