HELP!!! IRV vs Condorcet
- Recently some Greens and Libertarians have been involved in an email
dialogue regarding voting reform, specifically re: IRV vs Condorcet. It
is my understanding that the Libertarians officially support IRV, but
this local Libertarian group (or possibly a faction of the group) is
strongly opposed to supporting IRV. They have used information obtained
from the "election methods" website and email list to back up their
views. Can anyone point me to some information that will shed some
light on this debate? I believe the local greens would love to start a
coalition between groups that agree on election reform, but I'm
starting to think we are going to deadlock on this issue-- or agree to
disagree and move on...
- Dear Tommy,
the main problem of Condorcet methods is that there is no such thing
as "proportional representation by the Condorcet method". The main
argument of the Condorcet supporters against IRV is that IRV violates
monotonicity; however, there is no proportional preferential voting
method which has been proven to meet monotonicity.
Therefore, it is significantly more difficult to get from Condorcet
to proportional representation than to get from IRV to proportional
representation. This is true especially when one has switched from
IRV to Condorcet because of IRV's violation of monotonicity.

is even worse than plurality. Therefore, he opposes every IRV campaign.
In my opinion, this is rather short-sighted because most IRV supporters
consider the introduction of IRV to be only the first step of an
introduction of proportional representation.
