costly and expensive gerrymandering state districts so politicians choose the voters will actually change very little

to end gerrymander .. it should be one person one vote.. and that would decide who wins. . not group up the votes into a area to water out one side or the other.

This is what happens when the President demands 5 new House seats from Texas.

You can't expect the other side to twiddle their thumb.

They need to all flip, "every"election
