Hillary had to take back her comments about Nancy Reagan (and Ron) being rather good about AIDS in the 80's. We can't let the Received Narrative get away from us, now can we? Our entire political framework is dependent on believing in the bad motives of our opponents after all. Take that away and there is often nothing left. Not always, but often.
This is where Hillary is not the candidate that Bill was. Bill knows what the narrative is supposed to be and adheres to it. In fact, he is good enough that he is able to take occasional liberties with it, bending it and remaking it to his needs, in ways that few can. She was there, and she still doesn't know. Hell, even I know what standard wisdom is on Reagan and AIDS, and I was paying no particular attention to politics at the time. I was, however, employed at the psychiatric and dealing with some of the first few cases in the state and attending the trainings that contradicted each other from one year to the next. So I got to see what all the trial narratives were before we settled on one.
I got to hear medical professionals claim we have always been at war with Eastasia, too. I don't expect Hillary got to hear much of that - nor should she have been expected to - but if you are going to be a politician, you have to pick this stuff up and remember it.
