An ongoing debate concerns the extent to which political consumerism constitutes political behavior. To address this debate, researchers have examined several predictors of political consumerism, but have not focused on its communicative dimensions, especially with respect to digital media. In this study we conceptualize political consumerism as a form of civic engagement, and we theorize that people who use social media are more likely to engage in political consumerism than those who do not. Using original survey data collected in the US, we find that political consumerism is more closely related to civic engagement than it is to political participation, and that use of social media mediates the relationship between general Internet use and political consumerism.
