Put DC residential areas back into Maryland.
Maryland and especially Baltimore don’t want DC, and DC does not want Virginia. Are you aware that DC was once a square, but the part in Virginia was returned because they were upset when DC was going to abolish slave markets in ALL DC (bad for diplomacy). So the supporters of the slave market in what was formerly Virginia raised holly heck and got their chunk across the Potomac back. DC has too many blacks not to be upset about being part of that, and there are those in Virginia who really don’t want more blacks. So DC continues to prefer statehood, especially when they consider those 3 small states are represented and DC is not and has never been.
