There are few historical guides. It is hard to think of a precedent for a president who endorses violence against political foes, sees the Justice Department as his own personal prosecutor, calls the press “the enemy of the people,” tears children from parents, brags of multiple sexual assaults, threatens to lock up his opponents, enthuses about war crimes, “falls in love” with the foulest dictator on the planet, refuses to divest of personal holdings in office, lambastes allies, treats the Treasury as a casino, actively endorses the poisoning of the environment, destabilizes NATO, baits minorities, lies incessantly, and oversees a resurgence of the white nationalist right. Any single gesture in any one of these areas would have been political death for most previous presidents
