• 1. Introduction and theoretical framework Silja Häusermann and Herbert Kitschelt; Part I. Voter Flows and Electoral Potentials: 2. The changing geography of the social democratic vote Jane Gingrich; 3. Losing the middle ground: the electoral decline of social democratic parties since 2000 Tarik Abou-Chadi and Markus Wagner; 4. Who continues to vote for the left? Social class of origin, intergenerational mobility and party choice in Western Europe Macarena Ares and Mathilde M. van Ditmars; 5. Lost in transition: Where are all the social democrats today? Daniel Bischof and Thomas Kurer; 6. Social democracy in competition: voting propensities, electoral potentials and overlaps Silja Häusermann; Part II. Considerations of Choice: Motivations and Preferences: 7. Vote switchers and social democracy in contemporary knowledge capitalism: voter rationales signal strategic dilemmas of social democracy Herbert Kitschelt and Philipp Rehm; 8. Labor unionization and social democratic parties Silja Häusermann, Herbert Kitschelt, Nadja Mosimann and Philipp Rehm; 9. Old left, new left, centrist or left national? Determinants of support for different social democratic programmatic strategies Tarik Abou-Chadi, Silja Häusermann, Reto Mitteregger, Nadja Mosimann and Markus Wagner; Part III. Determinants of Electoral Outcomes for Social Democratic Parties and the Left: 10. Voter responses to social democratic ideological moderation after the third way Jonathan Polk and Johannes Karreth; 11. Social democracy and party competition: Mapping the electoral payoffs of strategic interaction Herbert Kitschelt and Philipp Rehm; 12 The electoral consequences of centrist policies: fiscal consolidations and the fate of social democratic parties Björn Bremer; 13. Leadership turnovers and their electoral consequences: a social democratic exceptionalism? Zeynep Somer-Topcu and Daniel Weitzel; 14. Conclusions Silja Häusermann and Herbert Kitschelt.

'Beyond Social Democracy will be the reference for anyone studying social democracy and party system change in established democracies in the coming years. The introduction sets the stage with a brilliant theory of the temporalities of the transformation of the left; the different empirical chapters make use of different types of data and estimation strategies to provide evidence of the strategic dilemma that social democratic parties are in; and the result is an edited volume that is exceptionally coherent, theoretically ground-breaking and empirically extremely well conducted.'
