This research revisited how the American public’s political affiliation, prior vote choice, partisan media use and self-assessed economic condition influenced their opinions about former President Bill Clinton’s sex scandal and support for the President’s impeachment. Using the 2000 ANES Pilot Study data, we examined the mediating role of the public’s attribution of responsibility for the scandal to either private or public domain in their support for the presidential impeachment. All independent variables (party ID, prior vote, listening to political talk radio and self-assessed economic condition) had effects on the public’s public-matter attribution. A logistic mediation analysis demonstrated that the public-matter attribution partially mediated the effects of political ID, prior vote, and self-assessed economic condition on support for impeachment. Theoretical and practical implications of the findings are discussed.
