La influencia del conocimiento político en las decisiones de voto.

This paper discusses and compares two kinds of logic that explain electoral behaviour: the performance vote and the ideological vote. To be exact, this paper puts one of the main hypotheses of both theories to the test: that the rules guiding citizens' voting decisions are the same, regardless of their level of interest, knowledge and information about political matters. In order to do this, empirical material taken from post-electoral surveys in four democracies —Spain, Portugal, Hungary and Poland— is analysed. The data belongs to the second module of the Comparative Study of Electoral Systems (CSES 2005) programme which contains information on citizens' electoral conduct and knowledge of politics. The results indicate that while the influence of political knowledge on the logic of the performance vote is clear and conclusive, it is much less conclusive in the case of the ideological vote. All this suggests that democratic control of governments through sanctioning their performance requires citizens to have minimum levels of knowledge and information about politics.
