[EM] No. Condorcet and Hare do not share the same problem with computational complexity and process transparency.

To be clear, I am by no means a believer that IRV is the only reform worth
pursuing, or that it’s anywhere close to the perfect system.

Where Michael and I disagree is on the role of pragmatism. I believe that
any time an alternative to plurality voting is on the ballot, voters should
support it. I think the folks in Eugene, Oregon, should vote yes on STAR. I
think more places should try out approval. Beyond those three, I read this
list because I enjoy learning about completely new and different systems
that would be fascinating to see in practice somewhere one day. But in a
place where citizens are asked for an up or down vote on IRV vs. FPTP, I
don’t see how you can defend voting for the worst possible system because
the proposed reform isn’t exactly what you’d like.
