I don't think that matters though. I'm more concerned about the broader metropolitan area where all the people with all those powers and all the people who are on their coattails reside. Which is currently Virginia and Maryland. Shrinking DC proper is basically a no-op on that front. If anything were to happen it should probably be the creation of a "middle" Virginia on some sort of Northeast southwest line so that the metropolitan area is split among three states to dilute it. Failing that just split it among VA/MD, that'd basically leave the status quo unchanged with regard to interests and power but at least make less people's lives subject to political football.
