Abstract
This paper studies two-party electoral competition in a setting where no policy is unbeatable. It is shown that if parties take turns in choosing policy platforms and observe eachother's choices, for one party to change position so as to win is pointless since the other party never accepts an outcome where it is sure to loose. If there is any cost to changing platform, the prediction is that the game ends in the first period with the parties converging on whatever platform the incumbent chooses. If, however, there is a slight chance of a small mistake, the incumbent does best in choosing a local equilibrium platform. This suggests that local equilibrium policies can be the predicted outcome even if the voting process is not myopic in any way.
