Just in case anyone is thinking about statehood, I've decided I should make some hypothetical maps for Washington, D.C. and Puerto Rico. (Someday, in September, when we have data.)
NPR reports that the US Census Bureau might not release redistricting data until September 30, long after the usual dates in February through April, or the previous delayed estimate of July. BDistricting's fully automated approach should be just fine though. In a crunch we can rent a bunch of cloud servers and have good results for any state as little as a day after the data is available.
