Right now, for instance, Biden is up 10 points in MI but 5 points in PA. I'm not sure I buy that they're really that different, or even that MI is necessarily the better state for Biden. But MI polling is often weird, and there hasn't been much high-quality PA polling lately. https://t.co/Waxnyug2r9 — PolitiTweet.org
