Romania, like other countries in Eastern Europe, has gone from a totalitarian, communist, to a democratic political regime. This change in the political regime has also brought opportunities regarding the election of the president. After 1989 the presidential elections in Romania have had different orientations of the population regarding the political membership of the candidates. The study follows these mutations regarding the results of the presidential elections, in the two rounds, placing the political belonging of the candidates in the final round in the middle of general attention. The result highlights the relationship between those who have given a negative vote to a candidate, who has reached the final round, and those who gave a positive vote to the candidate they have simply chosen out due pure political beliefs. Within the 30 years since the change of the totalitarian political regime, the population of Romania has reached a major political change, oriented towards liberalism, in a very convincing percentage. These changes are based on a number of factors, which the study has analyzed on each geographic-historical province and, on each administrative unit, it has analyzed the componence of these provinces. The analysis has been made from the point of view of population structure by age group or socio-professional analysis, as well as from the level of education by historical provinces and therefore it explains the result obtained in the presidential elections.
