The other thing to keep in mind is that realigment helps all of the candidates who are comfortably above 15% to boost their margins. If Sanders or Biden initially get say 23% of the vote, they could wind up with ~27% or something after second choices join them. https://t.co/F0Gq3cIBFY — PolitiTweet.org
