Fractures in the Fabric of Democracy? : Change and Continuity in Public Opinion in Contemporary Europe

Is representative democracy in Europe becoming undermined by developments in public opinion? This dissertation addresses this overarching question, by studying the development over time of (i) ideological polarization; (ii) the degree to which vote choices are structured by political attitudes; and (iii) the degree to which parties are internally congruent in political opinion across levels. Public opinion is understood as the metaphorical ‘fabric’ of representative democracy, where conjectures to the fact of a fracturing dynamic are plausible and recurrent in academic and public debate. Thus, this thesis contributes with studies in three particular areas, regarding the interaction between political attitudes and the political system. The studies show that there have not been dramatic ruptures in these aspects of political opinion. Neither polarization, disintegration, nor incongruence are the most appropriate words to characterize developments in general. Some changes are taking place, in particular as attitudes on immigration are becoming more important in all aspects considered. Paper I studies political polarization in a qualified sense, focusing on ideological views among the electorates of European democracies. The paper presents a conceptualization and measurement of ideological polarization that is partly novel, and proceeds to investigate patterns across countries and time. Paper II studies the degree to which vote choices in contemporary European democracies are connected to political views, in particular left-right placements, among electorates in Europe. This degree is gradually declining in most cases, and attitudes on secondary dimensions are generally rising in importance. In particular, the left-right scale is subsuming more issues than before, while issue attitudes are becoming gradually more important for explaining vote choices independently as well. Paper III studies intra-party ideological congruence, focusing on the case of Sweden. Here, the f
