The problem I see with this is that the 1960s were not evenly distributed. America may be different I guess but my parents studied in London at the time and talked about what a shock it was too see the values and fashions of what we think of as the 60s now. I wonder how many people, especially in small towns and very religious communities, would actually become more socially conservative"Hell, if you wanted to go back in time, you could have an earlier AIDS/HIV epidemic happen right during the tail end of the Summer of Love. In that world, young people are overloading the healthcare system in a panic instead of the old, so you'd see a mass of young people organizing for universal healthcare (during the heyday of late-20th-century activism) fighting against older folks who are saying "I told you so" with their ballots. That could create an interesting scenario where political polarization is at an equal magnitude to OTL's present, but it's broken across generational lines with boomers of all people being shifted to the left permanently."
