This chapter looks at the changing nature of ideology in Europe. It also delves into the issue of voter preference and considers how that has changed over time. It is all too often assumed that voters, as well as parties, exist along a single ideological left-to-right continuum. However, the truth is that there more deviations from this continuum than we might have in the past assumed. With the emergence of new salient issues, such as immigration, the environment and European integration, the old assumptions no longer hold true. The chapter also looks at populism, which it defines as a thin-central ideology. The final questions of this chapter are: how has populism challenged our current model of democracy? What does the future hold in this regard?
