> Eh, wasn't one of the main reasons Clinton ran aground the belief that her nomination was due to a stitch-up inside the DNC (selection of Presidents ... nearly, at least)?

No,.that belief was a side effect of (1) the fact that it was, to a certain extent true that her nomination was largely a product of elite arrangements and structural advantage, and (2) the deep and broad unpopularity that was the actual reason she ran aground in what should have been the easiest election for Democrats in a long time.

Well, no. Laws are only created by Congress. Regulatory agencies can create non-trivial policies, and you might want to argue that the distinction between a regulatory policy and law is minimal or non-existent. But regulatory agencies are never what proponents of the deep state are discussing in my experience. Likewise with judges - and if we wanted to somehow include judges in the deep state, we have the problem that Trump has at this point appointed more federal judges in a single term than any other president and more SCOTUS judges than any other president. If judges are part of the deep state, Trump can not in any way be said to be fighting against it.
