If Trump isn't making lists of Deep State operatives as we speak, to enact the largest purge of people and structures ever seen the very same day he is sworn in, he will become a confirmed historical failure. That's his only value as a politician, his potential to become the one who dismantled the most evil structures of power in the world.
He failed to embrace his historical task in his first term, for whatever reasons: partly, because he is an outsider to most of those structures, but not a complete 100% outsider either, because you can't become the POTUS if you are. In other words, he also had masters to serve. Probably not the same as the Uniparty candidates, and not so powerful, but he did and does. So he tried to live in the grey area, with the current result.
If he once again tries that after this, he will definitely have been an utter failure, and that's how history will remember him forever.
