Dutch elections continue to be the most volatile of Western Europe. But to what extent do voters’ changes in vote intentions continue to be structured by underlying ideological dimensions? This article discusses various theories on the ideological structure of the Dutch party system at the electoral level, and the way they relate to processes of dealignment and realignment. We test these theories using the 1Vandaag Opinion Panel data set, which follows 54 763 respondents in 53 waves between November 2006 and June 2010. We assess individuals’ changes in vote intentions, and analyse the structure in these changes. We draw three conclusions. First, Dutch voters are boundedly volatile and they tend to stick to one of two blocks of parties: a block of traditionally left-wing parties (PvdA, SP, GL) and a block of right-wing parties (CDA, VVD, TON and PVV). D66 functions as the electoral lynchpin between these blocks. Second, the Dutch party system is best described by a sociocultural dimension and a socio-economic dimension. Third, there is support for realignment (along the sociocultural dimension) and continued alignment (along the socio-economic dimension). Yet, we find evidence for widening electoral divisions: there is an electoral gap in the traditionally crowded political centre.
