Thank you, king! No independent maps in Illinois until we have them nationwide.
At best Congress can mandate them for congressional districts, but not for state legislative districts. Since Pubs in their supermajority states say the same thing, your statement is equivalent of saying no independent maps for the state ever. The irony is that in states like IL an independent map is unlikely to affect the Dem control of the state, but would probably put a number of incumbents at risk in primaries or general elections with ungerrymandered districts.
Democrats have a bill and almost unanimous support for legislation mandating fair maps(there's an argument that under the 14th amendment congress does have the right to mandate them for state legislative districts or at least allow them to be challenged if they are gerrymandered in courts). Republicans can support it or propose their own standalone bill banning gerrymandering if they wanted.
