I mean and they were wrong in many places. The polls for the Senate were terrible. Races that were predicted to be tight wins for Democrats were big wins for Republican, and a fukking dead Republican won a seat, I believe.
They had Biden up in Wisconsin by 17 and 11 points, per the NY Times and WaPost respectively. The NY Times predicted that adjusting fog 2016 margins of error, that Biden would either win Florida or basically tie it up, and he lost it by about 4 points.
The polls got the outcome right, but the margins of victory in many states were much closer than what the polls predicted.
