List proportional representation with candidate voting can facilitate policy representation in multiple dimensions. However, candidates with deviating positions may not benefit if cues such as shared socio-demographics drive candidate choice instead. Does this use of cues reflect a lack of policy-related information or a preference for descriptive representation? We study this question in a real-world context, using a survey-embedded experiment that emulates actual vote choice shortly after the 2019 Swiss elections. We vary the level of information on candidates' policy positions in zero, one or two dimensions (left–right, environment). Our results show that spatial proximity voting increases with better information on the secondary (but not the first) dimension, indicating that information can improve the alignment of (environmental) policy views between voters and candidates. In turn, same-gender and same-age voting slightly decreases when more information is available. The preference for local candidates remains strong. Our results inform debates regarding citizens' preferences for different types of representation and how electoral systems moderate their expression.
