The religious and spiritual underpinnings of party choice in christian Europe

•Spirituality is related to a higher likelihood of voting for Green parties.•Religiosity fosters the preference for Green parties over Social Democratic parties.•Green parties do not have an exclusively secular electorate.

Many studies have shown that individual religiosity is related to a Christian Democratic vote. Recently, studies from sociology of religion have reported the rise of holistic spirituality. This paper is the first to examine the effects of holistic spirituality on party choice. In addition, it critically assesses the assertion that conventional religiosity prevents individuals from affiliating with Green parties.Our results show that spirituality is related to a higher probability of choosing Green parties. Moreover, conventional religiosity increases the probability that moderate left voters will prefer a Green party to a Social Democratic party. This result shows that there is common ground between the electorates of Green and Christian Democratic parties, thus creating possibilities for new political coalitions.
