Emotions matter in politics – enthusiastic supporters return politicians to office, angry citizens march in the streets, a fearful public demands protection from the government. Anxious Politics explores the emotional life of politics, with particular emphasis on how political anxieties affect public life. When the world is scary, when politics is passionate, when the citizenry is anxious, does this politics resemble politics under more serene conditions? If politicians use threatening appeals to persuade citizens, how does the public respond? Anxious Politics argues that political anxiety triggers engagement in politics in ways that are potentially both promising and damaging for democracy. Using four substantive policy areas (public health, immigration, terrorism, and climate change), the book demonstrates that anxiety affects how we consume political news, who we trust, and what politics we support. Anxiety about politics triggers coping strategies in the political world, and these strategies are often shaped by partisan agendas.
