Biden is at 27.5% in an average of early state polls (weighted by the number of Dems in each state). That's almost identical to his 28.6% in national polls over the same period. Warren & Sanders are actually underperforming their national polls *more* than Biden in early states. https://t.co/dxKtSUkj0f — PolitiTweet.org
