As the Harris correspondent tonight, I think my topline takeaway is that she's playing in the big leagues now and she has the attacks to show for it. She got flack for her prosecutorial record, but had a sustained and detailed exchange on health care with Biden at the start of the debate. Some of my colleagues think that was too in the weeds -- and it might have been -- but I do think it's a big deal that she was right on center stage physically and metaphorically tonight with Biden.
