I think your assessment of the three groups of voters is pretty good. I might add some average IQ variances as well.....
It really is too bad that most voters don’t read FR or anything else for a full discussion of the candidates.
This is the reason we have the current POTUS - force-fed fantasy from the candidate and propaganda puffery by the press and pundits.
It has always taken a kick in the head crisis to awaken Americans to reality and revival. (WWI & WWII & the Depression, Cold War etc.,) We regularly go soft and stupid - just because we can.
It must be nice to be so smart.
