Recent survey experiments show that information on singular policy positions of (fictional) candidates can affect candidate and party choice under open-list PR systems (Blumenau et al. 2017, Bräuninger et al. 2020). This broadens our view on intra-party competition, which has mostly been studied from the perspective of non-policy representation by individual politicians. We investigate whether these findings travel to a setting with real candidates, where voters may have existing preconceptions of candidates and have to balance information on multiple policies. We draw on the context of the Swiss National Parliament election of 2019. In a 2x2-design, we provide survey respondents with ballots of real candidates that vary by information on candidate’s policy stance in zero, one or two policy dimensions. We focus on the two most salient policy fields in this election, and additionally exploit the fact that a large share of the voting population relied on a comprehensive voting advice application that made candidate positioning transparent to voters. This setting allows us to examine whether candidate information under OLPR can actually allow voters to align their own policy preferences with the preferences of candidates, and which factors may prevent such congruence. The setting also allows us to investigate whether parties with higher intra-party variation on one or several policy dimensions can be more attractive to voters under OLPR on aggregate. Our results inform the debate to which extent preference voting may facilitate policy representation by individual candidates; they also speak to the validity of survey-experiments using hypothetical candidates.
