In preparation for the Supreme Court’s hearing of Gill v. Whitford, a group of 15 historians, including 11 AHA members, filed a brief of amici curiae that laid out the history of equal representation in early American voting systems and why the Court should strike down Wisconsin’s district maps. The historians are joined by numerous other organizations, many of whom agree that Wisconsin’s 2010 redistricting plan contains a statistically significant bias towards the party that drew it. A decision on the case is expected by June 2018.
