i thought of an idea where the doj draws "interstate districts"

[Bleeding heart conservative, HTMLdon]

in legislative reapportionment, the counties aren't given those rights. Why the f--- should the states? You don't have the county board of supervisors redraw legislative districts within their county do you?

The county is an administrative jurisdiction created by the state.  The federal government is a compact between states that is created by the states.  In a Constitutional sense, the state government is the most powerful entity.
