Will I win my bet against David about polling errors in MI/WI/PA?

74%
chance

The terms of the bet are such:

I have staked 25k mana against David's (@dlin007) 90k mana.

David wins the bet if Trump outperforms his final (morning of election day) RCP polling averages (Trump vote share, not margin) in all three of MI, WI, and PA, and does so by an average of at least 2.5%. I win otherwise.

TLDR: therefore, what you're betting on in this market is the outcome of this bet; resolves YES if I win (Trump doesn't significantly outperform) and NO if David wins (Trump significantly outperforms).

@Joshua @SemioticRivalry and @shankypanky are arbitrating and provided escrow.

I MAY bet in this market. If the resolution is at all controversial, then the team of 3 mods listed above will determine the resolution! If they decide to resolve the bet to some PROB or cancel it, then this market will resolve accordingly (although I really don't see why or how that would happen). I would ask those 3 mods to therefore not bet in this market to avoid the appearance of impropriety!

I've set the close date well after the election in case it comes down to a recount or something stupid, but hopefully this should resolve shortly after the election (as soon as the bet resolves itself).

lol RCP, ben you get a free win

@nikki it’s like within 0.5 points of Silver Bulletin I’m p sure

@nikki I mean currently there's a 0.2% difference between RCP and Silver Bulletin in PA, 0.6 in WI, and 0.5 in MI, and I'd expect those to narrow as we get closer to election because RCP is pure polling and Silver Bulletin is modeling predicted final vote share

@benshindel RCP is a hack poll aggregator, not "pure polling"

They make stupid assumptions like polling error being correlated across years

@nikki I’m not trying to defend them tbh, but I do think they’re quite in line with other polling aggregators this cycle

@dlin007 The 2 candidate average doesn't still sum to 100 or even 98/99. The actual third party should be lower than polled, and undecided voters will split. I'm curious why this bet is determined based on vote share but not Trump - Harris margin?

@PlainBG yeah, my original idea was for Trump to beat the margin, but it was misunderstood by Ben which we discovered well into the whole thing, so this was the compromise

@PlainBG @dlin007 well, in 2016 and 2020 there was about 5% and 2% third party votes, so I’m not sure the final RCP vote share will be that too far off from that!

Currently in swing states in the RCP average it appears that there’s less than 5% who aren’t either Trump or Harris.

But this phenomenon should benefit David, since it implies both candidates should slightly out-perform their final RCP average. However, the two-way margin is more swingy (as taking off 1% from Harris and giving that to Trump, for example, would lead to a 2% swing towards Trump) and this would benefit me in the bet. However it’s not entirely that simple, as turnout is also a factor, and some ppl who would’ve voted for one candidate might just not vote. All in all I think it’s close to a wash but might benefit me slightly, which is why I was willing to adjust the odds from 4:1 to 3.6:1

opened a Ṁ500 YES at 62% order

Makes sense. Another factor in Ben's favor is RCP polling averages include partisan polls without making adjustment and they historically skewed more Republican.

3.6:1 still seems quite aggressive and would be closer to my upper bound

fyi this would have resolved NO somewhat comfortable in 2020 and decisively in 2016

opened a Ṁ1,000 NO at 60% order

Limit order for NO up at 60% for whomever wants it!

@dlin007 why did you take this bet? You could've gotten a better price for a more likely outcome by just betting that Trump would win the election on one of the main markets.

bought Ṁ50 NO

@Nightsquared this was the origin of the bet: https://manifold.markets/jack/who-will-win-the-2024-us-presidenti-8c1c8b2f8964?tab=comments&play=true#k8g5v154uv

it was more of an expression of confidence in my thesis that pollsters still have (predictable) systemic issues polling Trump among WWC. My original idea was about the final margin, which has happened in both elections but still quite confident about this though

opened a Ṁ1,000 YES at 43% order

@dlin007 in any case, I put up 5k in limit orders if you want to bet more on this
