The right thinks the federal bureaucracy is dominated by leftists; that’s why it’s a “deep state.” Does that make sense?
The key concept here is self-selection. It is highly likely, for example, that environmentalists are overrepresented in the EPA; why would someone with strong feelings about property rights want to work there? But what about the FBI, which is, of course, led by a Trump nominee? Does anyone seriously believe that rabid leftists are attracted to law enforcement as a career? Is that even slightly plausible?
Take the DOJ as another example. Lawyers are, by and large, a conservative group; they are affluent enough to have something to lose, and they practice in a field that revolves around precedent. The attorneys at the DOJ are required to follow and enforce the written rules, regardless of their personal predispositions about politics. There is no reason to believe they don’t.
Most of the jobs in the bureaucracy are occupied by powerless timeservers who don’t care one way or the other if the government is run by the right or the left. A few stray agencies have mission with ties to a particular ideology, as with the EPA and the FBI. Taken together, they don’t amount to anything like a “deep state” dominated by the left.
What the reactionaries actually object to is not a politically-driven “deep state,” but one that is predictable and bound by rules and clearly identified procedures. Trump doesn’t think he should be subject to any rules. That’s why part of his agenda is to eliminate guardrails and subject government completely to his personal whims.
