In the former communist countries of SEE is still difficult to make the identification and classification of political parties under the political spectrum. "Left" and "right" have almost identical political attitudes and electoral programs. The differences are minimal. The important component on ideological divisions are regional divisions, religious, ethnics, populist offers, interest groups that rely on specific names of political leaders, etc. I'm interested in similar studies and analysis in other countries as for example, studies from Latin America, the former Soviet republics, etc. - which are the factors that determine the ideological divisions of political parties and political behavior indicators of parties themselves?
