Abstract: Representing voting rules in the unit simplex by considering only the distribution of voter preferences is a classical approach to voting theory, for example in the books of Donald Saari. However, it has not yet been applied to the distance-rationalization framework. We aim to analyse general properties of distance-rationalizable voting rules by looking at the geometry of their consensus and metric under this representation. This leads to interesting geometric questions involving metric spaces.
