Abstract“Lifestyle politics” suggests that political and ideological opinions are strongly connected to our consumption choices, music and food taste, cultural preferences, and other aspects of our daily lives. With the growing political polarization this idea has become all the more relevant to a wide range of social scientists. Empirical research in this domain, however, is confronted with an impractical challenge; this type of detailed information on people’s lifestyle is very difficult to operationalize, and extremely time consuming and costly to query in a survey. A potential valuable alternative data source to capture these values and lifestyle choices is social media data. In this study, we explore the value of Facebook “like” data to complement traditional survey data to study lifestyle politics. We collect a unique dataset of Facebook likes and survey data of more than 6500 participants in Belgium, a fragmented multi-party system. Based on both types of data, we infer the political and ideological preference of our respondents. The results indicate that non-political Facebook likes are indicative of political preference and are useful to describe voters in terms of common interests, cultural preferences, and lifestyle features. This shows that social media data can be a valuable complement to traditional survey data to study lifestyle politics.

Preference votes constitute one of the key features of (open and flexible) PR-list electoral systems. In this article, we give an extensive overview of studies conducted on preference voting in Belgium and the Netherlands. After elaborating on the definition and delineation of preference voting, we scrutinize studies about which voters cast preference votes (demand side) and about which candidates obtain preference votes (supply side). For each of these aspects, both theoretical approaches and empirical results are discussed and compared. At the same time, we also pay attention to methodological issues in these kinds of studies. As such, this research overview reads as an ideal introduction to this topic which has repercussions on many other subfields of political science.

Recent research demonstrates that whereas political parties in Western Europe are generally structured along one dimension -and often take more or less similar ideological positions on the economic and cultural dimension -the policy preferences of voters are structured two-dimensionally; a considerable part of the electorate combines left-wing stances on one dimension with right-wing stances on the other. These ideologically 'unserved' voters are the main focus of this study. Using data from a large-scale survey in Flanders and Wallonia, we demonstrate how the salience of the two dimensions explains whether these unserved voters ultimately end up voting for a right-wing or a leftwing party. Specifically, we show that these voters elect a party that is ideologically closest on the dimension that they deem most important at that time. All by all, the findings of this study confirm that salience is a key driver of electoral choice, especially for cross-pressured voters.
