Biden now +4.2 in our Pennsylvania polling average, which is now the same as in Florida (+4.2). These are the most common tipping-point states. By comparison, he's at +7.1 in our national average, so we see the same 3-point gap as in 2016. https://t.co/wKbW02AGO5 https://t.co/pGUrl77ncQ — PolitiTweet.org
