Electoral system for the president
Argentina
Mark P. Jones, Martín Lauga and Marta León-Roesch, “Argentina,” in Elections in the Americas: A Data Handbook, vol. 1, South America, ed. Dieter Nohlen (Oxford: Oxford University Press, 2005), 62-64.
The Constitution of 1853 was reinstated after the fall of the dictatorship, and despite some adjustments between 1983 and the major reforms of 1994, important elements of the original document were preserved until 1994, including the six-year presidential term and the prohibition of immediate reelection to successive terms. Further, “Presidential elections were indirect, via an electoral college, which was formed by a number of electors twice the size of the total number of chamber deputies and senators. An absolute majority in the electoral college was required. If no candidate attained such a majority, the Argentine congress would choose from the two candidates who had received the most votes in the electoral college.”
Note: 1993 was only a parliamentary election year.
