Keeping 5 regions in this one:
Look, I don't see why it would be a good idea to balance the regions in terms of population - for all we know, the current population imbalance is just a temporary problem, and soon the Midwest is going to be hugely overpopulated or something. I do agree that it should be addressed in terms of representation, which is why I introduced an amendment to reintroduce district seats to replace regional Senate seats, but population can move around. It's just... not, for some reason.
