so Terry, in 2009 Burlington, did 495 of 1513 voters that marked their
ballots as W>M>K (perhaps with some other candidates in between)
experience LNH? not so much to their first choice, but to their 2nd
choice? how is that different from a Nader voter in 2000 who might
tolerate President Gore who actually caused W's election? Keri told
us in that debate that such a thing couldn't happen with IRV, did she
actually do her research?

i don't think anywhere close to a comparable effort has been given to
that reform. even with your help (and i know you were trying to lay
low because you were most often cited personally for bringing IRV to
Burlington), i felt pretty alone.

the Range/Approval guys just don't seem to get the *inherent* pressure
to tactical voting that either Range or Approval causes. i dunno why
they can't see it, it's obvious to me. anyone who wants to maximize
their electoral influence (and who that bothers to vote doesn't?) will
push the score of the candidate they really support to the maximum or
approve only that candidate (lest they worry about harming that
candidate by scoring or approving other candidates) and the method
will devolve into FPTP with a scaling factor. it obviously will cause
voters to agonize over exactly what tactics they bring to the polls.
i respect Warren's analysis of the 2009 Burlington election, but he
hasn't gotten me past square 1 in his selling of Range or Approval. i
just don't buy the premises. simply because of the nature of the
ballot, it causes tactical concern for any voter who is thinking with
any depth in an election with multiple viable candidates.
the existing establishment of STV in many jurisdictions is not much of
an asset, because it hasn't always worked so well in those 100 years.
IRV is like selling a not-very-good upgrade to a crappy operating
system. people are dealing with all the frustration of MS-DOS for
years and Billy Gates then comes with his bloated and buggy Windoze as
the solution to all of our MS-DOS woes, some adopt it and find out
later that it also is a POS. the problem with FairVotes promotion of
IRV is that the failures of IRV will sully, by association, the ranked
ballot because too many dumb people cannot (because of FairVote's
promotion) differentiate between the ranked ballot and the STV method
of tabulating it. that was the big mistake from the very beginning.

i suggest that it was used as an excuse, a ruse, to discredit the
adoption of IRV over the FPTP/TRR that existed before. we both know
that it was completely disingenuous for the IRV opponents to point to
the 2009 election and accuse it of "thwarted majority" because the
method they were dragging us back to would not elect the unambiguous
majority winner either. if fact the method they took us back to
totally obscures that information because the "Vote for One" ballot
will not even collect sufficient information for us to even know who
had the majority support over any other candidate.

there were *many* Dems that were against IRV in Burlington (mostly
also from Wards 4 & 7). some i worked side-by-side with in Howard
Dean's prez campaign. if it were not for those Dems, IRV would have
survived this year (since it was so close). and it was also because
of such poor turnout from the other more liberal wards.

not likely. in 2006 he was the CW (and also the plurality winner).
there wasn't as much of a fuss then (but there was some).
*but* if Condorcet was the law and the "3rd place" candidate (who was
the CW), i believe also there would have been a big fuss. but they
couldn't have disingenuously used the "Thwarted Majority" critique as
they did this year. and far fewer Democrats would have jumped on the
"Keep Voting Simple" bandwagon. i don't think the repeal effort would
have succeeded since it was already so close.

that is true. but when IRV fails to elect the CW, we know there are
other pathologies that pop up because of that. it's *because* in 2009
the CW was kept out of the final round that the IIA effect ("Spoiler-
lite"), LNH-lite effect (which punishes non-tactical voting), non-
monotonicity effect all occurred in that election. if it was
Condorcet in Burlington in 2009, they couldn't have made any of those
arguments nor the precinct non-summable criticism. *all* they could
argue was that their plurality (of 1st choice votes) winner was not
elected.
so if we're gonna improve the operating system, let's really improve
it. because if we bring a so-called improvement and it causes the
computer to crash, people will want to go back to their tried-and-true
command-line DOS and be very wary of later proposals to improve it,
even if the later proposals really *do* improve it.

i do too.

but, by promoting IRV as synonymous with Preferential Voting
(essentially as the only manner a government can tabulate the ranked-
order ballot) and denying the carnage when it crashes, FairVote ends
up undercutting all reform efforts.

remember, the problem (with IRV) is *who* gets to be those two
finalists. there is a problem with saying that Bob Kiss is *the*
majority winner when, in fact, a majority of voters agreed that Andy
Montroll was the preferred candidate over Kiss. but, because there
was no cycle, the same cannot be said about Montroll. in every case,
in every pairing, Montroll is the majority preferred candidate. there
is no sense where Montroll is *not* the majority. this lack of
ambiguity cannot, of course, be claimed if there is a cycle. that,
and only that, is the weakness of Condorcet. but if there is no
cycle, there is *no* sense that anyone other than the CW can make an
unambiguous claim to the majority mandate.

the problem is if it's the *correct* two candidates. Condorcet gives
*every* pair of candidates an equal standing whereas IRV will ignore
some defeats in a similar (but less flagrant) manner that FPTP ignores
some salient defeats. *every* pairwise defeat should be considered,
not just some, not just one.

and that concept, while "traditional" has always been flawed, for TRR
or for IRV. the *whole* problem with runoffs, whether they're
"traditional" or instant, is the problem of determining who belongs in
the runoff. saying it's the top two 1st-choice vote getters is a
contrived criterion. more information of voter preference needs to be
collected.

at some point, we have to stop justifying the use of the SUBstandard,
just because "everybody else is using it".

not "ALSO". that is the falsehood, Terry. if there is a CW and IRV
(or any other method) misses in electing that CW, then Condorcet
*exclusively* finds the unambiguous majority winner. Bob Kiss was not
the majority winner even though a majority of voters preferred him
over Kurt Wright. A majority of voters also preferred Andy Montroll
over Kurt Wright, so Bob and Andy stand on equal ground in that manner
(actually they don't since Andy's preference over Wright was more than
3 times greater than Bob's). So then the question becomes of course
who, between Montroll and Kiss, did the majority of voters prefer?
Montroll exclusively had the *unambiguous* majority standing with
voter preference.

that was my ward, too. the first-round majority winner was only 6
votes ahead of the "loser" who eventually became the winner in the
runoff.
i'm getting tired, Terry. i'll bow out at this point.
