Indeed, 538’s model showed ~50 out of 100 wins for either side, when running simulations. But that doesn’t mean that they were predicting a 50/50 split, a significant number of simulation results showed a large vote margin for one side, it was just equally likely which side it would be.
Although I don’t actually think it was equally likely like that, we are missing something to make all this analysis actually informative rather than a “all I know is that I don’t know anything”. We had mountains of evidence indicating that it was totally unclear, so frustrating. Perhaps that’s how the probabilities actually were, but somehow guts pointed to Trump much more regardless of personal bias, and in hindsight it feels rather obvious. Confirmation bias I guess, I still want trust all the expert analysis.
