The shifting class-base of social democratic parties in Western Europe

Abstract

ABSTRACT In a classic piece, Przeworski and Sprague describe an electoral dilemma of social democratic parties: they need to attract middle-class voters without losing support in the shrinking working-class. With cultural issues (e.g. immigration) becoming more salient, this dilemma has intensified recently as the positions of both classes differ markedly on those issues. Against this background, we analyse the class base of social democratic parties in 13 Western European countries using data from the European Social Survey (2002–2018). Our exploratory study shows that in almost all countries support for social democrats has decreased across all classes. Yet, we still find significant differences in the social democrats’ class bases. In Denmark, Sweden or Spain, social democrats still largely base their support on service and particularly production workers, while in France or Switzerland, these groups no longer primarily vote for social democrats. Here middle-class people, particularly socio-cultural professionals, are the strongest supporters of social democrats. Countries such as Germany or Norway exhibit no clear social democratic class base and gaining support from both groups at the same time seems to be most difficult. Only the British Labour Party succeeded to some extent in the balancing act of winning both middle- and working-class voters.
