Yes, it would seem as though DC could raise their own funds to supervise it themselves. I hope that they can.
Nonetheless, this is a Nanny State attempt to stop DC from following the will of its own people. Such shenanigans are why I believe DC, Puerto Rico/Virgin Islands and Guam/Pacific territories should have actual voting representation in the House — not the Senate, though, since they aren’t states - since their people have to live under Congress’s stupidity, too.
If they are not states they should not get actual members in Congress.
My grocery store sells green beans.
There has been no funding that I know of to enable this green bean initiative.
