Abstract
Classical power analysis does not involve preferences of players (parties). Classical power indices are constructed under assumption of equal probability of occurrence for each coalition. The paper contains a proposition of relaxation of this assumption, based on extended Shapley–Shubik power index approach.

Keywords: power index, ideological preferences, ideological distance
