I was mostly just pointing out that IRV isn’t a panacea, you can still get a vote splitting like effect. Interestingly, IRV also has the property that sometimes the simple act of voting your true preference *at all* can cause your true preference to lose, and sometimes you would have been better off not voting at all.</div><div><br class=""></div><div>I’m struggling to find a resource besides that doesn’t also include shilling for another voting system or isn’t a lengthy paper but <a href="https://rangevoting.org/IRVpartic.html" class="">https://rangevoting.org/IRVpartic.html</a> gives an example and <a href="https://rangevoting.org/TarrIrv.html" class="">https://rangevoting.org/TarrIrv.html</a> is a more complex example.</div><div><br class=""></div><div><br class=""></div></body></html>
