Hopefully, there'll be some light and not too much heat, although we tend
to purport that so much is at stake that the latter is inevitable... I
really do appreciate the hard work you put into your reply to me.

dlw: In politics, all campaign promises are not hard and fast, but
statements of value and any push for any election reform is a political
election.  They must simplify the message to get it across to voters.

That's because ranking umpteen candidates is another bowl full of cherries.
 Once again, in a world where relatively few voters want to rank even 3
candidates, it doesn't really matter.  The diffs in the Xs are not serious,
all things considered.

At the end of the day, it's an empirical question how serious the
simplifications are.  I've no doubt that the opponents of electoral reform
will have a strong incentive to make the most of any conceivable perceived
flaw in any proposed electoral reform.

dlw: The line of causality is not complete... The transitional case where
there are not two major parties centered around the de facto center
presented an opportunity for the opponents of IRV to wage a strong campaign
against IRV.  This succeeded in repealing IRV by a small margin.  If more
well meaning electoral analytically informed people had stood up for IRV3,
it would have dispelled the misinformation campaign.  For IRV>> (2 rounds
if nobody gets at least 40%) and those were the only two options on the
ballot.  So if people who preferred alternatives to IRV like yourself but
are smart enough to read the writing on the wall about what's going on had
soft-pedaled your criticisms of it then IRV3 would have remained and you
couldn't point to Burlington as "the" proof that it's god-awful.

dlw: Well, it'd still beat a monarchy...  Believe it or not, an angel does
not lose their wings everytime somebody votes strategically...  The only
strategic voters with IRV would be supporters of a "major" party that has
not positioned itself around the true political center.  This is not the
case with FPTP.

dlw: You're getting too theoretical.  In real life, there are economies of
scale and scope that hinder the ability of new parties to squeeze major
parties centered around the true center.  Third parties can only gain
ground if the center moves and the major parties out of inertia fail to
move with it.  As such, the possibility a VT Progressive party can win even
if it's not the CW when the two major parties fail to adapt to the moving
center will force the two major parties to adapt more often.

dlw: You don't work in advertising/marketing do you?  If people vote
honestly then the predicted outcome is that a repositioning of the parties
ends the perceived problem.  So FairVote is right that their system will
work if people vote honestly.  Unfortunately, most rational choice models
used do not take into account the long-run endogeneity of
party-positioning.  It all serves to reduce | Xirv -Xoth|.

And besides, it is the simplification of the message by FairVote that Pirv
is >> Poth..., don't kill the paradigm-shifter, there'll be plenty of time
for further experimentation later on..

dlw: When you and anyone else start having the real world successes in
marketing electoral reform to the voters of the US, I will give you the
same treatment as FairVote.  But as of right now, they deserve it.

dlw:  When an election rule gives strong incentives for the two biggest
parties in an area to follow the center then it is safe to vote however you
want.

dlw: "later" may be a long time... You're discussions over the various
election rules are not easy for most people to follow and it won't be hard
for the opponents of election reform to spin the matter and otherwise keep
the P_oth s down by playing the factions off of each other.  Plus, I think
there are utilitarian reasons IRV3 was the best election rule to start
with(which also are not the right sort of reasons to use when marketing
IRV), which will also P_oth down, so long as our current system remains in
place.

dlw: I believe I meant p(not(Xoth >> Xirv) | (electoral realism)) >>0.  My
complex ecology is based on what I believe to be true for voters and the
USA.
IOW,  |Xirv-Xoth| <<Pirv-Poth in the short-run based on my complex ecology,
which includes the presumption that in at least the short-run there will
continue to be a strong tendency to two-party domination in the USA.  I
also argue that a two-party dominated system could end up being not so bad.
 The rhetorical thrust of this "complex ecology" or political vision is to
parry what I perceive as a counter-productive perfectionism among many
well-meaning folks who insist we need to do whatever it takes to end our
two-party dominated system.  I think such is less likely and harder to get
support from many US_Americans who are accustomed to a two-party dominated
system.

IOW, I want change so badly, I'm willing to take the path of less
resistance and trust that extra-political cultural changes will enable the
crucial sorts of changes needed.

dlw: Yes, a key point for me is that the tendency for there to be two major
parties strongly reduces the differences in values across single-winner
election rules, though that's not the only reason the compression of diffs.
 It is also true that the replacement of FPTP with IRV will not end this
tendency, which is one of the reasons Pirv>>Poth.  So my arg is buttressed
by how the USA tends to be dominated by two parties. To avoid circularity,
I simply need to give a compelling reason for why this fact is unlikely to
change in the short run.   I think one of the most robust reasons for this
tendency are the relative strength of our president and her/his nationwide
election.  It's quite costly to run a serious presidential election,
regardless of the election rule used, which creates economies of scale that
makes our system favor bigger parties.

As such, there's not evidence that if we only pushed some other better
election rule than IRV that we'd have a multi-party system instead of a
two-party dominated system.  We're not near the tipping point or the burden
of proof is on you to argue such.  But this does confirm my conditioning of
the relative valuing of various election rules on the continuation of
two-party domination in the US, which in turn buttresses my contention that
we focus on the Ps, not the Xs, in our electoral reform activism.

dlw: In a system that primarily uses first-past-the-post election rules,
smaller third parties that specialize in "more local" elections are more
fit than minor parties that try to rival the major parties.  They are more
fit because there are diseconomies of scale in forming "community" that
produces volunteer resources that can take the place of the $peech that
reinforces intra-party discipline in major (and larger minor) parties.
 Likewise, if those in power are almost all from two major parties then it
makes sense that in the short run any election reforms adopted will not
strongly challenge this tendency.

The fact that some US people want an end to 2 party rule does not matter
wrt the real-politiks of strategizing electoral reform in the US.  Those
who really want an EU multi-party system are a minority in the US.  They
are not the ones who are apt to prevail in a FPTP dominant political
system.  My point is that we can find in US history evidence that we don't
need to become a lot more like Norway to make our system work considerably
better than it has in recent history.

dlw: At issue is more so how much Xoth > Xirv.   I think center squeeze
doesn't matter so much when the center is a moving target.  As for the
embarrassing outcomes of IRV, I think if more of us do-gooders stood up for
it(preferably in hybridized form), it'd have fewer reversals.  For with
IRV, the strategic voters won't be the dispossessed minority dissenters
from the status quo but rather the stalwarts of the major party that
refuses to adapt to reposition itself around the true center.

Yee models take the position of the parties as given, I'm saying it's an
important endogenous variable in real life.

"you think the de facto center is somehow within IRV's safe area but not
Plurality's safe area."  I don't recall this arg, most of your criticisms
of IRV are even stronger against FPTP, which suggests the value of
strategically supporting IRV against FPTP or something close to FPTP.

 dlw: I don't understand what is PR enough or "IRV won't pull too much".
 My system is meant to prevent any party from dominating, increase the
number of competitive elections and make the two dominant parties have to
adapt to the moving center, hopefully shifted by groups like #OWS.
  I don't expect any of us are going to get to fine-tune...  It's going to
be political jujitsu, "less is more" for quite a while by virtue of the
reality of how difficult it is to make electoral reforms in a two-party
dominated system that tilts too easily to effective single-party domination
at the state and national levels.

I don't support IRV alone.  FairVote is going to be pushing for American
forms of PR, which pragmatically will be like I have argued.
My arg is that since |Xirv-Xoth|<Pirv-Poth, at least in the short-run, and
PR is also going to be on the agenda then it's important for us to set
aside our dickering over X and support FairVote(and IRV) in the coming
year.  Let's bolster the short run level of Pirv, trusting that Poth's
chances will be higher once IRV has replaced FPTP as the primary
single-winner election rule.

 dlw:It didn't get the CW. But it would have moved the center and then
gotten the CW if it had been continued, hence Xirv is not << Xoth.  It
"fails" to maintain a stable 3-party equilibrium around the center.  This
is part of why it tends to continue effective two-party rule, but that does
not imply Xirv<<Xoth as well.

I didn't appeal to EU, I appealed to US history.  We had a contested
two-party rule in the past in the US with FPTP.  All it took was the use of
a quasi-proportional state legislative election and the ability of third
parties to gain ground in state politics, like with the VT Progressive
party or the NY's Working Families Party.  At issue is why it became
"not-so-contested".  The use of FPTP helped, so did the cold war red scare.
 The ending of 3-seat state reps elections in IL also probably played a
part... but the most important point for me is that US politics worked a
lot better prior to the past 40+ years, while there was a two-party
dominated system.  As such, that must not be what is so bad.  Your arg goes
against the felt experiences and national pride of US_Americans and is
thereby unlikely to help change things here.

dlw: You are right that it regards perception.  I believe IRV is defensible
as a complement to American forms of PR.  It'll take us forward.  We just
have to defend it better the next time it's attacked/slandered by cases
like Burlington.  It didn't fail, because success is not always getting the
CW winner.  It made our system gravitate towards the moving center, thus
|Xirv-Xoth| remains smallish.  What happened was IRV had an outcome that
made its continued use vulnerable and those of us who want change got
divided and conquered by those who oppose change.

And wtf, Yes the burden of proof is on your side.  You're not a leader of
electoral reform, you're arguing for alternatives that could sidetrack us
from moving forward.  And the sad fact of the matter is that electoral
analytical args have not settled the question of what is the best electoral
alternative to FPTP and are not compelling in real life and there's a
paucity of empirical evidence about the use of Condorcet etc. in real life
political elections.  That's what really is the case.  Get out of the
cloud, either you attack the value of Pirv in the short-run or you bolster
it for the short run.  That is the choice you face.  Right now, it's too
soon to let a thousand flowers bloom on electoral reform movements in the
US.

dlw: I argue from expediency.   The flaws of a system that only uses
single-winner elections are so strong in the US that what some might term
as quasi-PR might be justified simply because of the need.
That's why I'm going to support whatever FairVote and other electoral
reform orgs decide to push for at state levels, because it's not worth it
to sock it out over getting it perfect...

dlw: I said 3-seat LR Hare.  It's just like FPTP, but the top 3 candidates
get elected, unless the top candidate beats the 3rd place candidate by more
than 1/3rd of the total vote.  This enables a 3rd party candidate to get
elected with as little as 10% of the vote if the top candidate gets less
than 43.3% of the vote.  It's even better than Ordinary 5-seat PR, and it'd
have more competitive elections...   It's the only party-list form of PR
that doesn't have party lists(there's tacitly a list of 2 or 3, since the
candidate could announce their vice-candidate(s) beforehand or select them
after they've won multiple seats).  It also doesn't ask voters to rank
candidates, which is probably better in a "More local" election that's
likely to get less of their attention.

I think the morale of the story is the need to find a middle-way between
our ideals and the existing power-structure.  This is why I support a
2-party dominated system that is contested and can't tilt to effective
single-party rule.  What you said about 3rd parties gaining ground with PR
used, can also be said for a handicapping of the rivalry between the two
major parties when 3-5 seat PR(or quasi-PR) elections are used.  US history
suggests from IL that the use of such in state reps elections would be
enough to prevent any party from dominating a state's politics.

>
> KM: In another post, you claimed RBJ was "defeatist".


dlw: The context was to say that the defeat of IRV in Burlington had

time...

dlw: No, because they won't be happy about the use of quasi-PR in "More
local" elections.  If they had been happy with such then they wouldn't have
gone to such lengths to remove it from use in IL in 1980.  They like having
a state's politics tilt to single(their)party rule and want the same for US
nat'l politics.

If Am forms of PR is introduced then it'll help IRV/single-winner reforms.
 This has been the desire from the get-go, as far as I can tell.
 FairVote's past advocacy of IRV alone has been out of expediency so they
could maintain their org ready in preparation for a year like this one when
anti-duopoly/incumbent sentiment is strong.
The only fine-tuning needed of 3-5 seat PR in super-districts would be to
give the leadership of the party-in-power enough controls so they can get
things done, in spite of the existence of a divided gov't.

dlw: And my point is that we need to rally together to do the same thing
and that includes burying the hatchet over IRV as the de facto
single-winner alternative to FPTP.  This can be coupled with prioritizing
PR over the use of IRV, which I think is going to happen in the US.

dlw: Because the de facto political center is quite different across
states.  This is why there's a VT Prog  party.  I reckon that there'll
emerge versions of Christian Democratic parties in the south in the near
future, inasmuch as I don't think the GOP religious right activist base are
going to be happy with how they've been strong-armed by their
establishment.

We just need to push Am forms of PR indefinitely to force changes in the
dynamics of our country's politics.  I trust that the 2-parties ability to
push back will keep us from swinging too far to the use of PR.

dlw: Even if that's the case if neither major party can dominate a state's
politics then both will be changed in their policies and behavior for the

is ripe for such right now and it'd only need to succeed or come close to
succeeding once to make a difference.

dlw: IL's republican party had to be more dynamic or moderate than
elsewhere to compete.  It was abetted in this in that it had
representatives from all over the state and significant party primaries
from all over the state.  There was some third party representation at the
state level, but it was not great due to quasi-proportional nature of the
3-seat rule used.  The more significant fact is that other nearby states
that were/are economically dependent on IL could be more politically
independent of IL due to the inability of either major party to dominate
IL's politics.

The Prog party rose and fell with the fortunes of its leader Robert
LaFollette.  It changed the Democratic party and got shaken by the McCarthy
red scare.  If they'd used their political capital for the state use of PR,
they'd have likely had more staying power as a party.  As it is, third
party support is strong in WI still, relative to  other states.  We could
end up with a Green Democratic party there.

dlw: Power tends to corrupt.  Ideology loses its effectiveness as a glue
with larger groups, like with major and minor parties.  No matter what
parties say are their guiding principles, these will confound their
implementation.
This is why I prefer my "complex ecology".  If a change is needed then
we'll need folks willing to follow MLKjr and stick their necks out to move
the political center that the two major parties(of that moment) align
themselves around.

dlw: I agree that PR "works" in your country and elsewhere.  My view is an
analog to Pascal's wager: If multipartyism is the telos, we lose nothing in
the long-run from presuming that the US's going to continue to have a
two-party dominated system and picking our battles pragmatically so as not
to end this tendency in the short-run, but I have a hunch that my complex
ecology could prove to be both robust and good.

Outsiders, like myself, do deserve to be given a constructive role in the
US's system.  I trust that we will emulate MLKjr and Gandhi in this regard
much in the coming century, which will reduce the immediate pressure to
push for a multi-party system.  The two major parties will be "bearable"
for many more of us outsiders.

dlw: It might be better if we let FairVote keep face on IRV for
single-winner election rules and support them more so for their advocacy on
the use of multi-winner election rules?   This is my arg here that there's
not enough compelling evidence that Xoth>>Xirv to justify dickering over it
and potentially harming FairVote's cred among US progressives in the
process.

dlw: Even if it were a bubble then the kicker is to keep it inflating and
trust that it's successes will pave the way for additional innovations in
single-winner election reforms.  It's not easy to get a bubble going, it's
a lot easier to deflate it with a combo of obscurantism and perfectionism.
 If we support IRV (at least strategically) then it'll prove resistant to
reversals like in Burlington.  The combo of better understanding of it,
more unified support of it over FPTP by electoral reform advocates, its'
potential hybridization with Approval Voting and it being complemented by
PR will make it more resilient.

consequential outcomes may not work as well in other cases.   I expect
there'd be more such in the future.  I'm not against electoral
experimentation.  I accept that US politics is not the right place for such

dlw: And our disagreement is over how serious the perceived problems are.
 There's a path-dependency involved with advocating for electoral reform.
 It makes it easier to stick with rules that are closer to what's already
been pushed, even if there are perfectly good alternatives available.  As
such, given the transaction costs of advocating for any alternative to
IRV(and the consensus statement of this list-serve shows there isn't
consensus on what such would be), it's better for us to defuse our
analytical args that lower P_irv.

dlw: That's akin to fear-mongering.  IRV's marginal reversal at Burlington
was not simply due to its "inherent flaws" so much as a concerted attack on
it, abetted by snipes by electoral reformers who have invested themselves
in other alternatives to FPTP.   If more of us choose not to snipe at IRV
and instead focus on subverting the obfuscating args against it then the
momentum will continue and increase the scope for electoral experimentation
in t he US.

dlw: That would be good.  I'm betting they haven't faced a concerted attack
on the method, such as was faced in Burlington VT.   And I'd agree that the
Condorcet method is complex, especially when there isn't a CW, which
doesn't help with PCondorcet.  Similar could be said for a pure IRV, but
then I'd counter by suggesting my hybrid approach....

Like I've written above, the importance and scope of the US presidential
elections make it hard for a third party candidate to win.  These elections
in turn are important party-builders for the two major parties and tend to
fortify our two-party dominated system.  These pie graphs show how high is
the bar even when other election rules are used, which then tends to
mitigate the diffs in the relative value of the different election rules,
at least in the short-run for the US.

Once more, for the US, the results are not that different.   It is
inconsequential that Anderson would have come in 2nd, instead of Carter in
the other election rules.  There's no prize for coming in second place in
US presidential elections, at least not any more...

I agree that we aren't inherently two-party.  I promise to resent the two
major parties always.  I choose to accept this tendency in the US for the
near future, because I believe the two major parties can be reformed so as
to better house or accommodate the variety of voter preferences in the US.

only 3 candidates.  It's not hard to imagine something similar with 4
candidates.

dlw:  Like I said, it depends on the nature of the noise.  I figure it

their top candidate better than their 3rd and their 3rd better than their
7th favorite?

I  will admit that my intuition about a condorcet cycle probably was wrong.
 I was going off of how it's harder to get CW winners when there are ties
and so since non-ranked candidates are all tied it seems there'd be more
cycles.  At any rate, if only 3 rankings were allowed, it would lower the
diff in the value of IRV and Condorcet methods, since the latter's presumed
advantage is based on its use of all of the information.

dlw: I'm not sure the extent to which they're considering IRV3/AV3.  After
the counting of the statewide judicial vote in VA took 40+ days, I think
it'd naturally solve their problem and let them maintain their marketing
strategy.  It'd just be a short-cut to both make it easier to explain and
to get the final winner sooner.  As for me, I do not anticipate them
changing horses going in very different directions midstream.  I also think
most of the time the diff between the two would not be great.

sophisticated arguments whose links to reality are not easy to discern.
 One can concoct args that can go either way and at the end of the day, I
still think trying to determine the best single-winner election rule is
small potatoes relative to the need for experimenting with the right mix of
single and multi-winner (and hybrids thereof).

dlw: It's logically true that if you give more weight to the higher ranked
votes in determining the winner that you are less impacted by noise when
the incidence of noise is higher in lower ranked votes.  I don't need data
for that it's common sense.

It affects my attitude towards the concepts we use to discern about
reality.  I have commented on your real world examples above.  I still
think Pirv-Poth>>Xoth-Xirv in the short run in the US.

I'm employing critical realism to state why I think 3-5 seat (quasi) PR in
"more local" elections and IRV in "less local" elections (+ FairVote's NPV
for the presidency) is a winning platform for electoral reform in the USA.
My arg hinges on the need to choose election reforms that do not challenge
the US's tendency to have a two-party dominated system. I put most of my
money on pushing for American forms of PR, because my understanding of the
US's mucked up system is that the worst part of it is due to its tendency
to tilt to effective single-party rule and the resultant cut-throat
competition between the two major parties and because it's not hard for me
to imagine us having two rather different major parties whose duopoly
status is contested by minor parties and who are held accountable against
the influence of $peech by a host of small local third parties.

The effect of 3-seat quasi-PR in state legislatures has been demonstrated
in my country's history.  We already have third parties behaving like LTPs
or coalitions of LTPs.

As for IRV, I'm saying the above is so important and the tendency towards
having two major parties is so strong right now in the US that we can
afford to let go of trying to improve upon IRV beyond IRV3/AV3.  We can
make sure we have a more unified front to prevent further Burlington-like
reversals.  We can recognize that even if a multi-party system were better
than a souped up two-party system, not far from how I envision it, it's not
that much better and the latter is far more likely to be the next stage of
the evolution of the US's democracy.

So why not call a truce and trust that it'll be a lot easier to explore
other election rules once IRV3/AV3 has replaced FPTP in most single-winner
elections?

dlw: You're making it sound like the crux of my position is IRV and that
I'm a contortionist, fitting the evidence to my priors.  This is not the
case.  It doesn't mean a hill of beans that there are multi-parties in NY
under STV.  The fact is that third  parties are weak in the US.  They are
not our movers and shakers and so electoral reforms that cater to their
wishes are not in order.   So long as we improve the balance between
single-winner and multi-winner elections, their situation will be improved
upon.  And hopefully a significant change in which two major parties
dominate will make it so fewer people are severely alienated by them.

dlw: There aren't enough real world examples of the use of other
single-winner alternatives to IRV in important political elections to
justify the replacement of IRV with them as the status quo rule for
electoral reformers.  We gotta keep it simple.  Consider how little headway
the advocates of Score/Approval Voting have made among "normal people",
despite the amount of brain power put into their critique of IRV and
advocacy for AV/SV?  It's hard spade work to market election reform.  If we
were to try and start over again doing what FairVote has been doing over
quite a while, leaving aside how we'd settle which single single-winner
election rule we would push for, it would set election reform in the USA
back for too long.  I think it's much easier to see what we can learn from
Burlington to prevent similar reversals.

It's also a matter of logic wrt IL's example that it resulted in divided
gov't and a higher chance that the control of the state assembly would pass
between control of the two biggest parties.  This possibility forces
$peech-purveyors to hedge, which further evens the playing field in other
elections.  As such, I don't need a big dataset to verify it.  The result's
were strong enough in the relevant dimensions that the power was big even
with a small sample.

It's a lot harder to compare between single-winner elections, because the
different results are less pronounced most of the time and often not
consequential, like with Anderson beating Carter for 2nd place in the 1980
presidential election.

They didn't have a strong presidency elected regularly at the national
level that reinforced their two-party dominant system?

Ah yes, the concept of American exceptionalism has no currency
whatsoever....   The writers of the US constitution trusted George
Washington so much they gave the presidency a lot of powers.  This was an
exceptional circumstance(as was his declining not to become our dictator).
 This is why historically progress in the US has been associated with the
election of progressive presidents.  What I'm saying is that's dated, but
not irrelevant  Why not see our current strong US presidency as why we need
to focus on the use of American forms of PR in "more local" elections that
are rarely competitive in ways that keep the constituent-legislator
relationship that George Washington thought was important and mitigate the
cut-throat competition between parties that George Washington also feared?

Well, I think that given the resilience of the US's two party dominated
system in the short run that my answers make sense...  But you are right
that my arg is not founded on an electoral analytic argument.  It is
founded on my perception that if we gave a constructive role for third
parties that it could make our two-party dominated system function a lot
better(especially for minorities) and that such a less-is-more approach is
more fit for adoption in the US in the near future.
My args about the Ps and Xs of IRV relative to other single-winner election
rules have been ancillary to this reality-based argument.

I hope that is good enough for you for now.

WRT Jameson's arg:
KM: Yes. P_irv is currently greater than P_other. That is too bad. I think
P_irv is actually more like an economic bubble, because of the unappetizing
properties of P_irv. If we do nothing, then P_irv will at some point burst.
(That's what Jameson's wager is about).

JQ: My wager was that if there are more than 20 reforms in place in the US
10 years from now, over half of them will be non-IRV. Like any broad,
long-term wager, I'd be happy to win however; but actually, I didn't really
propose the wager because I think IRV will be implemented and repealed, or
even because I think that IRV will stop getting new implementations.
Rather, I think that it's entirely possible in 10 years for a new reform
proposal to outgrow IRV. I'm guessing that IRV is AltaVista or MySpace, and
that the Google or Facebook of voting reform is yet to get off the ground.

dlw: My hope was to win some of you all into becoming supporters of
IRV3/AV3 as that replacement so we can all put our oomph into supporting
FairVote's push for American forms of PR.  I think IRV3/AV3 could be
pitched by FairVote as essentially just like their standard IRV, with a
short-cut to simplify the explanation and to reduce the time it takes to
count the vote.  I would love to get others to join me in pushing for
FairVote to make this "less is more" adaptation.
