To what extent have political decision-making processes become mediatized? Based on this question- the author analyzes media coverage and parliamentary actors’ (MPs) strategies and perceptions in three conflicted decision-making processes in Switzerland. Mediatization of politics refers to behavioral changes and adaptations of political actors- institutions- and processes that are related to (mass) media. According to some scholars- mediatization may lead to politics of immediacy- conflict- drama- and personalization- thereby challenging established institutions and processes in liberal democracies. The quantitative and qualitative analyses of MPs’ strategies and perceptions provide new insights into how political actors may “self-mediatize” in the advent of globalization and polarization. Overall- the book adopts an actor-centric approach and shows that mediatization of politics is not a fate- but a strategic choice.
