In a merciful twist of fate, Juan Linz did not quite live to see his prophecy of the demise of American democracy borne out. Linz, the Spanish political scientist who died last week, argued that the presidential system, with its separate elections for legislature and chief executive, was inherently unstable. In a famous 1990 essay, Linz observed, “All such systems are based on dual democratic legitimacy: No democratic principle exists to resolve disputes between the executive and the legislature about which of the two actually represents the will of the people.” Presidential systems veered ultimately toward collapse everywhere they were tried, as legislators and executives vied for supremacy. There was only one notable exception: the United States of America.
