If people try and force the regions out at least leave the region boundaries the same for election purposes, that keeps it kinda the same.
I would agree. If the regions were abolished, along with governors etc, then it would be fair to create at least 2-4 new seats on the national legislature to compensate, perhaps allowing existing governors to serve out their term, but as members of the Senate.
As for a two house system, it could
work, but it could also overcomplicate the legislative process. The regions have alot of life in them yet, and I thoroughly enjoyed serving mine, but if things don't pick up them may have to be sacrificed. Another option could see the regions reduced, to perhaps 3 but all of these are radical possibilities.
I think those of us, myself included, who pushed for and participated in the Constitutional Convention were perhaps too focused on the wrong issues and were ignorning the 'elephant in the room'
