Trump is not rock bottom. He's without question the stupidest person ever to step foot in the White House. But he doesn't care about government. He doesn't even care to dismantle it, outside of his quest to fire every person who thought Obama was a good president.
Read "The Fifth Risk". In it, you can see that Trump was totally unprepared to transition our government. Every agency waited in vain to try and help their new leaders continue to run the country. Eventually, some of those top positions were filled, and a few by pretty much the worst person you could pick; a person with the express intent to destroy that agency (like Scott Pruitt). But not all. Trump is destroying our government primarily through two means: neglect, because he has no desire nor ability to govern. And through ego, as he tramples every "check and balance" that isn't expressly written into law, searching for a personal "win". He has appointed people who approach him, wanting to either gut or profit from a government position.
Any semi-competent anti-government GOP nut could do the same thing, but far worse, with express intent rather than bumbling ineptitude and infantile entitlement.
