my preferred excerpts:

the common good:

And ultimately, healing our country will come down to each of us, as citizens and individuals, doing the work—trying to reach across divides of race, class, and politics and see through the eyes of people very different from ourselves. When we think about politics and judge our leaders, we can’t just ask, “Am I better off than I was four years ago?” We have to ask, “Are we better off? Are we as a country better, stronger, and fairer?” Democracy works only when we accept that we’re all in this together.

and hyperpoliticization

 hyperpolarization now extends beyond politics into nearly every part of our culture. One recent study found that in 1960, just 5 percent of Republicans and 4 percent of Democrats said they’d be displeased if their son or daughter married a member of the other political party. In 2010, 49 percent of Republicans and 33 percent of Democrats said they’d be upset by that. The strength of partisan identity—and animosity—helps explain why so many Republicans continue to back a president so manifestly unfit for office and antithetical to many of the values and policies they once held dear. When you start seeing politics as a zero-sum game and view members of the other party as traitors, criminals, or otherwise illegitimate, then the normal give-and-take of politics turns into a blood sport.

and the racially divisive troll:

Trump undermines the national unity that makes democracy possible.

Democracies are rowdy by nature. We debate freely and disagree forcefully. It’s part of what distinguishes us from authoritarian societies, where dissent is forbidden. But we’re held together by deep “bonds of affection,” as Abraham Lincoln said, and by the shared belief that out of our fractious melting pot comes a unified whole that’s stronger than the sum of our parts.

At least, that’s how it’s supposed to work. Trump doesn’t even try to pretend he’s a president for all Americans. It’s hard to ignore the racial subtext of virtually everything Trump says. Often, it’s not even subtext.
