Ley de Lemas


Ley de Lemas is the Spanish name of the double simultaneous voting electoral system which is, or has been, used in elections in Argentina, Uruguay, and Honduras. It employs an unusual open party-list proportional representation system, and works as follows:
The Lemas system was designed in 1870 by the Belgian professor Charles Borelli.

Uruguay

Lemas were introduced in Uruguay in the early 20th century when the "Lema law" introduced double simultaneous voting. It allowed for the election of the President, Chamber of Deputies and Senate by casting a single vote. Parties acted as lemas, while party factions formed sublemas. Voters would vote for a sublema of a party, with the totals of sublemas totalled to establish the winning party.
During periods in which a presidential system was enacted, the presidential candidate of the sublema in the winning party with the most votes would become President.
This system was abolished for presidential elections after constitutional reforms were passed in a 1996 referendum, restricting each party to a single presidential candidate. Department elections still use the old system.
The parliamentary and department elections still use double simultaneous voting.

Honduras

applied the Ley de Lemas in the 1985 presidential election, when, due to factionalism within the two dominant parties, both were unable to elect a single presidential candidate.

Argentina

In Argentina, a number of provinces employ or have employed a version of this electoral system.
Currently, this law is in the provinces of Formosa, Misiones and Santa Cruz. Provinces have complete freedom to elect local and national representatives using the method of their choice; the system propagates down to the municipal level.
The lemas system has never been used in Argentina for a presidential election, though the idea was circulated before the 2003 election. In the wake of Fernando de la Rúa's resignation in the wake of the 2001 riots, original plans called for a permanent successor to be elected in 2002 under the lemas system.

Support

The Ley de Lemas presents itself as a solution to the problem of fiat selection of candidates performed behind closed doors by party factions. By allowing many candidates to run within the same party and leaving the decision to the citizenry, the system is supposed to end the practice of dark intra-party alliances and add transparency to the conflicts between internal factions. This helps the participation of independent candidates without support from powerful party figures. It also avoids primary elections.

Criticism

The party-list proportional representation system works under the assumption that the citizens vote primarily for parties. However, citizens often place emphasis on individual candidates rather than the parties' perceived ideological platforms. The diversity of views allowed within a single party means that voters may end up indirectly giving their vote to a candidate that the voters do not really support. A party that decides to present multiple candidates, either with similar or opposing ideologies, may win even if the elected candidate had few votes compared with all the other candidates. For example, in the 1971 Uruguayan presidential election, Juan Maria Bordaberry won the presidency despite finishing over 60,000 votes behind Wilson Ferreira Aldunate. However, in that election, candidates from Bordaberry's Colorado Party won 12,000 more votes between them than the candidates from Aldunate's National Party.
Also, proportional representation system are intended for multiple winnersfor example, candidates to fill a legislative chamberbut the Ley de Lemas has been used to elect single winners.
