The biggest issue for me is whether large numbers of Americans can begin to think that government can actually help make the country a fairer place. And that's partly a matter of policies that achieve results in terms of reducing inequality and raising middle-class and working-class incomes, which have been flat for decades. But it's also symbolic and rhetorical, it's whether Hillary Clinton can - or whoever's president - can persuade Americans that it's happening and that they can begin to trust their elected officials a little bit more and their institutions of government a little bit more.

There's a great book about that, "The Breaking Point" by Stephen Koch . It won't improve your opinion of [Ernest] Hemingway.

I do think Donald Trump would be a catastrophic turn in American history.

I've read a lot of war writing, even World War I writing, the British war poetry of Wilfred Owen and Siegfried Sassoon, Robert Graves's memoir "Goodbye to All That," and a civilian memoir "Testament of Youth" by Vera Brittain .

When Donald Trump says make America great again, we know whose America that is.

There's the basket of deplorables, who are bigots of various stripes, misogynists, anti-Muslim, racists, homophobes.

Since I was a kid. I had this series by Ballantine Books about the history of World Wars I and II. In my 20s, it was the Vietnam War literature of novelists like Tim O'Brien, Philip Caputo, and Tobias Wolff, and then nonfiction such as "A Bright Shining Lie" by Neil Sheehan and "The Best and Brightest" by David Halberstam . Those are the two best histories of Vietnam.
