Many political commenters I have listened to on various media claim not to be too worried about a Trump win because they are convinced he won't win and that most of his followers will fade away. Many, like myself, feel that even the Republican party has finished itself off like so many who put their trust in him because they had no idea what the character of a narcissistic sociopath is really like.
From Britanica:
Faustian bargain, a pact whereby a person trades something of supreme
moral or spiritual importance, such as personal values or the
soul, for some worldly or material benefit, such as knowledge, power, or riches. The term refers to the
legend of
Faust (or Faustus, or Doctor Faustus), a character in German
folklore and
literature, who agrees to surrender his soul to an evil spirit (in some treatments,
Mephistopheles, or Mephisto, a representative of
Satan) after a certain period of time in exchange for otherwise unattainable knowledge and magical powers that give him access to all the world’s pleasures. A Faustian bargain is made with a power that the bargainer recognizes as evil or amoral. Faustian bargains are by their nature tragic or self-defeating for the person who makes them, because what is
surrendered is ultimately far more valuable than what is obtained, whether or not the bargainer appreciates that fact.
