Media Bias,Public Opinion,and Policy Liberalism from 1956 to 2004: A Second-Level Agenda-Setting Study

This study aims to explore second-level agenda-setting at the national level. In particular, it examines the relationships among the citation bias of the New York Times, national level public opinion, and Congressional policies from 1956 to 2004 in order to better understand mass media's role in national policymaking. In addition, it also tests one important intervening variable of the relationships among the three attribute agendas (the media agenda, the public agenda, and the policy agenda)—the president's policy liberalism.
