Sounds like Mr. B is throwing an idea we should think about. If there is enough public discussion, maybe an even better idea might come along. But to say that the current system is above reproach . . . . .
I have also provided a whacky idea called Tiered Democratic Governance. There are NO ZERO NIL NONE NOWAY political parties. I bet partisan writers from both sides would denigrate the TDG as an abhorrent idea from the other side.
