Yes but these are definitely hypotheses. Fivethirtyeight has extensively covered it. In 2016 they covered it a lot, did a post-mortem on the election, and said the industry said they’ll fix it for next time, then in 2020 we got even worse polling errors.
I miss Nate from the fivethirtyeight days. It’s sad to see his model paywalled.
Random but if you’re a polling nerd this site is a godsend: https://swingstates.vercel.app/
its based on the 538 API, they also have a mastodon and bsky bot
This cycle a lot of polling has oversamples GOP. And they are using a new technique wherein they weight polls based on previous vote. Which is interesting I guess. Anyways, we’ll see what happens in a week.
As deserved. The pony handouts aren’t going to happen by themselves.
