The question of how the American political process shapes inequality remains unsettled. While recent studies break ground by linking inequality to political institutions, much of this work focuses on national-level income inequality. The literature is lacking in its examination of inequality in other issue areas at the subnational level. This research explores how partisanship in government affects subnational-level inequality in health care coverage in the context of racial diversity. Using a new Gini-coefficient measure of inequality in health insurance coverage, we find a negative relationship between the seat share of Democratic representatives and inequality in health care coverage but only in states with racially diverse populations. Moreover, Democratic-controlled state legislatures mitigate the negative impact of racial diversity on inequality in health care coverage. These results highlight the importance of examining the partisan foundation of health care inequality in the context of racial diversity.

Two very different kinds of models—cross-sectional models based on the logic of island biogeography and time series models of density dependence—are used to understand interest system density. While they share much in common, it is not at all clear how results derived from cross-sectional models are to be understood in terms of the temporal focus of the time series approach. Thus, the first purpose of this article is to more thoroughly think through how these two modeling strategies and their empirical findings are related to each other. We empirically assess several theoretical conjectures about the relationship of the two modeling strategies by adding a temporal element to the typical cross-sectional analysis of state interest systems via modeling density dependence pooled across four cross-sections from 1980, 1990, 1997, and 2007. By doing so, we add to the literature on state interest system density by examining how it has changed since 1980. Finally, we discuss the nature of this change and what it implies for the temporal development of state interest communities, the second focus of this analysis.

Little is known about the role of Spanish-language media in the representation of Latino constituencies in statehouses. In this article, I present analyses of elite-level data from the Media and Public Policy in the States: 2011 Survey, which reveal state legislators' attitudes and orientations toward the news media. Building on the view that Spanish-language media provide an important representational link between Hispanic constituents and their political representatives, I argue that the level of media sophistication or “media entrepreneurship” state legislators bring to their representative role is a function of legislators' Spanish media environments. Through statistical tests of the relationships between the Spanish-language media environment, state lawmakers' perceptions of the media's effectiveness, and their use of media tools, I find evidence that district-level Spanish-language media contexts influence lawmakers' level of engagement with the news media.
