Abstract
In the last few decades, the main changes in the electoral behaviour are the decline of the turnout and the development of volatile voting. Those two elements affect the political life of the countries because political parties have to adapt themselves to answer the expectations of the voters. The Institute for Democracy and Electoral Assistance made a survey to discover what factors influenced the turnout. According to Françoise Subileau, the decreasing turnout is due to 'the decline of ideologies, the disappearance of communism, and the loss of influence of the Catholic Church'. All of these elements led to a vagueness of electoral programs and to a confusion in the voters mind. The European Construction could also be a plausible explanation.
