The only place in the US that uses IRV is SF. I think it will be
used for the first time this fall. In SF, the election is
non-partisan. It is replacing an election+runoff system. If
no candidate got a majority in the first round, then there would be
runoff between the top two.<br><br>
There are often more than two strong candidates. Here are the
results from the first election for last year:<br><br>
<pre>GAVIN NEWSOM . . . . . .
. . . 87,196 41.92
MATT GONZALEZ . . . . . . .
. . 40,714 19.57
ANGELA ALIOTO . . . . . . .
. . 33,446 16.08
TOM AMMIANO. . . . . . .
. . . 21,452 10.31
SUSAN LEAL . . . . . . .
. . . 17,641 8.48
TONY RIBERA. . . . . . .
. . . 5,015 2.41
</pre>The runoff between Newsom and Gonzalez was quite close.<br><br>
In Cambridge, MA they use STV for city elections. These are also
non-partisan. I don't think there are any other ranked ballot
elections in the US.<br><br>
I imagine you know this already, but IRV/STV is used in Ireland, London,
Malta, Australia, and New Zealand. I might be missing a few
others.<br><br>

Subject: [EM] IRV - how many candidates per party?<br><br>
There are several IRV experts on the list. I am sure you are aware of
=<br>
its practical use, too.<br><br>
I'd like to know, how many candidates are usually offered by the same
=<br>
party in IRV? Only one? Two or more?=20<br><br>
IRV is used in San Francisco and some other places. Since US has =<br>
two-party system, offering only one candidate per party makes the total
=<br>
of two candidates. If there are two candidates, there is no difference
=<br>
between FPTP and IRV, right?<br><br>
Does anyone know of any empirical study of practical use of IRV? Any
=<br>
comment is welcome.</blockquote><br>
<blockquote type=cite class=cite cite>I should add a question to the post
below: Is IRV in San Francisco and =<br>
other places used to replace primaries+general election or is it used
=<br>
only for general elections while primaries take place at some other time
=<br>
earlier?</blockquote></body>
