In a democracy, citizens are expected to have political opinions. Previous research has shown that citizens, in part, form their opinions by following cues from political parties. Building on this literature, this article argues that these cueing effects are the result of individuals identifying with political parties, leading to parties as credible sources and alignment of attitudes to maintain in-group coherence (motivated reasoning). However, party cues can only be successful when individuals are actually exposed to these cues, which previous research has not explicitly studied. Using survey data (N = 20,893) collected from 21 EU member states, this study shows that cueing effects indeed depend on the strength of party identification and the degree of exposure. These results demonstrate the contingent nature of party cueing effects which are also changing as party loyalties decrease.KEYWORDS public opinion; party cues; identities; political behaviour; quantitative survey An important aspect of democracy is citizens forming opinions in a meaningful way. But how do citizens form their opinions? Already some 50 years ago Converse (1964) argued that the majority of citizens do not have a clear set of beliefs that result in consistent and meaningful opinions. Based on Converse's ideas, Zaller (1992) suggested that citizens' opinions are formed through exposure to elite discourse. He argued that individuals who are persuaded by elite discourse are those that are likely to both receive and accept the message. Whether a message is accepted depends on whether the information flow is either one-sided or two-sided, but also on which party the information comes from. Several other scholars have observed how these party cues indeed affect CONTACT rachid azrout r.azrout@uva.nl supplemental data for this article can be accessed here: https://doi
