What striking to me, however certainly expected, is all the sycophantic drivel heaped onto a powerful person. "You looked fabulous", "we were discussing how incredible you are". Perhaps aides think somehow they are being supportive, but if I were that powerful person, I believe I would rather just a few people I trust to tell me when I'm effing up - than everyone telling me how fantastic I am.
And if you were powerful, and wanted to, you would likely be able to find ways to surround yourself with such people. But I think often enough, the people who want power don't want it because they're very well-centered, and I think it's fair to assume that politicians and other people mostly select the nature (which can mean what those really think and/or what they claim they think) of their "underlings" by the signals they send, the incentives they give, by whom they hire or fire. In other words, the dog is probably wagging the tail, not the other way around.
I could be wrong, I don't know this woman and don't follow US politics that closely, but just from random things like this https://www.youtube.com/watch?v=-dY77j6uBHI I would call it a somewhat educated guess. Some people don't want to know the truth about themselves, that's the exact opposite of their mission in life. By which I don't mean to bash Clinton in particular, the list of big time politicians I wouldn't suspect this about would be very short and hard to come up with.
