And does not explain all the young men voting for him.
They didn’t vote differently. There were a larger number of the greatest generation that were more comfortable with shared sacrifice in service of society and less entitled like the baby boomers are.
there's no "same people"; leaded gasoline was phased out in the 80's but wasn't finished until around 2000s.
The elderly are simply more engaged and that's what happened.
It doesn't happen overnight. It takes time to weaken a strong country to the point where a reality show buffoon can become president.
Yes, the psychological effects of environmental lead last a lifetime. No, they didn’t vote differently, they have always gravitated to actors that promise simple solutions and highlight bad blood and animus.
