For many international experts, politicians, and commentators, Denmark stands out as an ideal society with a well-functioning welfare state, low levels of corruption, and a high degree of social and political stability. Like other countries, however, Denmark faces challenges brought on by overall societal changes—particularly the challenges of maintaining a prosperous economy and from the growing number of immigrants with different ethnic and religious backgrounds that have left their mark on Danish society over the past 50 years. But how have Danish voters reacted to these challenges? The authors of The Danish Voter investigate a series of interesting questions concerning voters’ reactions to these macrosocial challenges and how their reactions affect the foundations for the ideal. Indeed, due to an electoral system open to new influences, the Danish case is an important test case for theories about political development of contemporary Western societies.
