Longtime stability of the voting behavior is a phenomenon often observed and its importance is appreciated by researchers. Election results show that since 1989 Poland has been divided by cultural and civilization gap: the north-western part expresses its commitment to the liberal and left values, while the south-eastern part remains strongly traditional and Catholic. The direct background of the nowadays voting divisions goes back to the period of 1940–1947 characterized by dramatic events of war and the considerable change of borders. Signifi cantly, in the beginning of XXI century voters living in the great towns changed their voting behavior and instead of supporting the political camp being still very popular in the anticommunist south-east, began to prefer the moderate political parties that also use to dominate in the north-west Poland.
