2022 was a great cycle for polling.

Below average error for all levels of national races. Likewise polling bias was generally below average.

Among the best pollsters in the Midterms: New York Times/Siena with an average error of 1.9% and a bias of 0%. The Times called 88% of races correctly.

Among the worst pollsters: Trafalgar with an average error of 5.3% and Republican bias of 4.9%! Trafalgar only called 62% of races correctly. What's even worse is Trafalgar had 37 polls that cycle, far above most other pollsters and second most among all pollsters. So one of the worst performing pollsters in 2022 flooded the polls.
