*Consider a two-dimensional case. Any policy <math>z_{i}<math> is characterized by coordinates (x_i, y_i)

*In first stage we vote on <math>x_{i}<math> . and obtain policy equal to median voters bliss point x_m. In second stage we vote on y_i and obtain policy equal to median voters bliss point y_m, so we obtain unique outcome z=(x_m, y_m)T is always distributed equally among n districts so <math>t_{i}=T/n</math>.
