Abstract

Religion has long been considered an important determinant of voting behaviour. However, the secularisation of Western societies has changed its role. Secularisation not only limits the political relevance of religion, it may also affect the nature of religious cleavages themselves. While extant literature suggests that differences between religious denominations are in decline, with regard to differences between religious and non-religious voters there are two divergent expectations, (1) that these differences are also in decline and (2) that there is an increased polarisation between the religious and the non-religious. For the latter expectation, evidence has already been found regarding the United States. In this paper, we examine whether a similar change can be observed in Western Europe. Combining data from the European Social Survey (ESS) and information on parties’ positions from the Chapel Hill Expert Survey (CHES), we assess the nature of over-time changes in the connection between religion and the vote choice. The results point to an increased polarisation between members of a Christian church and the non-religious, however, we also find that non-Christians are more similar to the non-religious than to Christians. We also uncover a growing division between Catholics and Protestants that does not fit common expectations. These findings challenge earlier work on the political consequences of secularisation and lead to new research questions.
