I won't comment on Senators Warren and Harris as they are both doing just fine and will do even better as the field continues to whittle down. I agree with everything you say about Yang. Most of this can (not attacking, not being attacked, positive team-player, etc.) be applied to Mayor Pete as well. Mayor Pete has way more name-recognition and more of an upside to him than Mr. "John" Yang. I will directly only address the last two sentences (highlighted). You are assuming that the "Presidential Candidate Debates" even remotely resemble debates. That is a dangerous assumption.
