This article draws on the assumption that certain congruence between the parties' electoral
platforms and of the succeeding government's performance shall exist in democratic
systems and shall, as such, be considered as an important research topic for the researchers
of democratic policy-making processes and political systems in general. In the
article, we analyse whether the contents of parties' electoral programmes and the contents
of key post-electoral governmental policy documents e that is, the coalition agreement,
the government sessions' agenda and governmental weekly press releases ecorrespond to
each other. Slovenia, as one of the younger EU democracies, is used as a case study to test
the application of the stated. Original Manifesto Research on Political Representation
(MARPOR) methodology for quantifying documents' content is applied and analysis primarily
focuses on governmental period of the first right-centred government from 2004 to
2008. The conclusions confirm the existence of issue congruence in the period of the
analysed electoral cycle, and at the same time reveal substantial specifics between the
hierarchy of political to policy issue orientations of the government and its constitutive
political parties. Consequently, an initiative for constructing a tentative theory of political
documents is put forward on the basis of inductive research conclusions
