How do involuntary interactions with authoritarian institutions shape political engagement? The policy feedback literature suggests that interactions with authoritarian policies undercut political participation. However, research in racial and ethnic politics offers reason to believe that these experiences may increase citizens' engagement. Drawing on group attachment and discrimination research, we argue that mobilization is contingent on individuals' political psychological state. Relative to their counterparts, individuals with a politicized group identity will display higher odds of political engagement when exposed to authoritarian institutions. To evaluate our theory, we draw on the 2016 Collaborative Multiracial Post-Election Study to examine the experiences of Blacks, Latinos, and Asian Americans. For all subgroups and different types of institutions, we find that, for those with a politicized group identity, institutional contact is associated with higher odds of participation. Our research modifies the classic policy feedback framework, which neglects group-based narratives in the calculus of collective action.

Are legislators responsive to the priorities of the public? Research demonstrates a strong correspondence between the issues about which the public cares and the issues addressed by politicians, but conclusive evidence about who leads whom in setting the political agenda has yet to be uncovered. We answer this question with fine-grained temporal analyses of Twitter messages by legislators and the public during the 113th US Congress. After employing an unsupervised method that classifies tweets sent by legislators and citizens into topics, we use vector autoregression models to explore whose priorities more strongly predict the relationship between citizens and politicians. We find that legislators are more likely to follow, than to lead, discussion of public issues, results that hold even after controlling for the agenda-setting effects of the media. We also find, however, that legislators are more likely to be responsive to their supporters than to the general public.
