it's her personality. She's big on details (which is good), and love digging in to the weeds. See her campaign announcement rally in Iowa.

The irksome stuff doesn't feel sexist to me either. The way she handled the 'pocahantes' attacks was totally and utterly cringe worthy from start to finish. I imagine it would play out pretty similarly if Bernie, Biden or HRC had claimed native american heritage and gotten exposed (the thought of any of those three pretending to be native american is pretty funny to me though).

No doubt she'll face real sexism during the run, but the 'math teacher' and 'irksome' attacks aren't it in my mind.
