MOREIRA, Constanza. Party systems, political alternation and ideology in the south cone (Argentina, Brazil, Chile and Uruguay).Translated byRafael Piñeiro. Rev.urug.cienc.polít. [online]. 2006, vol.2Selected edition. ISSN 0797-9789.

The aim of this article is to analyze the alternation of political parties in government, which has taken place in Argentina, Brazil, Chile and Uruguay since the democratic transition and until now. This paper takes into account the hypotheses that link changes in party systems with the dynamic of ideological competition among them. This paper is also aimed at shedding light on the impact of the government processes on the ideological dynamics of the party system, particularly, the impact produced on the polarization level of the system since leftist ideological parties came to power.

Keywords : Democracy; Political Parties; Latin America.
