The article discusses the difficulties of political reforming in the countries of Eastern Europe in the postsocialist period. It is emphasized that during the transition period new governments made serious political mistakes. New political elite and political parties of the East European countries failed completely to solve a number of difficult political problems. Among them the author mentions: the imperfection of the parties and party systems, inadequate role of the political parties in the development of the civil society; negative phenomena in the interaction of multiparty democracy and election campaigns; discrepancies between the electorate’s sympathies and the membership of parliaments; the existence of "fictitious” and "non-liberal” parliamentarism; the violation of the democratic pluralism principle and the lack of tolerance; the arrogant attitude of the political elite and governments to the citizens; the suspension of a certain part of the society from participation in the political process; and lustration.
