His breakdown should have been more granular....
Gen y & z right and left comparison, those groups represent the younger adults, the potential active populations.
Odds are that conservative cohorts are more disciplined, focused, already armed with skill levels, as well as having jobs, and thus skin in the game.
Contrast that with the special interest fractured leftists with so many dependent on gov money and services, unfocused, lacking self discipline and skill sets. Granted that antifa/blm/black bloc are currently using effective strategies and tactics, but how numerous are they likely to become?
Those are the critcal numeric comparisons.
Effective because antifa/BLM mayors allow them to be effective.
