That's right. The Iron Law of Oligarchy. Nice Wikipedia article on
it, last time I looked. Oligarchy is inevitable and necessary, but
the trick is to contain it and keep it responsible, to members who
have means to be informed, information that is generally trustworthy,
and who retain as much individual power as possible.

The original goal still exists for FairVote, but has largely been
eaten by the IRV monster. That the preceding organizations to
FairVote co-opted the PR movement was noticed early on, by the
original PR proponents. If Richie realizes the problems, he doesn't
let on. He's a dedicated, bulldog political activist, and, in
general, I consider his "office" to be part of the problem. It's
necessary in an adversarial system, far less so in systems that
attempt to find social consensus.

Yes. The same is true, by the way, with Bucklin. It worked; when it
"failed' it had simply reverted closer to Plurality due to bullet voting.

FairVote has sold IRV most successfully in jurisdictions that were
using top-two runoff with nonpartisan elections, and in that
environment, it's clear that dropping TTR for IRV is quite
equivalent, in practice, to simply running Plurality, which is a lot
cheaper. I have seen one fairly clear exception, the Ed Jew District
4 Supervisor race in San Francisco in 2006, and in that race, we had
visible markers (the names of the candidates) that identified ethnic
affiliation, apparently quite similar to partisan affiliations in
partisan elections. It stands out like a sore thumb in the vote
transfers, and apparently Jew actually only campaigned to Asians and
advised them to rank all the Asian candidates. Since the district has
a high Asian population.... So this "exception" actually proves the
rule. Nominally non-partisan, but, in fact, highly partisan.
Top Two Runoff is an improvement over Plurality, and is the
most-established election reform in the U.S. And FairVote has been
shooting it down with its efforts. It's tragic, in fact.
In the long run, though, it will probably prove to have been
suicidal, as results from all these trials accumulate and are
analyzed by people who aren't nailed to the FairVote agenda.

That problem is fundamental to representative democracy, though. Some
kind of representative democracy is necessary in order to handle
scale, but two approaches ameliorate the problem. First of all, make
sure that the choices of people for representatives are respected and
implemented as accurately as possible, so that, as far as possible,
representatives are chosen instead of being elected, so that the
original voters are truly represented, accurately, and not through
major compromise.
In the end, some kinds of compromise may be necessary, but it turns
out that the impact of compromise can be so minimized that it becomes
of far less importance.

However, this, then, confines voters to representation by political
parties, essentially. It leaves independent voters more or less out
in the cold.

Voting for inheritance orders prevents the negotiation of shared
representation. The beauty of Asset is that it allows intelligent
negotiation, with minimum constraint. And when Asset is used in a
hybrid system, not merely as an election method, *representation in
decisions of an Assembly is absolute,* the only compromise that has
been made is in *deliberation,* i.e., it is the minimum compromise.
Just because you voted for yourself in an Asset election does not
mean that you can stand up in the Assembly and take up everyone's
time with a speech, or that you can introduce a motion. You will have
to find someone with a seat to do these things, or at least to ask
the Assembly for permission for you to do it (i.e., the speech).
The separation of deliberative rights from voting rights that I
propose is not entirely new, it exists when an Assembly submits a
question to the voters, but in a general election, guaranteed, there
will be lots of voters who don't understand the issues and are just
reacting to appearances, or to media impressions that can be created
by skilled marketers.
The real election in Asset is immediate: electors are chosen with
certain powers that are unconditional.
(If there are security concerns, it's possible to require that
electors receive some minimum vote count, which would be large enough
to allay the concerns. Under truly difficult conditions, this would
be the minimum number that allows the State to provide some level of
security for electors who are publicly announced. In this case,
electors would submit a sealed ballot before the public election,
with a list of alternates to serve if they cannot serve for some
reason. But under more settled conditions, the number could be one
vote. If there are concerns about vote coercion, it could be three.
As to vote buying, in systems that are thoroughly representative,
vote buying, to be effective, would have to be so widespread that,
especially if it's illegal, it would be more cost effective to simply
make an offer to the State of compensation for whatever you want to
do. Legal, too. Buying votes in an Asset election strikes me as quite
a waste of money, because to exercise much power that way, you'd have
to buy a lot of votes!)
"Absentee voting" on actual questions before an Assembly, i.e., where
an elector submits a vote on a question without at least being
exposed to the debate results, I would not allow. Rather, an elector
would either have to be present at the Assembly to vote, or could
vote on-line through a web site which contains the record of debate,
committee reports, etc. If the elector votes, it then weakens the
vote of any seat that has been chosen to represent the elector. I
would not allow proxy voting by seats, unless through an entirely
separate system. I.e., the seat would always vote (or abstain)
personally and would not separately cast votes for different factions
of electors. But a system might exist where an elector may designate
a revocable proxy to vote in the elector's place. But I've mostly
been assuming that an elector either allows the seat to vote and
leaves it at that or votes directly.
I'm also *not* assuming delegable proxy as a legal system, at least
initially, where transfers are binding and not revocable. When an
elector votes in the seat election, the elector registers the vote.
It's public. The elector may assign any number of votes, including
fractions of a vote. A "contract" of transfer may exist, providing,
for example, that votes are returned proportionally, if excess (if
the receiving candidate has more than the quota), or, alternatively,
that the seat may transfer excess votes personally.
I'd probably allow a seat I vote for to transfer. The reason? The
candidate I transfer to is probably in a better position to know the
other candidates than I am.
But I also assume that procedures will exist for revoking transfers
even after the Assembly is seated. And this leads to consideration of
the use of Asset to handle recall. But, remember, I'm proposing Hare
quota, which will often leave the assembly a seat short, or even a
few seats short, depends. If a few votes of a quota are rescinded,
I'd argue, the seat could continue to serve, with reduced voting
power, until and unless those votes were replaced, and voting power
would have to fall below some threshold to actually result in loss of
deliberative privileges. If, then, a few extra seats are elected,
there is no harm. The electorate is still represented, and gaining
extra seats with reduced voting power for each -- i.e., the same net
voting power, simply decreases the efficiency of a faction. Seats are
merely filters, preventing overwhelming deliberation with noise.
(And the Assembly can censure and sanction members who are
disruptive, it is a traditional right of deliberative assemblies,
necessary for them to be able to protect themselves.)

First of all, I'm not recommending delegable proxy (liquid democracy
is an early name) for anything but voluntary organizations. Asset
Voting, though, is close enough. When systems are as open as DP or
Asset, "vote-buying" takes on different significance. I don't want a
garbage dump in my neighborhood, I'd oppose it. But what if the
proposed dump operator offers me $10,000 to withdraw my opposition?
What I think about this is that it is only offensive if secret. Why
shouldn't my neighbor get the same? Or at least the opportunity!
I've elsewhere detailed how an attempt to corrupt a proxy in a DP
system could easily lead to a mouthful of hair for the would-be
corrupter. They pay the money, they get the open support of the
proxy, the proxy ends up looking very good to the constituents, who,
on this issue, vote directly, bypassing the proxy's vote. I've
recommended in DP systems that proxies *not accept* votes from large
numbers of constituents, or, at least, that they understand the
problems created if they do. If I got large numbers of requests to
serve, I would instead recommend that they choose someone who has
chosen me. And then I can communicate with all of them through direct
(and private) communication with a handful of individuals. So I've
been offered some huge sum to exercise my influence. Publicly, I
promote the idea, using the best arguments provided to me, and
perhaps I shut up about the reasons why it's a Bad Idea. But I'm in
direct communication with my set of direct clients, and we discuss
everything, routinely. And it would be very easy to make sure that
they are aware of the counterarguments and that I'm voting as I vote
because of, shall we say, special considerations. So I vote and argue
as I'm paid to do, and my clients decide that they just don't like my
opinion on this particular issue, so they vote directly.
Very expensive to corrupt a DP system. The corruption we are
accustomed to is made possibly by narrow nodes of voting power, such
as an elected representative, where one person being corrupted can
shift a result, where it takes only a few to produce, say, a desired
committee report. In addition, the requirements of electoral
democracy, with contested elections, are such that candidates
constantly need money for campaigning, so it's a perfect setup for
corruption, and much of it is even legal.

I don't think that the power of direct representation has been
realized. In an Asset system, every voter could look at the vote
transfers and see exactly where their vote went, and how it was
exercised on any question. There is individual responsibility and
accountability. What I expect is that the Assembly would become "our"
assembly, and any frustration left would be natural. I.e., if your
position is in the minority, and you can't, even with reasonable
representation, shift the opinion of the majority, well, you might be
frustrated. But you'd have had ample opportunity to be heard, and
many ways to get your message to the Assembly if the arguments are cogent.

Of course. STV is pretty good for PR, used properly. But Asset knocks
the ball into a whole new park.
