So, our national polling average was at Biden +8.4 when the DNC began, peaked at Biden +9.3, and is now at Biden +7.2 after quite a few national polls overnight. You'd still like a couple more live-caller polls, but it should be a decently robust estimate. https://t.co/cy51vc5isJ https://t.co/thejXk0vJ0 — PolitiTweet.org
