Here's my latest running average of demographic splits in national live-interview polls w/ new NYT/Siena added in. Biden's surged w/ 65+ between Sept. and Oct., but just a big a deal is the steady decline in undecided/third party since June/July (and vs. '16, of course). https://t.co/TZDBta582B — PolitiTweet.org
