Few questions have triggered as much theoretical debate and empirical research in the field of political communication as the potential impact of communication on voting behavior. This entry discusses the theoretical underpinnings, main empirical results, and future research perspectives regarding the influence of communication by political actors, communication by journalists, and interpersonal communication on two forms of voting behavior: voter turnout and vote choice. Despite fears to the contrary, communication about an election will encourage citizens to participate and cast their votes. At the same time, the influence of communication on vote choice seems to occur mainly in the form of indirect effects, such as knowledge gains, agenda-setting, and priming and framing effects. A direct persuasive influence is comparatively rare and mostly short-lived. But this may change as the proportion of undecided, more susceptible voters continues to rise in many countries.
