People decide about political parties by taking into accountthe preferences, values, expectations, and perceptions of theirfamily, friends, colleagues, and neighbours. As most people livewith others, members of their households influence each other'spolitical decisions. How and what they think about politics andwhat they do are the outcomes of social processes. Applying variedstatistical models to data from extensive German and Britishhousehold surveys, this book shows that wives and husbandsinfluence each other; young adults influence their parents,especially their mothers. Wives and mothers sit at the centre ofhouseholds: their partisanship influences the partisanship ofeveryone else, and the others affect them. Politics in householdsinteracts with competition among the political parties to sustainbounded partisanship. People ignore one of the major parties andvary their preference of its major rival over time. Electioncampaigns reinforce these choices.
