If I were a Berniecrat I'd rather have Ellison in the House than as fundraisier/hack-in-chief. What if he's replaced on Congress by a Blue Dog? How does that help the movement at all?
Best case he's replaced by another Berniecrat, but the new one will be inexperienced and less effective for a while.
Who gives a sh*t, nothing good is gonna come out of Congress any time soon, and 1/435th is an irrelevancy.
More relevant than a fundraiser who supports ALL democratic nominees no matter what. If the Vermont Democratic Parry decided to nominate against Bernie in 2018, Chairman Ellison will be required to endorse the guy.
