Hard Hats and Blue Cities: David Paul Kuhn on the Roots of the Working Class Revolt

The modern Democratic Party has a class and culture problem. Blue city leaders struggle to understand their cultural and political disconnect with working-class voters. Why did so many, both within and beyond blue cities, cast their ballots for Donald Trump, who gives tax breaks to the wealthy? When and how did the Democratic Party lose the allegiance of the white (and increasingly of the black and brown) working class?

In this episode, former politics reporter and author David Paul Kuhn joins us to unpack a pivotal, yet often overlooked, event: New York City's "Hard Hat Riot," a spontaneous May 1970 attack by hundreds of blue collar construction workers, in lower Manhattan building the World Trade Center towers, on long-haired anti-war protesters four days after the shootings at Kent State University.

Kuhn, whose richly textured book and fascinating new PBS documentary delve into the riot and its cultural and political import, discusses with us the crack up of the Democratic Party’s New Deal coalition as a chasm grew between traditionally patriotic blue-collar workers and countercultural, college educated anti-Vietnam War "elites" amidst the economic shifts of the late 1960s and early 1970s.

Kuhn argues the riot serves as a microcosm for an emerging – and enduring – political and social polarization in American politics. He argues that the "hard hats," frequently mischaracterized as pro-war, were in reality anti-anti-war, feeling their patriotism and sacrifices were being disrespected by protestors who were waving Viet Cong flags and burning the Stars and Stripes. The conversation explores how white ethnic working class Americans felt increasingly alienated from blue city leaders and the New Left counterculture, and how first Richard Nixon and then subsequent Republican politicians weaponized that rift for their own political advantage.  

Drawing contemporary parallels, the episode explores how the events of 1970 New York City triggered the Republican Party's rapid inroads with non-college educated working-class Americans. The discussion examines the lasting impact of deindustrialization, cultural tensions, and the ongoing challenge for the Democratic Party to re-engage with this critical demographic, offering a historical lens through which to understand the persistent polarization affecting blue cities.
