Abstract

We analyze strategic voting under pure proportional rule and two candidates, embedding the basic spatial model into the Poisson framework of population uncertainty. We prove that the Nash equilibrium exists and is unique. We show that it is characterized by a cutpoint in the policy space that is always located between the mean of the two candidates’ positions and the median of the distribution of voters’ types. We also show that, as the expected number of voters goes to infinity, the equilibrium converges to that of the complete information case.
