DeSantis is a scary character. All the cruelty, narcissism, bigotry and authoritarian tendencies of Trump, but with an actual 3-digit IQ and basic grownup self-control.
Time will tell whether his humourless, charm-free persona resonates with the lowbrow MAGA hordes who crave entertainment.
Either way, as Umair points out, both he and Trump are in some ways simply a product of the forces characterizing this end stage of our civilization. If they fall, other corrupt demagogues will take their place.
How do decent people prevail against these forces? I wish I had a good answer.
