In another sign of Donald J. Trump’s grip on the Republican Party, his team wants the party’s platform to be a succinct pro-Trump document, not an “unnecessarily verbose treatise.”
Project 2025 may be the unofficial platform, although officially adopting it may be a step too far for even the Republican party. If only because of the optics of it, not because they don't agree with all of it.
Certainly Trump has suggested cleaning house of "liberal" members of the public service so he can install his own cronies that will let him do whatever he wants, which is in line with Project 2025.
