National: Can an election district have too many minority voters in it? | Constitution Daily
Under the Constitution, government officials are not supposed to sort people by race, for any public benefit. If they do, they have to come up with the strongest policy reasons, and even those will be severely tested in court. The really hard part comes when race is taken into account as an attempt to remedy past racial discrimination. When does that become a new form of discrimination? Courts have long struggled with that remedy issue, and in no field of law has that effort been more difficult than in drawing new election districts, as almost always has to be done after each new federal Census. Populations do shift over 10-year spans, and districting maps thus may get out of date. Racial calculations do enter into the map-drawing process, for the simple reason that federal voting rights law requires it.
