Leaving the Space - Opening the Gap? Electoral Effects of Parties' and Voters' Repositioning

Examining the German case in the wider Western European context for the period 1996-2017, the chapter investigates the role of supply and demand factors for vote switching in general and switching to right-wing populist parties in particular. Combining survey data from the CSES with party data from the Manifesto Project, the chapter shows that the growing success of right-wing populist parties, in Germany just as in other Western European countries, was a response to programmatic moves of mainstream center-left and center-right parties to the left. In general, voters’ movements between parties did not follow a symmetric pattern. Changes to parties further left came about as responses to increasing voter-party distances on the socio-economic dimension. In the more recent past, switches to parties further right and, in particular, right-wing populist parties like the German AfD became more frequent, and they were associated with increasing distances on the socio-cultural dimension.
