It did happen under Bush but the dems were in place at
justice. He never cleared them out the way Clinton did.
The entrenched bureaucracy are all Dems working
against any Republican in office. That is how Valerie Plame
and Joe Wilson were able to carry out their vicious plot
at CIA.
That is not how the civil service works. The President appoints (and removes) the US Attorneys. He does not appoint the entire civil service, nor does he appoint all of the assistant US attorneys. People like Brenda Morris and William Welch are civil servants, not appointees. Bush couldn’t just fire them. But a skillful Attorney General can manage the department in a way so as to put people like that in positions where they can do little or no harm. That is what Holder has done with the ones that aren’t singing the Obama tune. Plame and Wilson are civil servants, as well. Not easily removed, but very easily moved and sidelined. Bush is not a vicious, Chicago-style politician and so left many people in place where they could damage him.
