Introduction and Theoretical Framework
This chapter provides an analytical framework for the empirical studies comprised in the volume. It starts by defining the relevant temporalities to study party strategies and sociostructural processes of electoral realignment. The chapter then develops the concept of the “social democratic idea” that underlies the entire left field of political parties. The third section defines four key structural challenges to the social democratic idea and the potential responses and trade-offs resulting from them for the left field. The fourth section discusses party strategic alternatives to respond to structural challenges and transformations of the social democratic electorate and then differentiates this discussion by different contexts characterized by political-economic legacies and institutions. The chapter concludes with an outline of the book.
