Discussion of the relationship between parties and the electorate is often based on the notion of partisan constituencies, that parties adopt policy positions that correspond to the average position of the party supporters. In contrast, the Downsian “spatial model” assumes that parties are purely opportunistic and maneuver to gain as many votes as possible. A third, more empirical model, based on the early work of Stokes, assumes that voter choice is based on the evaluation of each of the party leader’s competence or ability to deliver policy success. Such an evaluation can be provided by individual voter overall assessment in terms of the leaders’ character traits.
This paper attempts to relate these three classes of models by examining the elections in Great Britain in 2005 and 2010. Using the British Election Study, we construct spatial models of these elections in Great Britain as well as in the three regions of England, Scotland and Wales. The models incorporate the electoral perceptions of character traits. We compare the equilibrium vote maximizing positions with the partisan positions, estimated by taking the mean of each of the parties voters’ preferred positions. We define an equilibrium to be a stable attractor if the vote share at the equilibrium exceeds the share at the partisan position by a significant proportion (determined by the implicit error of the stochastic model). We infer that none of the equilibria are stable attractors, and suggest that the partisan positions are also preferred by the party activists, the key supporters of each party.
