This study examines the possible effect of the president's vote totals in states on Presidents Carter's and Reagan's support among senators. Using senators' Congressional Quarterly (CQ) presidential support scores as the dependent variable, this paper hypothesizes that Carter and Reagan's support is significantly and positively related to their electoral success in that Senator's state for the years 1977 through 1988. Several control variables are included to help explain support. There is qualified corroboration for the hypothesis that senator's presidential support scores are significantly and positively related to the president's electoral success for specific administrations and for specific-party senators, although not for the original hypothesis that aggregated the period 1977 to 1988.

Studies of political parties in Latin America have often been descriptive and not directed to link a theoretical foundation about political parties with qualitative or quantitative empiricism. This was in part because parties in the region were usually perceived as rather unimportant in the political arena. This study attempts to correct this often unjustified proposition by focusing on the development of political parties in five Central American countries: Costa Rica, Nicaragua, El Salvador, Guatemala, and Honduras. The analysis focuses particularly on the relationship between party fragmentation, party polarization, the level of democracy, and socio-economic modernization. The quantitative analysis uses a cross-national longitudinal research design and tries to overcome shortcomings in prior descriptive approaches based on case studies. The overall findings show that party fragmentation and party polarization are positively related to the level of democracy in Central America.

Since its creation in 1875, the Canadian Supreme Court has undergone several institutional transitions. These transitions have changed the role of the Court toward a more explicit and influential policy making role in the country. Despite this increasingly significant role, very limited attention has been given to the Court. With this perspective in mind, this study presents several analyses on the decision making process of the Canadian Supreme Court. At the institutional level, the study found that within the stable workload, the cases composition has shifted away from private law to public law cases. This shift is more significant when one concentrates on appeals involving constitutional and rights cases. The study found that this changing pattern of the Court's decision making was a result of the institutional changes shaping the Supreme Court. Statistically, the abolition of rights to appeal in civil cases in 1975 was found to be the most important source of the workload change.
