STV has been upheld as constitutional in the past, but the challenges were never brought over monotonicity failures. It's entirely possible a new challenge could overturn it; there's a strong argument that monotonicity failures violate due process and the equal protection clause.</div><div><br></div><div>The ideal case to bring to the Supreme Court would have been for Begich's campaign to sue after the 2022 Alaska election. A moderate Republican plaintiff is appealing to the mostly-Republican Supreme Court, without being too controversial.

The way to explain participation failures is to run a ton of ads explaining to Alaska Republicans that Begich lost because <i>he got</i> <i>too many votes. </i></div><div><br></div><div>One suggestion: why not rename monotonicity to "helpfulness?" (Voting should help your candidate, not hurt them). We can call monotonicity failures "spitefulness" (because the system is going out of its way to do the opposite of what you ask it to).</div><div></div></div></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Feb 28, 2024 at 11:32 AM Michael Ossipoff <<a href="mailto:email9648742@gmail.com" target="_blank">email9648742@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)"><div dir="auto">It’s surprising that participation-violation is unconstitutional in Germany, because, here, even Hare’s greater nonmonotonicity is okay.</div><div dir="auto"><br></div><div dir="auto">It’s disingenuous to say that Hare is nonmonotonic & Condorcet isn’t.
