Query: Measuring Political Gerrymandering   In 2016, a Wisconsin court struck down the state assembly map due to
unconstitutional gerrymandering. If this ruling is upheld by the Supreme
Court's pending 2018 decision, it will be the fist successful political
gerrymandering case in the history of the United States. The efficiency gap
formula made headlines for the key role it played in this case. Meanwhile, the
mathematics is moving forward more quickly than the courts. Even while the
country awaits the Supreme Court decision, improved versions of the efficiency
gap formula have been proposed, analyzed and compared. Since much of the
relevant literature appears (or will appear) in law journals, we believe that
the general math audience might find benefit in a concise self-contained
overview of this application of mathematics that could have profound
consequences for our democracy.
