This article is a first attempt to develop and assess the competing predictions of the thermostatic model of public opinion and legitimation theory for the responses of public mood to Supreme Court decisions. While the thermostatic model predicts a negative relationship between the ideological direction of Supreme Court decisions and changes in public mood, legitimation theory predicts that changes in mood should be positively associated with the ideological content of the Court's actions. I assess these rival expectations by modeling the dynamic relationship between mood and cumulative judicial liberalism. The model estimates indicate a complex interaction between the Court and the mass public characterized by short-term backlash against Supreme Court decisions in mood followed by long-run movement toward the ideological positions taken by the Court. The results emphasize the legitimacy of the Court in American politics and point to a unique role for the Court in shaping public opinion. [ABSTRACT FROM AUTHOR]

Formal constitutional systems of separated powers often fail to sustain meaningful systems of checks and balances in presidential-style democracies. What conditions support balance in the separation of powers and what conditions provoke instability and conflict? We draw on Madisonian political theory and research addressing the separation of powers in the United States to develop a game theoretical model of inter-institutional stability and conflict within a separation of powers system. Two factors emerge as catalysts for institutional instability and conflict among the branches of government: high-stakes institutional rivalry combined with uncertainty about the public’s relative support for various branches of government. We apply the model to the experience of Honduras in 2008–2009 that resulted in the coup ousting President Zelaya which illustrates the difficulty of developing credible checks and balances.

Inquiry into the origins of partisan polarization has generally treated polarization as a simple, symmetric phenomenon—the degree to which the worldviews of the mass Democratic and Republican parties have or have not diverged from one another. In this article, we disaggregate polarization into its constituent parts, the dynamic preferences of the mass Democratic and Republican Parties. This approach allows for the possibility that intraparty dynamics may influence interparty differences and for the integration of studies of polarization with literatures addressing other dynamics in aggregate public opinion. Building on individual-level research on partisan identities and macrolevel research on public mood, we argue that party polarization may be catalyzed, in part, by the mass parties’ differential responsiveness to changes in the macro political-economic context. We find support for this position, showing asymmetries in the dynamics of polarization that are associated with differential partisan responsiveness to domestic policy choices.

Scholars often assert that public support for judicial authority induces Congress to grant resources and discretion to the Supreme Court. However, the theory of competing public agency embraced by the Constitution suggests that public support for courts cannot, by itself explain congressional support for judicial authority. Instead, the logic of the separation of powers system indicates that legislative support for the institutional capacity of courts will be a function of public confidence in the legislature as well as evaluations of the judiciary. We test this theory, finding that public confidence in both Congress and the Court significantly affect congressional support for the Supreme Court, controlling for the ideological distance between the Court and Congress as well as the Court's workload. The results offer a more refined and complex view of the role of public sentiment in balancing institutional power in American politics. [ABSTRACT FROM AUTHOR]
