Potential problems with your theory are that old people voting percentage isn’t way higher than young people and that people tend to get more conservative as they age.
The boomers were the ones out protesting the Vietnam War and fighting for civil rights. Now they are the establishment and behaving the same as those who they protested in their youth.
Hopefully, the batshit craziness will die down, but there will be new conservatives to replace the ones who die off.
