House remains a very very likely Dem flip, with anything from 220 to 260 seats inside the 95% uncertainty interval for normal error in polling and fundamentals models

Not Elliott, but in our sims a single Senate race's margin swings about 7 points from night to night, and the part all races share is about 4. So close races tend to break the same way, just not in lockstep.

I've noticed with the lack of any polling, the senate odds tick towards Republicans in the toss-ups generally. Is that just a function of the existing polling just being farther away from present day and fundamentals making a bigger difference?

Ours barely noticed over the same two weeks: 50.9 to 51.0 expected Democratic-aligned seats, and 54 to 56 in 100 for control. Is your half point coming from a couple of races or spread across the map?

I've noticed a number of right-leaning polls in the Fifty Plus One averages. Insider Advantage, Trafalgar, etc. Is that influencing the polling averages from what the more credible pollsters are showing?

Thanks. I remain a polling skeptic. Some of these polls are such small samples. There's no way 400-1000 surveys can be statistically representative of a state. Then you throw them all into averages and weight them and predict who is likely to turnout. It's just hard for me to believe.

Sample size is the smaller problem. A clean random sample of 600 lands within about 4 points of the truth 95% of the time. The hard part is that the people who pick up aren't random, and no sample size fixes that. That's the error a forecast has to leave room for.
