Well, there is merit to the gerrymandering decision today. It makes sense that is not a good thing for America, but there is no legal nor constitutional ground to disallow it, as I understood it.
The Congress must make it so it can’t be done, and we’re back to square one, because they won’t do it.
Don’t expect the Constitution to solve every issue. It is an imperfect document as I have been finding out time and again as it is now being tested hard.
