The Constitution is very clear that Congress, not the President or Executive Branch, controls the power of the purse. All Congressional Republicans need to do is stand up to Trump and insist on reclaiming a power that shouldn't have been ceded to Trump and Musk to start with. And yet we all know that practically none of these Congressional Republicans are going to do shit publicly - they're all terrified of Dear Leader, Musk, and their own voters. So they have no one to blame but themselves, although they'll never admit it. Instead they'll continue to beg for scraps from Trump 2.0 and then try spin whatever they get as them working hard to save their districts and states from the deep cuts that are coming.
And in less-prosperous red states like WV or Mississippi or Alabama or Louisiana or Arkansas it's likely going to be especially devastating, because such a high percentage of people in those states depend on federal programs to get by. For example, wait until rural hospitals and other medical facilities start to close due to lack of federal funding and elderly rural Trumpers are driving 30, 40, or 50 or more miles to the closest hospital.
