Summary
Polling aggregator FiveThirtyEight has named Vice President Kamala Harris as the narrow favorite to win the presidential race on Election Day, shifting from former President Donald Trump for the first time since October 17.
Harris’s lead is razor-thin, with FiveThirtyEight’s model showing her winning 50 out of 100 simulations compared to Trump’s 49. Similarly, Nate Silver’s model in The Silver Bulletin also slightly favors Harris, giving her a win in 50.015% of cases.
Both forecasts emphasize the unprecedented closeness of this race, with Pennsylvania as a key battleground.
.
Also, these models are extremely rough. They are forced to make a bunch of very rough estimations and guesses, which are then aggregated to a stupidly precise number making it look scientific.
It’s a fun enough exercise, but it’s really just repeated endlessly because it’s so goddamn easy to report on.
There’s also the problem that if the polls are crap, the results of the model will also be crap, regardless of how accurate the model is. It’s similar to how publication bias affects meta-analyses. Several analysts have already argued that pollsters are unlikely to underestimate Trump again, and may in fact over-correct and underestimate Harris much like how they underestimated dems in 2022:

The Nate Silver model (at least) puts in a bunch of “corrections” for poll quality and historical bias from individual pollsters.
So you’re really playing a second or third level game of “Did Nate (or your other poll aggregator) correct for all the effects and biases, or did they miss something important?”
And we will never be able to validate if these odds are accurate or not, because this specific election will never be replayed again.
if the early voter demographics + recent polls only have it at a ‘coin flip’ as the polls open on the last day:
we’re screwed.
(please go vote and prove me wrong)
I’m not sure how accurate early voter demographics correlate to voting patterns anymore. I work for a municipality, and my office has a clear view of the voting lines. They were PACKED for the first week of early voting. They have been empty today. Like, people are still coming in to vote, but it’s onesie-twosies, not the 50+ person lines it was. Allegedly we had over 50% of our eligible voters cast their ballots during early voting. And my area is pretty solidly red. I’m having trouble making any sort of prediction based on it.
Nate said today that a coin actually has a 50.5% chance of heads, so this is technically closer than a coin flip!
Pollsters sucked in the election. It’s like forecasting a 50% chance of rain. “One candidate may win, but the other may win too!” I know that.
That’s pretty much always what the polls say for the presidential election. I don’t know why people expect pollsters to have crystal balls. The election is mostly decided on who is going to actually go vote, and a lot of people don’t know the answer to that until election day.
And even if they did predict anything convincingly, it would probably end up a self-defeatung prophecy, as people don’t care to show up. Or self-fulfilling, if people want to vote for the winning team. In either case it’s just very limited what polls can achieve.
Ideally, your vote shouldn’t depend on what you’re told by pollsters
Well, if anything was ideal, this whole situation would look very different.
It’s Newsweek, and Newsweek is a bit ratch, as publications go.
This is why people keep complaining about the polls being wrong. The polls are often pretty good these days, but the people reporting and talking about them do not understand basic statistics.
If I had a coin with a small booger weighting one side and making it more likely to land booger side down 51% of the time, would I be surprised if it landed booger side up? No.
Doesn’t matter. Get off the couch. Vote.
Bring your friends.
Everyone’s been talking to grandma this cycle. The grandmas are out in force.
Respect granny and go do the same.
I voted almost a whole month ago mostly from the comfort of my couch, thank you very much.
I vote for you to lick my ball sack.
Because you’re unable to wash it properly yourself?
I cannot wait to stop seeing this comment. “Doesn’t matter. Go vote.” Like people on Lemmy or even reddit for that matter are unaware of the impact of voting.
Doesn’t matter. Go vote.
Thanks for that worthwhile contribution. You really changed my mind.

This aged well /s
Like fine milk.
This was one of the last things I read before going to sleep. I thought it might be true.
That aged well

The headline is misleading.
Out of 80,000 simulations, Harris won in 50.015 percent of cases, while Trump won in 49.65 percent of cases, per Silver’s model. Some 270 simulations resulted in a 269-269 Electoral College tie.
So a better headline would be “Simulations show Harris and Trump are equally likely to win the election.” The difference between them is insignificant.
And when you factor in all the underhand cheating tactics the Republicans have up their sleeve, the Democrats’ tendency to cave, and the Supreme Court’s bias, Trump looks a lot more likely to win than Harris.
So a better headline would be “Simulations show a high likelihood of political violence and another SCOTUS stolen election a la 2000”.
Please flush the Orange Turd.

Yes, and no. They estimated a slightly higher chance for a Hillary win over a Donald win, but they were well within the margin of polling error, and they have been for every election. Plus people have a tendency of over-valuing a “51% chance to win”.
While this is good news, it could mean nothing.
EDIT: 538 explained it better than I ever could:
"Statistically, too, there is no meaningful difference between a 50-in-100 chance and a 49-in-100 chance. Small changes in the available polling data or settings of our model could easily change a 50-in-100 edge to 51-in-100 or 49-in-100. That’s all to say that our overall characterization of the race is more important than the precise probability — or which candidate is technically ahead.”I predict someone will win this election.
Yes; pollsters and advertising platforms. They’ve got to be raking it in these days.
Someone will win, but the rest of us might lose, bigly.
More people should play xcom, with a 51% chance i would assume to miss 2 from 3 shots
Anyone who’s ever played a dice-based game knows full well how uncertain 50% is.
Warhammer: oh I just need a 4+ to hit, this shouldn’t be bad - proceeds to roll nothing but 2s
DnD: I just need an 11 to hit, surely I’ll get him this turn - fails, rerolls a fail into another fail
Every time you need it, a coinflip will fail you
I played a lot of D&D back in the day, and while I’m normally not a superstitious person, we did have a dice jail for poorly performing dice. That light blue d20 was a repeat offender.
Fuck the forecast and Vote!
I wouldn’t be surprised if what we learn from this election is how it wasn’t really close at all, and all of the polls were extremely wrong.
I’m basing this on the fact that more newly registered voters are voting this election than in decades, and all of the polls only account for “likely voters“ based on their registration and party affiliation without taking into account all of the new voters. Most of the new voters are likely to vote Democratic.
There have been a few articles on “herding” which I didn’t even know about before this election. I am no pollster, but it sounds like there’s a huge incentive to protect the reputation of the polling firm (“it’s a draw, so we can’t be wrong”) vs reporting numbers they think might make news.
Looks like basically every new voter was Republican
Every poll is a lie.
Vote!
50.015% literally means that neither candidate is favored to win. Take out a coin, assign Harris as heads and trump as tails, now flip the coin a bunch of times - and that’s exactly how often Harris or trump is likely to win the election
EDIT
Nate Silver just posted his final pre-election blog post and he explains very clearly that this is a dead even race. Either candidate is just as likely to win as the other candidate.
https://www.natesilver.net/p/a-random-number-generator-determined
I heard that Nate was also being critical of pollsters who were “herding” their results to not get caught too far on the wrong side, and yet he’s doing it. I’m just going to watch the results come in and not worry about trying to predict the future that will be known soon enough.
The only good thing with all these “tied” poll reports is that it may encourage voting to break a perceived tie. So vote like it’s tied, and hope for a blowout.
He’s not doing anything. His model is setup many months before the election, and then it stays completely unchanged until the election is over. He doesn’t do any polling, he just runs his pre-set simulation model on the data that the pollsters release
His model and 538s have both produced outcomes where one candidate gets 520+ EVs.
He assigns the quality ratings to polls himself and publicly announces them. They’re based on whether or not they predicted the outcome of the election.
It’s his very poll scoring system that causes polls to herd. Because even if they’re wrong, they’re wrong together.
He determines the weights of those polls and chooses how to apply them.
Nate has done plenty.
Americans have made it clear that will never elect a woman. This election was a mandate against women
You can’t spell President without P e n i s
I doubt it’s never (assuming we last much longer as a democracy). It’s just not soon.
Yea probably
I dont care what the polls say. I voted, you should vote, tell your friends and family to vote. Tell the stranger down the street you barely know to vote.
The safest prediction of 50/50. No matter who wins they can claim to have called it.
The Nate Silver special!
Polls be dammed. If Kamala doesn’t win a significant victory today, I’ll be shocked and my faith in humanity will be shaken. Again.
