Este trabajo busca analizar algunos puntos de la Reforma Politica y del Referendo, llevados a cabo durante el primer Gobierno de Alvaro Uribe Velez, para asi determinar cual era la intencion de estos cuando fueron escritos y cuales podrian ser los cambios que producirian en el sistema de partidos en caso de ser aplicados a la realidad, en particular en cuanto a la financiacion de las campanas y el papel del Estado, la democratizacion interna y el trabajo en bancadas. Del Referendo se estudiaran tres puntos que hacen referencia directa al sistema de partidos como lo son el 2, el 6 y el 15, los cuales tratan el voto nominal, la reduccion del Congreso, el umbral y la cifra repartidora, y la reforma al sistema electoral respectivamente. This article analyzes some of the features of the Political Reform Act and the Referendum that took place during President Alvaro Uribe’s first term in office. This is done with the purpose of showing what the intention was behind these acts when they were drafted, and what would their effect have been on political parties in Colombia had they been implemented, particularly with regard to campaign finance, the role of the State, internal democratization, and work done in coalitions. The author studies three sections of the Referendum that point directly to the party system; these are sections 2, 6, and 15, which refer to public voting, the reduction of Congress, the threshold and the highest averages method of voting, and the reform of the electoral system.
