Abstract
The diffusion of presidentialism to Latin America has led to its distortion. The North American constitutional pattern, termed presidentialism under separation of powers and its most distinguishing feature, presidential leadership, while modeled in Latin America, has rarely led to democratic–constitutional government a la the United States. The institution of the presidency in Latin America is also typical for nondemocratic regimes in the region. One of the most widely accepted and widely professed facts in Latin American politics is the dominant role of the president but, curiously, most discussions of presidentialism are limited to the US and comparisons with Great Britain. Few studies of Latin American chief executives lend shape to the corpus of scholarly literature, despite the region's long experience and ejecutivismo. The gap, and this article, should be taken as a stimulus for more systematic explication, analysis, and research.
