I will agree I didn't repeat (for the twentieth or thirtieth time or whatever) the premise of the OP which was federal employees using their jobs to undermine President and/or his policies/agenda. So I'll give you that one.
I have never been a federal employee, but have a few in my family and among my friends/acquaintances who have been and are and they tell me it happens, most especially in the first Trump administration. Some condone that. Some don't.
And yes Trump is unique since he is the first person in our lifetimes who was not a professional politician elected to be President. And because he wasn't tied to the status quo and thought and acted out of their prescribed box--he wasn't one of their own--he was hated by a much more militarized and radicalized left than what was apparent even under Obama. And, he was bitterly resented by old guard Republicans when he showed them up as the timid, feckless people they had been by doing what they said couldn't be done.
And Trump is the first President to have organized government lawfare put into action to take him down. About 70% of federal employees are on the record as Democrat donors. Probably most of the rest are also registered Democrats which has become an important requisite to get a job in government in DC.
So with a likely mostly hostile workforce in the DC federal government, the deep state is far more likely to have a lot of useful people at their disposal to undermine the LEGITIMATE authority of the President and his policies/agenda.
I don't think that is okay. And those who engage in that should be fired.
Do you agree?
