The American people want to make sure that the rules of the game are fair. And what that means is that if you look at surveys around Americans' attitudes on trade, the majority of the American people still support trade. But they're concerned about whether or not trade is fair, and whether we get the same access to other countries' markets that they have with us. Is there just a race to the bottom when it comes to wages, and so forth.

I am looking forward to getting out of the bubble. I am glad that I'm leaving this place at a relatively young age, at 55. So I have the opportunity for a second maybe even a third act in a way that I think would be tougher if I were, you know, the age of some presidents when they left.

If we're going to prevent large parts of this Earth from becoming not only inhospitable but uninhabitable in our lifetimes, we're going to have to keep some fossil fuels in the ground rather than burn them and release more dangerous pollution into the sky.

In America, there's a failure to appreciate Europe's leading role in the world.

Ultimately, peace is just not about politics. It's about attitudes; about a sense of empathy; about breaking down the divisions that we create for ourselves in our own minds and our own hearts that don't exist in any objective reality, but that we carry with us generation after generation. And I know, because America, we, too, have had to work hard over the decades, slowly, gradually, sometimes painfully, in fits and starts, to keep perfecting our union.

We have states. And we have cities. And we have counties. And we have the private sector. And - and so the country still works even when Washington's dysfunctional.

It [the Constitution] didn't break free from the essential constraints that were placed by the founding fathers in the Constitution, at least as it's been interpreted, and the Warren court interpreted it in the same way that generally the Constitution is a charter of negative liberties. It says what the states can't do to you, it says what the federal government can't do to you, but it doesn't say what the federal government or the state government must do on your behalf. And that hasn't shifted.
