I agree it’s not practical - but the retrocession of 1846 may have been unconstitutional, that’s worth looking into.
I graduated from high school in Alexandria. In Virginia, every student had to take the American Government course.
In that class we discussed the constitutionality of the separation. We agreed that it didn’t pass muster.
That area of Virginia is blue-correct? I want to be the one to tell them their vote doesn’t count anymore, would you? Call them racists while at it. The argument is power vs. slavery. They had both and it got us 700k dead.
