The Russian threat fear went away after the Kennedy assassination and Vietnam. Most boomers figured out that the US government wasn't any better than the Russian government.
Hippies went on to take over education and the government. The majority of boomers got on with their life.
Carter put the finishing touches on a boomer belief in a just government with his draft dodger amnesty.
Biggest error in trying to figure the boomers out, IMO, is equating boomers with hippies. All hippies were boomers, but not all boomers were hippies.
Trump tunes in to the visceral hate most boomers have for hippies quite well. Trump is the voice most boomers who were not hippies lost 50 years ago.
