First off, a strong President (a Reagan, if we could be so lucky). Then, he would have to reorganize all the bureaucracies so they answer to him and his staff. Move people around to different places and different jobs so as to break up the liberal chummies working together to advance the liberal doctrine and inhibit any conservative tendencies. Fire anyone who doesn't do their job as instructed (downsize everything, for a start).
IDK, though. I still believe it can be done, but, like anything as massive as our feral government, you have to start somewhere and the best place to do that is from the inside.
Yes if we got someone who was dedicated enough and didn’t care about four more years. I’m not holding my breath.
