As someone familiar with government bureaucracy, both personally and from a historical perspective, I don’t think Project 2025 is all that feasible, at least in the short/medium term.
These government bureaucracies are massive. There is no way you can hire some wine mom from Palm Beach be an environmental scientist at the EPA just because she loves Trump. Government jobs usually require things like interview panels to score people. These jobs have minimum requirements, etc that you can’t actually just bypass. And there so many layers of management. Sure, Trump can staff these agencies with his people at the very top, but that’s something GOP presidents have always done (and Democrats put industry-friendly people in there anyway).
But more importantly, these bureaucracies have their own “immune systems” that prevent attempts to subvert their power. Put it this way: let’s say we got a commie elected to president. The first thing we would want to do is “project 2025” the CIA, right? Just imagine how hard that would actually be, and how effective the CIA would be in largely thwarting this attempt.
I also like to point out how afraid libs were when Trump was threatening to nuke the DPRK and possibly start WW3. Not a single lib thought to say “maybe we should strip the power away from a president to be able to do this sort of thing”. But libs would rather die in a nuclear winter than consider fundamentally altering power relationships in government.
