Sanders is built up to be the best of a bad lot; but he is so stereotypically an American senator, it leads to disappointment in those who had hopes. This is a natural reaction.

And while he has said things that are not bad, there is such a huge gap between him and what is needed, that he, the career politician does not have a chance to be esteemed by many on the left. And his words, which would be amazing to hear other politicians say, are judged harsher than the statements put out by them.
