Well, in theory, DC has the whole congress that is supposed to look out for it, so the have 'every' representative of congress...(Back to part of my post...)
Off the top, looks the easiest way to fix it may be to allow the voters to vote as voters of Maryland.....Sounds sensible,,,,,

Then hey, California or Texas could stand very well as a country in their own right...
And what about the US flag!....Lol
