Maryland's electoral maps show how proportional representation could solve the problem of gerrymandering

This week the US Supreme Court hears a case concerning the constitutionality of partisan gerrymandering in Maryland. Examining current, past, and alternative electoral maps, Alex Keena, Michael Latner, Anthony J. McGann, and Charles Anthony Smith find that by making districts more competitive, some redistricting plans can actually work against one party or the other. Only the introduction of proportional representation with multi-member districts, they argue, would mean a truly fair electoral system for Maryland.
