Episode 13:.The Ripple Effect—How Radical Right Success Shifts Mainstream Politics

Ever wondered how radical right parties influence mainstream political landscapes? In this episode, we unpack Tarik Abou-Chadi and Werner Krause's insightful research on how radical right successes drive mainstream parties to adopt tougher positions on immigration and cultural protectionism.

Using design-based quantitative techniques, the authors reveal a clear causal relationship: when radical right parties achieve parliamentary representation, mainstream left and right parties significantly shift toward more restrictive immigration policies. Are these shifts strategic adaptations or genuine ideological changes?
