Purges like the democrats do all the time when they take power?
I would suggest that you don’t really need a “purge” anyway.
Take the partisans out of the top positions of these agencies, and make it a priority for new leadership to start doing competency testing for all the rank and file. Include searching for complaints about political activism while on the job.
Not a purge. A proper vetted culling.
It has the added benefit of giving you time to replace the bad apples as you sift them out.
I believe it’s NY that can’t fire teachers for any reason.. They must keep them on the payroll and send them to a location where they just sit with the other miscreants until they reach retirement.. How sick is that....
