Re: [EM] Gerrymandering solutions.
As far as the US goes, the Supreme Court (law of the land) has officially declared that gerrymandering is just fine. The only solution to gerrymandering is for voters to elect representatives who won't draw the districts to benefit themselves. Aint happening in Texas or anyplace else it matters. We all know there are good and fair ways to draw districts, but the US Supreme Court has said those are not criteria they care about. -Original Message- From: election-methods-boun...@lists.electorama.com [mailto:election-methods-boun...@lists.electorama.com] On Behalf Of Michael Ossipoff Sent: Wednesday, June 06, 2012 8:22 PM To: 'Ted Stern'; election-methods@lists.electorama.com Subject: Re: [EM] Gerrymandering solutions.

But (2) could _maybe_ be done in such a way as to ensure that each new partition-country has, to the best extent possible by negotiation, equally good land, by whatever standards its people want to bargain for. Of course an overall census could be taken periodically, and the process repeated, to take into account people who have voted with their feet. But those adjustments wouldn't be necessary, because the initial partition would let everyone live in the govt they like best. But, though I don't watch tv, I used to watch it along with the family I was part of, so what about a family like the one in All in the Family? Should Archie Bunker's daughter have to remain in his country? Likewise the family in A family Affair (if I've got the show-name right). It is not your fault what country you're born in. So there would be a strong case for letting people continue to choose what country they want to live in, even after partition. Of course then it would be necessary to repeat the initial partition process to adjust the national borders to the new populations. Maybe migration should only affect borders when it's by people who were born in the country that they're in, as opposed to people who chose that country at partition time. But migration must be distinguished from fecundity, for this purpose. A country shouldn't be able to
