Warren also comes across as "coastal elite" (worked at Harvard and lived in eastern MA), something that I don't think applies to Bernie. I don't know how much feminism appeals to Bernie voters as well, and it would probably be a polarizing issue (lower-income Berniecrats vs latte liberal Berniecrats).
For people actually caring about some sort of
"coastal elite status," I doubt the difference between Vermont and Massachusetts's geographical locations will matter much. Vermont fits the mold just the same even if not in the literal sense, although I might add that it is just as close to the ocean as someone from eastern Oregon/Washington/California.
In the end, if she has the right kind of appeal
(which I personally think she does), the specifics of her professional career won't really matter anyway. Just like Trump being a New York City billionaire literally living in a gilded tower didn't matter to the legions of working class whites that supported him. If they believe the candidate has their back, they will look past all sorts of things.
