The way to cause the other party to support a national shift is by first shifting the battleground states that we control.
Think asymmetric.
Then, the other side will see that they can reduce their disadvantage by shifting all the states.
In the long run, I’m not sure this favors one party over the other. It favors the party that controls the majority of state governments (which, right now, is us), since the states control re-districting.
And I think that’s a good thing.
Let’s do something restore the balance between our state governments and our national government.
since the states control re-districting.
**************
True to a degree but don’t forget that the VRA put nine states under the feds for approval in redistricting and it has expanded to include some counties/locales in other states.
That said even under VRA approval those states have been able to elect Republican delegations.
