This study examines how political cynicism and social media communications moderate the spillover effects of political scandals, that is, the extent to which a scandal surrounding one political figure may influence people’s attitudes toward other political objects. Theoretically, spillover effects are understood as grounded in how people understand the interconnections among politicians and institutions. Analysis of a representative survey in Hong Kong documents the presence of spillover effects of scandals surrounding the Chief Executive of the government. The findings also illustrate the moderating role of political cynicism and, to a lesser extent, political communications via social media.
