This data contains NAD83 (HARN) EPSG codes for every U.S. state.
Since redist uses projected geometries, it is often a good idea to use
projections tailored to a particular state, rather than, for example, a
Mercator projection. Use these codes along with sf::st_transform() to
project your shapefiles nicely.
