I suspect the parent is referring to a distressing trend of mean reversion: we’re really running the motor on all cylinders to elect people to high office based on what family they hail from, a phenomenon that dates at least as far back as 2000 (and there were the Kennedy family, and before that…).

It has precedent for about 10 thousand years before that, but we were moving in the right direction on it and we’ve reversed course.

Yeah, I also suspect(ed) it's something like that. But then it's pretty weird of Dr Chemicals-as-food to single out Mrs Clinton like he did. The Bushes are a much more blatant example.
