This isn't true, IMO. Sanders gaining ground in Iowa would *not* be in Warren's "immediate interest". It would make it harder for *her* to win the nomination, even if he also gained ground on Biden. They're competing for an overlapping pool of voters. https://t.co/VB9qc4n1kB https://t.co/hxIpGFrFw3 — PolitiTweet.org
