The changes occurred in the Colombian political system during the time between 1974 until 2006, referred to as the variation of rules and incentives contained in the voting system, brought along the change of the status quo in the two-party dynamics. The flexibility in the participation channels and the change of inducement would have speeded up the factionalization of the traditional parties, which is understood as the internal division process of a political collectivity into subgroups, which care on finding their own satisfaction through the consecution of selective incentives over the welfare of the group that keeps them together. Therefore, comparatively valuing the two-party system evolution, specifically centered in the liberal party from the local aspect, taking as a study case the coffee-region, focused in the capital cities Armenia, Manizales and Pereira, towards the national perspective, allows one to add description-elements and the analysis in the investigations towards voting regionalization of the country. Though, it is necessary to explain that the study generates a hypothesis according to which the independent adjective obtained by some new local political movements, should be used with precaution as they might be only nominal manifestations of the two traditional parties.
