Our national polling average has tightened a bit to Biden +7.6. We haven't had that many super high quality polls lately though. Also a bit less clear whether state polls imply much tightening. Still, we aren't seeing as many of those double-digit leads. https://t.co/cy51vc5isJ https://t.co/mmREWWCmfV — PolitiTweet.org
