How the fuck is this country even still standing at this point with this chicanery and buffoonery at the reigns?

Basically because various parts of the government were pitted against each other, by design. Various organizations and levels of government have their own objectives, interests and resources and operate with varying amounts of independence and interdependence. It’s frankly messy and creates some inefficiency, but it’s sort of like biodiversity - a problem that impacts part of the government doesn’t impact all of it in the same way or at the same time, so it doesn’t completely collapse or grind to a halt.
