Our politics are increasingly divided on fundamental issues like the legitimacy of elections and the nature and integrity of the basic systems of American government. That’s the most important fact of this election. But strange new zones of agreement have been emerging, too — on China, outsourcing and health care. What should we make of that?

In his book “The Rise and Fall of the Neoliberal Order” the historian Gary Gerstle describes these shifts in consensus in terms of political orders — these eras that stretch for decades, when both parties come to accept a certain set of ideas. In this conversation he walks me through the political, economic and social factors that shaped two political orders in the last century: the New Deal order and the neoliberal order. And we apply this lens to what’s happening in our politics right now.

It may seem strange to take a step back in time right before the election. But I think Gerstle’s framework helps uncover an overlooked dimension of the 2024 race and where politics might go next.
