This is an old ppt slide from May 2020, showing the apparent shift in early '20 polling v. the poll bias in '16. The warning signs were there from the start (inspiring the 'if polls are wrong' table). Also notice the same pattern in '18, tho the polls weren't biased on *average* https://t.co/zMyqGTaSVD — PolitiTweet.org
