An old post of mine:
"CULTURAL BACKLASH: Would the counterculture have produced a socially conservative backlash even without the flag burning and the rhetorical (and at times actual) violence of the antiwar movement? Perlstein's *Nixonland* suggests that the rising crime and cultural upheaval at Berkeley and other California campuses was a huge asset to Ronald Reagan's campaign for governor in 1966; and the first major disruptions at Berkeley, in late 1964, occurred *before* the Vietnam escalation, and had nothing to do with the war at all. It's reasonable to assume that long hair, drug use, open sexuality, and other signs of the cultural apocalypse would have led to a strong reaction from those embracing more traditional social values..."--Jeff Greenfield, *If Kennedy Lived.* (I have quite a few quarrels with that book, but I think it is plausible enough on this point.)
