Performance or representation? The determinants of voting in complex political contexts

Abstract

This paper analyses the way in which voting decision combines factors regarding government performance and the representative nature of the rulers. We have selected four Spanish regions with different degrees of nationalism and different parties at autonomous regional and central government levels. Voters make decisions in a two-dimensional space (ideology and nationalism). We calculate the relative importance of each dimension and show that ideology affects all voters equally, whereas the nationalist dimension only affects nationalists. Using conditional logit estimation techniques, we analyse a 1992 survey of carried out by the Centro de Investigaciones Sociológicas, which shows us that (i) there is a coat-tail voting effect, so that the party in power is rewarded or punished at autonomous regional level, (ii) nationalist voters are more indulgent than non nationalist voters when they have a negative opinion of the regional government performance, and (iii) the more exclusionist the nationalism, the stronger this effect will be. We consider that these effects are due to the fact that nationalists vote on the basis of representation rather than government performance.
