"The backlash against the left was a key part of the 1968 presidential race. Richard Nixon famously ran a campaign on 'law and order'..."

"One commercial featured scenes of protest, as Nixon argued that 'in a system of government that provides for peaceful change, there is no cause that justifies a resort to violence.' Alabama Gov. George Wallace was a lot more direct that year in his third-party bid. While racism was at the heart of his message, he also denounced student protesters as 'silver spoon brats' who advocated 'treason' and said of protesters, 'Some of ’em lie down in front of my automobile, it’ll be the last thing they’ll ever wanna lie down in front of.' The scenes of violence in Chicago outside the Democrats’ 1968 presidential convention, meanwhile, further contributed to the notion that left-wing lawlessness had gotten out of control. It was a nightmare event for Hubert Humphrey’s beleaguered presidential campaign, one where the public overwhelmingly sided with the Chicago police, not the demonstrators. (And, of course, guess where Democrats are holding their 2024 convention: Chicago.)... [I]n November of 1968, Nixon and Wallace combined for 57 percent of the vote...."
