The American winner-take-all district system introduces a significant opportunity for manipulation by district drawers and enables large discrepancies between the popular vote and political representation. In this paper, we present a novel column generation heuristic to minimize the expected difference between the seat share and vote share for district based elections. Our approach relies on random tree partitions to generate a set of compatible districts that admit an exponential number of distinct district plans.
