In this episode of Arcana, Gabrielle and Arianna examine Gerrymandering. What is Gerrymandering? How do we measure it and determine if it is a problem? This episode will examine the politics of gerrymandering with a discussion with Massachusetts Senator Jamie Eldridge, who is driving a bill in MA to create independent districting commissions. Then we will examine the science of gerrymandering by talking with Tufts University mathematics professor Moon Duchin. Prof. Duchin is leading efforts to examine the quantification of gerrymandering and to teach mathematicians and scientists to be expert witnesses and district map makers.
