dlw: If it's only used for one branch and single-winner is used in the
other branches then you could say the undeserved advantage given 3rd
parties in the one is balanced b an undeserved advantage given to the major
parties in the other. What's more, this might be what is needed to tie
ourselves to the mast to do better by our ethnic/economic/ideological
minorities than we have historically in the US.

dlw: Only if we make a fetish out of nailing proportionality, like Germany
does. The more popular major party will have an advantage due to their
greater likelihood in winning 2(or 3) seats and the greater likelihood that
successful 3rd parties will tend to favor them, assuming that the larger
3rd parties ccome from the same side of the ideological spectrum as the
larger major party.
It will tend to work according to majority rule, but even still, it may be
necessary to have that uncertainty to protect minority rights. If the
bigger major party tends to control all branches it can leverage that to
dominate a state/country's politics. If they cannot guarantee their
control of one of the 2 branches then they cannot leverage as much, and
there will tend to be a more even playing field between the two major

Which would be a lot better than 100% domination and that's just the worse
case scenario... And since there'd be no limit on candidates per party,
there'd be room for intra-party rivalry that can be good too... The 2nd
republican won't be quite the same as the first, which is the point.

dlw: Yes, and unpredictability is part of what gets folks interested in
political elections. The odds are the bigger major party would win it,
especialy if the Droop quota is used.

dlw: I'm sorry I don't follow the logic of why 2-seat STV is better than
3-5 seat STV. If you can't get proportionality right then why bother

dlw: I believe the strategic use of PR is critical to handicap the
cut-throat competition between our two biggest parties that makes it so
hard for them to do anything together. I believe PR is necessary to make
some elections more likely to be competitive. I doubt that any
single-winner election rule will make a diff in a state-reps district
that's heavily skewed to favor a certain major party. And I believe 3rd
parties are essential to check the influence of $peech on both major
parties and to enforce its regulation via CFR.

dlw: How do you expect to do that, in the absence of more competitive
elections and better exit threat into 3rd parties?
We don't need a level playing field across all parties to make things work
a lot better in our 2-party system.

dlw:With the use of 3-5 seat STV with a droop quota it will still be hard
for 3rd parties to get into the US house of reps. If they did gain enuf
seats to make the current voting method not reliable then I'm confident
they'd change their method. It's that simple.
As for the state house of reps, I advocate the use of 3-seat LR Hare, but I
also advocate that at the beginning the parties choose their leadership and
then the reps all vote by plurality to put one party in power. That party
would get some extra procedural controls so its leaders can get things done
in the absence of a majority. But it'd be the 3rd party reps who would
decide which party is in power. And the ease with which a small 3rd party
can win that 3rd seat is what would make it hard for the leadership of the
party-in-power to use their controls to keep themselves in power

dlw: 3-5 seat quasi-PR for US house of reps and 3-seat PR for state reps
won't move us to a 3 party system. I also advocate for the use of an
approval voting enhanced form of IRV that also tends to maintain a 2-party
dominated system due to its "center squeeze problem" so I see myself as
trying to make our 2-party system more robust and dynamic, and to prevent
the onset of a 1-party dominated system, not unlike what recently existed
in Egypt with its nearly exclusive use of single-winner elections.

dlw: We used 3-seat quasi-PR in IL from 1870-1980. This forced the
puppeteers to hedge more and accept a relatively lower and more variable
return.... it also kept either party from dominating IL's politics, which
let other nearby states that were economically dependent on IL to have more
freedoms in their politics, which in turn spilled over to bring changes in
other states that were typically dominated by one party but feared change.
We have a successful model. It is the USA. The use of PR in "more local"
elections has an important trickle up effect that makes single-winner
elections in "less local" elections more meaningful. The UK is now doing
something like this and it led to their serious consideration of the use of
IRV. The point being that there is pressure to replace FPTP once 3rd
parties can gain sway via the use of quasi-PR or better in "more local"

I tend to take a more psychological view of the matter. We project our
tastes/preferences onto voters and design election rules that fit these
tastes/preferences. Or we get a vested interest in defending such a rule
and selectively value those characteristics that it has over others. It
doesn't have to be super-strong, but in the absence of any real money or
organizational imperatives, it's easy for those things to loom.

major effect. We were talking amongst single-winner election rules.

[sarcasm]That sounds realistic.[/sarcasm] You realize that the "approval
votes" are just the number of (up to 3) rankings a candidate receives? How
often do you think you can clone one of the other 2 and thereby shutout the
winner? I'd love to see an example of that. If the winner is preferred to
the top-2 ranked-vote getters then if they were cloned, it'd not be the
eventual winner who'd lose out on approval votes.

If you can give me a robust example of this, ie one that's not on a knife
edge, I will abandon the idea.
JQ tried to do this a while back for a slightly different matter and it was
very hard to do and he eventually agreed that it "worked", except for how
it tended to reenforce the 2-party domination thing that he believes (along
with others) is the bane of democracy.

I'm not worried about cloning non-winners.

dlw: de facto is based on the positioning of parties and determines what
issues are on the docket. True is what would be the case if every vote was
taken seriously by the system as a whole, but this in real life is really
dynamic and there could be some unintended consequences behind voting
methods that successfully always nailed the true political center.
Typically, it takes time to enact serious policy changes, hence the need
for a 2-party dominated system to provide the leadership required for

My arg has been that what is crucial is to change the mix of single-winner
and multi-winner elections and that in our system the diffs in quality
among single-winner rules is of 2nd order import. As such, it's best to go
with a tweaked version of the first-mover alternative to FPTP that's been
endorsed by the president of the USA and John McCain and many others, as
shown in Rob Richie's NYTIME article.

It's not hard to tabulate how many times a candidate gets ranked, so long
as you catch the cases where voters rank the same candidate twice or
what-not. That's easy to do.

It's not raw for a first stage of single-winner election. Plurality
at-large for multiple seats is not unlike single-winner elections, but
that's the point, it's a single-winner election rule.
thanks for the good comments.
