Does partisanship echo across household lines? This article examines how shared political identity influences electoral participation through relational selective consumption benefits. Using British household survey data, it provides empirical evidence that when individuals align with other family members' partisan loyalties, their likelihood to vote increases significantly.

Beyond personal beliefs, the civic norms learned within one's household also shape voting behavior. The study isolates these effects by accounting for individual civic duty levels. Results indicate that both shared partisanship and inherited household civic norms predict higher turnout rates, even after controlling for personal inclinations toward civic engagement.

Key findings reveal two distinct pathways: expressive alignment with family members boosts turnout directly through relational selective consumption benefits; simultaneously, the presence of strong civic duty norms within households indirectly reinforces voting participation. These insights extend political science theories by demonstrating how household dynamics mediate electoral behavior in ways previously unexplored.
