I disagree. Sanders is a bad fit for suburbanites period and i think that has more to do with him then progressivism in general.
I would agree with this and I say this as a college educated suburban voter who happened to vote for Sanders in 2016. In some cases it has more to do with how the message is coming across rather than the message itself. If her campaign didn't lose steam, Warren I think would have done quite well with these suburban voters. FWIW, Feingold I think would have done very well with the same suburban college educated never Trumper voter that Sanders struggled with.
