I certainly don’t believe that all 63 million trump voters are stupid, but perhaps this quote from a movie will illustrate things a bit.
“For although psychopaths are a small minority, it seems significant that whenever organized and militant hate exist a psychopath is the leader, and if, for instance, one hundred disgruntled and frustrated individuals fall in line behind one psychopath then, in essence, we are concerned with the actions of one hundred and one psychopaths. Sidney Potier-Pressure Point-1962”
Substitute stupid for psychopath and you start to get the picture. Although it does work either way.
