In this paper, the speaker argues that the mobilization of substate identities has profound implications for both comprehensive measures of ideology and particular preferences for redistribution. Focusing on Spain, a high-capacity, modern state distinguished by the variety and intensity of the substate identities found within its borders, she finds that for strong identifiers with mobilized substate identities, policy scope, the political community in which a policy is intended to apply and be carried out, is nearly as important as policy content, the actual intended effects of a policy. Her empirical analysis proceeds in two steps. First, she investigates the structure of policy preferences in Spain by estimating latent differences in multidimensional ideological preferences across regions. Second, she identifies the mechanisms connecting substate identity to preferences for policy scope using the results of an original survey she conducted in Spain in June 2017. The results of an experiment embedded in the survey reveal that strong identifiers are more likely to support redistribution when its scope is the community with which they most identify. Moreover, the importance of scope is not merely due to the familiar mechanism of in-group/out-group bias. The importance of scope also stems from differential trust in political elites, such that shared identity between respondents and elites increases support for redistribution.
