This does not accomplish what PR accomplishes. In fact, it does the 
opposite -- over-represents the largest plurality at the expense of 
everybody else. How can you think otherwise?

 Can you prove that the ranking from a single-winner election is
proportional?

No. Nor did I say that it was. Notice that I didn't call it PR or
Proportional Representation. When I said Whatever can be accomplished by
PR can be accomplished by an at-large single-winner election, I was
comparing the suggested multi-winner use of a single-winner method to
PR--speaking of it as something _other than_ PR. That shouldn't be taken as
saying that it is PR.

Yes, it wasn't the best choice of wording. No, it didn't imply that
multi-winner use of a single-winner method is PR. I spoke of it as something
other than PR.

All I meant was that a single winner method, used as I described, can elect
a national Congress, at large, without districts.

Of course. You're talking about PR. I wasn't talking about PR. I was talking
about the use of a single-winner method, without the goal of
proportionality.

I have nothing against PR--except that I don't like the idea of unpopular
parties being seated in Congress :-)  But PR would be fine anyway. It works
fine in Europe. There would be nothing wrong with borrowing from Europe. As
I said before, if there were a referendum tomorrow about whether to adopt
European or Australian PR, I'd vote Yes on it without hesitation.

One advantage of party list PR is that it allows the use of the most
proportional PR formula: Sainte-Lague.

Sainte-Lague isn't the only PR formula that is unbiased with respect to
party-size, but it's the only unbiased formula that doesn't share the
avoidable errors of STV and Largest Remainder.

 Also, I like emphasis on party platforms instead of personalities and
hairdo, etc.

But I recognize that many would like to vote for individuals, even in a PR
election. Of course that can be done in open list systems, such as those in
Belgium, Luxembourg and Switzerland. The best of both worlds: Optimal
proportionality and opportunity to support individual candidates. I'd
thought that Finland had open list, but Juho says that they don't.

Forget those. The familiar already-used methods are fine. The last thing
you'd want to do would be to invent and propose something entirely new. If
all you want is PR, then stick with existing familiar PR systems.

But I'll say again that, for the U.S., PR would be a whole entirely new and
different system, a new concept of government. Forget it. A better
single-winner method is nothing more than a better way of doing what we
already do. And Approval is nothing other than Plurality with its ridiculous
forced-falsification rule repealed. Ask for less change. Get something.

And no, I don't recommend including at-large Congressional elections as part
of an Approval proposal :-)

I propose nothing other than replacing Plurality with Approval. No other
change in the electoral system.

Further refinements and enhancements could be proposed later.

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.

 3. But districting needn't have a gerrymandering problem, even if

 assumption?

 Draw the district lines by some simple rule that doesn't leave any
 human discretion or choice. It would be completely automated, but it
 would be so simple that it would be very easy for anyone to check.

 For example: You could divide the country (or state) into N1
 latitudinal bands such that each has the same population/average
 longitudinal width.  Then divide each latitudinal band into
 longitudinal sections, in such a way as to give each section the
 same population, and so that there are the right number of such
 sections overall.

 But of course you wouldn't have to use latitude and longitude if you
 don't want to. On a map, on any projection, that you choose, use a
 rectangular grid of lines, drawn similarly to the way described
 above. If you use a gnomonic projection, then all of your district
 lines will be straight lines on the Earth (great circles). If you
 use a cylindrical projection, then it will be as described in the
 previous paragraph. But it could be any projection you like. I'd
 suggest that gnomonic and cylindrical (using parallels and meridians
 as described in the previous paragraph) would be the main two
 choices. Districts divided by parallels and meridians, or by
 straight lines (great circles).

 The point is that it could be done by a simple rule that would have
 no human input, no human choice. What if it divides a county or a
 city? So what? No problem. The rule could be that houses would be
 all counted on whichever side of a line most of the house's area
 lies.

 It could be automated of course, but the result could easily be
 checked by anyone.

 To change the subject a little, I'd like to bring up another
 geographical government suggestion, while I'm at it: Partition.

 It doesn't make any sense for people to have to live under a
 government that they don't like, with people whom they don't agree
 with or don't like. So why not just divide the country up into
 separate countries, according to what kind of government people
 like? It's ridiculous to make everyone share the same county, when
 they want different kinds of country.

 It would be like a PR election, except that it would be for square
 miles instead of for seats.

 Though, like districting, the partitioning of the country could be
 (1) by an automatic rule, with those same rectangles (I like that),
 or (2) it could also be done by national negotiation in a PR
 negotiating body, or maybe by a proxy DD negotiation.

 I like the quick simplicity of (1). But (2) could _maybe_ be done in

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
