Doesn't fivethirtyeight ban their polls? This site should too.
538 upgraded them after 2020 given their relatively accuracy. They are now an A-. Their polls are suspect, but they have a decent record of success at this point. Some huge misses in the Sunbelt in 2018, but they were closer than most of the gold-standard firms in most other regions 2016-2020. I assume their success will dry up if gold-standards ever stop underestimating the GOP, because it often seems that they use ad-hoc adjustments to give good results to Republicans.
