Alright. Here is my attempt to write the simplest possible Condorcet
language in legalese. This here is 126 words, which is a fair bit shorter
than the 169 words of the IRV template:

All elections of mayor, city councilors and school commissioners shall be
by ballot, using a system of ranked choice voting without a separate runoff
election. The chief administrative officer shall implement a ranked choice
voting protocol according to these guidelines:
 (1) The ballot shall give voters the option of ranking candidates in order
of preference.
 (2) A candidate “A” is said to win against another candidate “B” if more
voters rank “A” above “B” than rank “B” above “A”. If there is a candidate
that wins against every other candidate, that candidate is elected.
 (3) If there is no such candidate, then the candidate with the most
first-choice votes wins.
 (4) The city council may adopt additional regulations consistent with this
subsection to implement these standards.

I think anyone would agree that this is much simpler than the IRV language.
Part (1) is lifted straight from the IRV language. Part (2) is the
Condorcet rule in the simplest language I could think of and I think it's
drastically simpler than IRV. You said you didn't want to synthesize any
particular Condorcet method, but I felt I had to include a way to deal with
cycles, so that's part (3). The rule I wrote is FPTP which isn't great but
it's easy to understand and familiar.

Basically, the method is "elect the Condorcet winner if there is one,
otherwise do FPTP". That's the dumbest Condorcet method, but it *is* a
Condorcet method. Let me know what you think. I can try to come up with
another option for (3) if you want. Just try to give me an idea of where
you want to strike the balance between simplicity vs having a good rule for
resolving cycles.
