Here, for instance, are House Effects by 538 pollster rating (where 0 is their "A+" and 1 is an "D-") As you can see, there's a decent relationship between pollster quality and a Biden House Effect. The small number of A+ polls means they can't anchor the adjustment. https://t.co/5Cu9D19DLu — PolitiTweet.org
