Nate Silver is the founding, or one of the original founders, of 538 - which has, I see, been acquired by ABC News. He’s a statistician of some repute, and competent; he’s pretty good at explaining and summarizing stats to non-math types. He’s gotten a lot of heat for forecasting results that were wrong, starting with the Clinton/Trump election in 2016, but if much of that is because people are terrible at understanding probability, and if you tell the average person something has an 80% chance of happening, they take it at a guarantee.
The issue is that 538 was pretty reliable at the start, but then something happened with polling and things started to go against predictions frequently enough that they sort of became just another voice - instead of a source you might use to bet on. The ABC acquisition probably didn’t help.
Anyway, I digress. Nate was the statistician face behind 538. I don’t know what he’s doing now.
