America has become increasingly polarized when it comes to trust. Voters who distrust the system — who see institutions as corrupt and are prone to conspiracy theories — have long existed on the far left and far right. But Donald Trump seems to have sparked a realignment, what the writer Matthew Yglesias calls “the crank realignment.” The G.O.P. is now the political home of the distrustful, and Robert F. Kennedy Jr.’s Trump endorsement was a clear sign of these changing times.

In 2020, Pete Buttigieg wrote a book on trust in politics. And he’s been persistent in making the case — in speeches, on TV — for what he calls “a better kind of politics.” So I wanted to talk to him about his theory of politics. Why does he think so many Americans have lost trust in the government? What responsibility does the Democratic Party have here? And how does he believe trust can be restored?

Note: I invited Buttigieg on the show in his personal capacity so we could discuss his thoughts on the election without violating the Hatch Act, which prohibits members of the government from campaigning in their official guise. This also means I wasn't able to ask Buttigieg many questions about his work as transportation secretary. But I think we still had a pretty fascinating conversation.
