She's certainly had some slip ups in projecting roles.
I recognize that the following is a rationale which is to say my opinion/perception...an attempt to make sense of the bits and pieces I know of her life and my ability/desire to make those sensible within my understanding of human behavior.
With that caveat, I'm of the opinion that she moves between channeling a handful of public personas/schema that are worn somewhat like clothing/uniforms and which keep the 'real Hillary' from public view and are associated with the 'task' she's working on.
One is a Gloria Steinem-like personality pushing to liberate women from second class roles, and the other is Maggie Thatcher-like pushing for individual and national gravitas and toughness. She tends to overplay both. In between, when she's attempting to connect as a 'real person' and bond with the people. This is often characterized by a 'me, too' type commentary on the most obvious public sentiments around the news stream as seen by personalities on 'The View'.
Am I getting this correctly? Maybe not. But we are told by various sources that the public HRC and the private HRC are different. And, many people do these things, which gives it a place on the table for consideration.
I don't mean to say HRC is flawed or unusual because she approaches life this way. We all know people who do this, we could be some of that 'many' who also do this.
