<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Since IRV starts with first-place choices and works its way down, any candidates not ranked on a particular ballot get treated as bottom-ranked by default, so
I don’t think it was a problem that they didn’t mention it. But for Condorcet spelling out what happens in that situation may be warranted.<o:p></o:p></span></p>

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.<o:p></o:p></span></p>

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.<o:p></o:p></span></p>
