Paying for ads or getting into the news? How parties persuade citizens of their issue competence during an election campaign.

Abstract

During campaigns, parties must defend their reputation of competence on issues to persuade citizens to vote for them (issue ownership). Consequently, what are the most effective strategies to achieve this? I argue that direct (advertising) and indirect (media coverage) communication strategies have different effects on citizens' perception of party competence. To analyze the impact of campaign dynamics on citizens, I use three data sources: an individual rolling cross-section panel, a media coverage analysis, and a parties' advertisements analysis. I link those data on a daily basis to capture the dynamics of parties' communication and citizens' opinion. The results show that advertisements help parties to win and maintain their issue ownership, while media coverage only helps parties to maintain their ownership. The study has scientific and practical implications with regard to party strategy, campaigns, and citizens' perceptions of parties.
