From W to Trump, from Mayberry Machiavellis to Killer Bigot Clowns

One thing the usual "Republicans, stupid OR evil?" conundrum misses is the extent to which evil pushes away the majority of competent people who are also decent people. Quite apart from the scandal and the danger of handing executive powers in one of the richest most belligerent nations in history of the world over to people lacking a moral compass (do unto others as you would have others do onto you; from those to whom much is given much is expected; don't squander long-term flourishing for short-term satisfaction; don't let the perfect be the enemy of the good; be wary of the human capacity for rationalization and the human tendency to feel irrationally threatened by difference; etc.) are the endless practical problems caused when loyalty trumps competence, experience, temperament, qualifications in assigning responsibilities across the organizational archipelago of partisan, activist, and administrative roles leading to actually-real problems that would otherwise be avoided. At least, I think this true. Is this true? Does one eventually pay a price for making avoidable mistake after mistake after mistake? That really does cause incompetents to drop the ball, get bogged down in distractions, lose the narrative, lose party discipline and cohesion, hemorrhage support, get the short end of the stick in negotiations, all those worries that endlessly bedevil and preoccupy Democrats will apply to Republicans, too, it's not going to be IOKIYAAR on the stupid AND evil...?
