Populist agenda-setting
本文整合多学科文献，从信息、信使、媒介和环境四个维度，理论化民粹主义者在不同政治地位下如何通过话语构建不满，影响政策叙事、辩论框架和媒体使用，从而颠覆主流或夺取权力。
Populist agenda-setting is under-theorized, in part because of the fragmentation of scholarship on populism and agenda-setting. Policy studies has concentrated on the ideas, agents, and mechanisms of mainstream agenda-setting; comparative political economy, political sociology, comparative politics have centred on the sources of populism; and party politics, social movement, and political communication studies have focused on the characteristics of the populists themselves. This article builds on all such literatures to theorise the interactive effects of populism on agenda setting when populists are on the outside, in elective office, or in government. Using the four ‘Ms’ of populists’ ‘discursive construction of discontent’ – message, messenger, medium, and milieu – the article examines how populist messages shape the policy narrative; how populist messengers frame the debate; how they use the media to captivate ‘the people;’ and why, depending on milieu, populists are able to leverage ‘the people’s’ support to upend the mainstream and/or capture power.
