Nah, too many have been acting like Biden and Harris have been in the right to spite anyone to the left of them. The reason it matters coming from Sanders is because he is a good faith actor. A lot of people lost any moral standing on the issue to a degree that frankly shocked me. I genuinely think that something broke in some people who are online too much (and being on this board is being online too much) that made people go into unnatural political corners. Too many lost the ability to tell the difference between a progressive (me and majority of black and brown people under 45 across a variety of professions) and leftists (who are obstinate and are the type to vote for Stein or Nader). Sanders has always been a progressive and so are his supporters and it’s why the Green Party, DSA and others don’t like him. His stance has always been the progressive stance - you guys just enjoy arguing with people who won’t be moved.
Tru Mac told y’all years ago that to people as left as him - someone like me, Sanders or Warren are considered moderates.
