During the Belgian legislative elections on 13 october 1985, the Centre Liégeois d'Etudes de l'Opinion (CLEO), University of Liège, polled voters leaving the voting booths. The objective was to determine the characteristics of electors of the various parties according to the usual criteria of identification (sex, age, socio-economic status, education, religion, revenue, previous votes). The motives and wishes of the voters were also recorded (problems influencing the final vote decision, timing of the decision, attitude toward the incumbent government, type of coalition desired for the new government). The poll consisted of a representative sample of one thousand French speaking voters in the province of Liège. Most of the article presents the results obtained by cross-tabulating various identifying and motive variables with the political parties. In this way, we measure and demonstrate the relative importance of all the independent variables on the distribution of votes, except for sex which seems have little influence.
