[EL] RCV in Maine and Third-Party Spoilers

Maybe I missed something, but you only get to your goal by ignoring the votes for the third place candidate when computing the majority, and thereby disfranchising all of those votes.
Put simply, you've got bad math.

Subject: Re: [EL] RCV in Maine and Third-Party Spoilers
Here’s a question about the Maine RCV election: Why do they eliminate two instead of just one at a time? Given how close the election was in Round 1 and the large vote for the losing candidate, you could have had (albeit very unlikely) Poliquin win with 51.7% of the vote if all of Hoar’s votes had transferred to him.
Granted, the probability of that happening in this situation approaches null, but you get the idea. Or am I missing something?
If they do check for that, or even if they don’t, it would be great to know how the votes transferred by each eliminated candidate instead of both together. I haven’t checked their other RCV races.
The table below is my arrangement of data from the Nov 26, 2018 file of certified results on the Maine SOS website. This means the totals are slightly larger than in Vladimir’s email, but the relationships are largely the same.

I thought Vlad's email offers an opportunity to think why sometimes voters "exhaust" ballots with ranked choice voting or don't come back for runoff elections -- with, on the latter, the average drop inf participation in federal congressional runoffs this year being 47% of the first round, with half the runoff winners in fact earning fewer votes in the runoff than they did in the first round.
Although it's perhaps fun to look at the new kid on the block (ranked choice voting), I thought i'd look at the old standards of runoffs through the eye of exhaustion - -specifically the Top Two elections in California this year.
See some numbers below that I generated from the California Secretary of State's website. As of Nov. 26, with votes still being tallied<https://urldefense.proofpoint.com/v2/url?u=https-3A__vote.sos.ca.gov_returns_governor&d=DwMGaQ&c=HUrdOLg_tCr0UMeDjWLBOM9lLDRpsndbROGxEKQRFzk&r=xr_OjwGHtP-zw6I-DJj_MQ4cusLbiVT1bScGa0c8ZJo&m=toVAec3-Hd1lH-6OfgFj2QG2wvva5-kmJj0jrp32VbI&s=4XOeQxhf0TSSUpky2UH4GkXicW7q7zmSroDzQAaIB0s&e=>. you'll see votes for governor (a Democrat-Republican runoff), Secretary of State (a Democrat-Republican runoff), and Lt. Governor (a Democrat-Democrat runoff).
My comparison isn't with the June preliminary round ("primary"), but within the same contest with voter reacting to the choices being offered to them. With the D-R runoff in statewide races, the dropoff from governor to those races is small. For Secretary of State, for example. it is only 1.53%. But for the D-D runoff for Lt. governor (and to a large, if lesser extent for US Senate), the dropoff is much bigger - 16.24% in the case of Lt. governor, or nearly 1.9 million votes.
If you think about who is likely dropping off, it's almost certainly Republicans. If you generously use the Cox vote in the governor's race as a the baseline for Republicans, that means that more than 40% of Republican voters likely skipped the Lt. Governor race -- they indicated a "pox on both your houses."
That is actually higher than the percentage of Maine independents who didn't indicate a Republican or Democrat as a backup preference. And I'm actually not surprised by that dropfff - there often is a core of third party and independent voters who really do think some version of "the lesser of 2 evils is still evil" or "don't encourage them with a vote."
So, then, the question is whether those voters are "spoilers" or really "abstainers." Are they fundamentally different than the some 40% of Maine's eligible voters who didn't vote at all? I'd suggest not. Just like those non-voters, they were "in play" for the candidates, and the candidates in fact did do enough to earn the votes of almost two-thirds of the independent candidate backers. The fact that they didn't earn the rest is something they'll need to reflect on, just like they need to reflect on not inspiring so many potential voters to get to the polls in the first place.
Speaking of runoffs as an alternative to RCV, I trust Vlad will keep an eye on the upcoming runoffs in Mississippi and Georgia. The Mississippi runoff turnout in the US Senate race may end up being pretty high , given the stakes -- we'll see. The Georgia turnout for next months' runoffs for secretary of state and another statewide office... not so much. You can be absolutely sure that a winner with RCV in the GA Secretary of State race this year would have won with a much larger number of votes than will end up being the case with runoffs.

Several things worth highlighting: (1) The “ballot exhaustion” rate was fairly low, about 2.8% of valid first-round votes; (2) the victor still did not win a majority of valid first-round votes; (3) by my calculation 35% (!) of voters who picked one of the independents as their #1 choice did not subsequently rank either the Democrat or Republican in a lower-ranked position.
I bring this up in response to the argument that RCV is a solution to the problem of third-party spoilers (who syphon off enough votes from one major-party candidate to lose him/her the election). Of course, all of those 35% may not have voted at all had the independent candidates not run; or perhaps they would’ve voted for Bond or Hoar even in the absence of RCV (assuming, of course, that Bond and Hoar would’ve still run had the election not been held under RCV…). But I thought this was worth flagging.
Note: This is not meant to be a general indictment of RCV or an argument that RCV is worse than the alternative.
