In the Bethune-Hill racial gerrymandering case, special master Bernard Grofman has submitted possible remedial plans to the federal court in his report and addendum.

Unusually, he has given the court a variety of choices. In these choices, the affected area, in southeast Virginia, is divided into four regions. In each region, Professor Grofman has given the court several options. We give you a visualization of several of the plans here.

Today the Princeton Gerrymandering Project submitted an amicus brief evaluating the various plans. We find that the combination which does the most effective job of remediating the racial bias is also the plan that makes the most changes. We say as much in our amicus brief (see PDF).
