Nevada, Ohio, Georgia, Arizona, Wisconsin, North Carolina and Penn are really the only competitive races. All those races may be decided by 2% or less. Everything else probably won't be close.
And there is zero excuse this time around for Republicans not to be prepared. They've seen the playbook. They know where the competitive districts are and where they need to be focused. They should have poll watchers at every balloting location in these districts and an army of lawyers sitting on go ready to file lawsuits if necessary. Good lawyers. If they let any improprieties happen again they might as well disband the Party and start over.

There's almost no scenario in which Republicans can gain 40 seats in the House (a minimum) and lose the Senate. They may not pick up as many in the Senate relative to the House, but actually losing it is nearly impossible. That would almost require significant portions of R House and D Senate voting on ballots, including areas where the R senate candidate should be a lock.

A significant portion of the democrat party does not vote in mid-terms.

It wouldn't, however, be a bad idea to set up camp-outs at drop off ballot locations starting in October to video tape late night ballot stuffing. Might deter mules. At least get the word out that people will do that. I'll sign up for a shift or 2.

Focus on what we need to focus on and we will be fine. If we don't, as somebody said earlier, we have a penchant for snatching defeat out of the jaws of victory.
Peace for Ukraine!

This is right. We need more R poll watchers and more fear of persecution when commuting malfeasance

Edit: this is more in line with the reason Oz or Walker will lose mail ins

In the contested districts, they need to have a poll watcher, an armed PI , and an attorney at each location at all times. They pay millions and millions for ads. They could afford to pay a few million dollars to try to have an actual election.

Our elections are still being manipulated and outcomes changed.

538 knows that and counts on it.
I'll disagree with both statements, but I'm also curious why you claim the second one. Their methodology is all poll algorithms.
plus ça change, plus c'est la même chose

Don't they just use polling data, none of which is very accurate 100 days from state elections where most people still don't know the candidates and there's a large number of undecided voters? Either way, Walker and Oz would vote with the Rs and that's better than voting with the Ds.

538 was laughably wrong in 2016. That site is run by an Obama fanboy and is about as trustworthy as a (D) push poll

Of course they'd vote with the Rs if they win

I don't think they'll win

They gave Trump a 28.6% chance of winning. That's not insignificant, the results were within 1% in several states

In Georgia now, all drop boxes are inside and only open during daylight hours with a camera.

This is some absolutely disgusting s*** right here....Kemp and the GOP are so gross in Georgia by trying to suppress the vote of those who identify as members of the CBVONC+ (Cats, Bats, Vampires, Other Nocturnal Creatures) Community!

This is Van Helsing 2.0 and can't be tolerated!!

If a meteorologist says there's a 70% chance of rain and it doesn't rain, he's not necessarily a bad forecaster.. If it rains every time he says there's a 70% chance, he is a bad forecaster. The difference is, and how forecasting is ultimately measured, is in how well your forecasts match up with outcomes over time. The meteorologist is good (actually more like fantastic) if his 70% predictions result in rain 70% of the time, his 30% predictions result in rain 30% of the time, and so forth.

In the case of his 70% forecast, if it doesn't rain, he isn't wrong per se. There's still a 30% chance it does not rain, and even if he gives you a 70% chance, he's not saying it will rain or that there is a guarantee even though the probability of rain is greater than the probability of no rain. You may interpret it that way, but that isn't the meaning of the forecast.

If you do view his forecasts in binary or classification terms, either it will or it will not rain, he is "wrong" quite a bit. Let's say he makes 100 forecasts, 50 times he predicts a 70% chance and the other 50 he predicts a 30% chance. He is an excellent forecaster, and those predictions are accurate over the 100 forecasts. 70% of the 70% predictions have rain, and 30% of the 30% predictions have rain. That said, you view those 30% no rain and 30% rain outcomes as "wrong" because the lower probability turned out to be correct. So he's "wrong" on 30 forecasts out of 100, but that doesn't make him a bad forecaster.


Dice are another example. There are known and calculable probabilities for rolling dice. If you roll 2 dice, I say you have an 83% chance of not rolling a double, and you roll a double six, I'm not wrong. The math says so, and your rolling of a double does not disprove that fact. You still had a 17% chance of rolling a double. Rolling three doubles in a row has about a .5% chance of happening, but even at those low odds it still has a pretty good chance of happening if you roll long enough.


When making point or regression forecasts, you include a confidence interval (think the probability cone for hurricane tracks). The actual value of the outcome should fall within the interval for the given confidence percentage (95% of the time for a 95% interval). As long as that remains true, you aren't wrong on the 5% of instances when the actual value falls outside the interval. If it falls outside more or less often over a long enough time, then and only then are you "wrong" and do you need to revisit your forecast. If it falls outside too much, then what you think the variance between outcomes is is probably too low. If it falls within too much, then the variance is likely smaller and you can tighten the interval to make the forecast more useful.


When it comes to 538's political forecasts, they make probability estimates based on many different polls and they're historical accuracy on vote totals to determine election outcomes. These have confidence intervals. They actually do pretty well at this, and the votes fall in line with what you would statistically expect with a frequency you would statistically expect based on those confidence intervals.

Lots here line to say they whiffed on the 2016 election because Trump won and they only gave him a 28% chance, but that is analysis of wrong. Trumps chances were based on the probabilities for individual states, and he needed to win in several tight state races where he wasn't favored to win the EC. Conditionally, those individual state race odds multiply if they all need to happen together, so his odds were actually low. However, he still had chances to win each one, and he did. In each case, the outcome was within the confidence interval and margin of error.

Some people here will call this "hedging," but it is not. Hedging involves making a second bet or prediction opposite another to limit exposure or to secure winnings based on new/different odds. Forecasting or predicting a range of outcomes is just statistics. The measure of how good you are is how often your ranges are correct in regards to how confident you are. 538 is actually pretty good about this.
