Sociophysics, Renormalization group, Hierarchical voting
We review a model of sociophysics which deals with democratic voting in bottom up hierarchical systems. The connexion to the original physical model and technics are outlined underlining both the similarities and the differences. Emphasis is put on the numerous novel and counterintuitive results obtained with respect to the associated social and political frame- work. Using this model a real political event was successfully predicted with the victory of the French extreme right party in the 2000 first round of French presidential elections. The perspectives and the challenges to make sociophysics a predictive solid field of science are discussed.
