Although the Constitution of Kazakhstan and Russia established the principle of political pluralism and multiparty legislative regulation itself the status of political parties and the practice of implementing the relevant laws are not conducive to the development of the party system. Unfortunately, in the former totalitarian countries society psychologically very difficult to readjust the values of constitutionalism and democracy. In society, the ruling party, which is led by the incumbent president, in fact identified with the state; other parties play a decorative role and can not really express the views of their supporters. The lack of real political pluralism, inability legal participation of certain social groups, regional elites in government through representation in Parliament, political parties leads to the fact that the constitutional channels Incorporation and expression much of the population are replaced by opaque “shadow” transactions corruption. The institutionalization of corruption at the level of socio- political institution, recognition population corruption standards as the only possible regulator of social relations, the functioning of the state, along with the financial system of illegal cash flow are challenges to implementation in real life constitutional and political diversity. In fact, political corruption and one-party political system are interrelated phenomena, suggesting organically and complementary to each other. The real constitutional and political diversity and political pluralism are the only possible condition for the democratic development of the state, the rights and freedoms of man and citizen, translating ideas about the social state.
