This article tackles the particular issue of split-ticket voting, which has been largely overlooked in Belgian election studies thus far. We contribute to the literature by answering two particular research questions: (1) to what extent and (2) why do voters cast a different vote in the elections for the provincial council as compared to their vote in the elections for the municipal council?
The article draws on survey data collected via an exit poll in the ‘Belgian Local Elections Study’, a research project conducted by an inter-university team of scholars.
Our analysis shows that nearly 45% of the total research population cast a split-ticket vote in the local elections of 2018. However, this number drops to one out of four if we only consider a homogenous party landscape at both levels by excluding the numerous votes for ‘local’ lists (which occur mostly at the municipal level). This finding underlines the importance of accounting for the electoral and institutional context of the different electoral arenas in research on split-ticket voting in PR systems. In the Belgian context, split-ticket voting in 2018 also differed between the different parties and regions. Furthermore, it was encouraged by a higher level of education and familiarity with particular candidates. This candidate-centred and strategic voting was matched by party identification and the urban municipal context favouring straight-ticket voting. Other factors such as region, a rural municipal context and preferential voting seemed more relevant to determine voting for local parties than using the instrument of split-ticket votes as such.

Belgium has long been described as a typical case of a consociational or consensus democracy. This article aims at identifying whether political parties in Belgium share the internal characteristics of parties in consensus democracies: passive mass memberships, the importance of purposive and material incentives for joining, and representation of a clear subculture in the social and attitudinal profiles of their members and via overlapping memberships with related organizations. We mobilize longitudinal party membership data and party member surveys conducted in three different time periods. We show that pillar parties still exercise their role of mobilization and representation of societal segments, but these segments tend to become smaller over time. New parties offer alternative options of mobilization and representation, although not always in line with the specific institutional arrangements of consociational democracy.
