Almost the entire modern history of the US government (including his last term) showed that not much at all changes. And it definitely doesn’t change quickly. Even stuff like tax rates have barely had any meaningful change considering US tax revenue has only increased exponentially since the 1980s along with the GDP. On paper very little changes in gov when you look more than skin deep.

This might be a new precedent where politicians actually do what they say and work hard to change the government but I’m highly skeptical.

Sounds like a lot of noisy broad stroke announcements and highly reactive social media headlines that will turn out to be minor IRL outcomes or get smacked down in court.
