We can lose so much of what we've gained in terms of the kind of democratic freedoms and market-based economies and prosperity that we've come to take for granted.

One of my strengths is I have a pretty even temperament. I don't get too high when it's high and I don't get too low when it's low. And what I found during the course of the presidency, and I suppose this is true in life, is that investments and work that you make back here sometimes take a little longer than the 24-hour news cycle to bear fruit.

The second thing we have to do is to make sure that all of us think about how we approach our elections and our democracy not only to secure them from vote tampering, but also to make sure that we understand when propaganda is being churned through the system.

One of the challenges over the last decade is America has done experiments in nation building in places like Iraq and Afghanistan and we've neglected, for example, developing our own economy, our own energy sectors, our own education system. And it's very hard for us to project leadership around the world when we're not doing what we need to do.

I do think that saving the economy was a pretty big deal. We did a lot of stuff early that ended up having an impact. I believe that the work we've done in moving our energy future in a cleaner direction is going to stick even if some of the individual steps that we took are reversed by future administrations. I think that it's embedded itself in the economy.

I am sorry that they are finding themselves in this situation based on assurances they got from me.

Members of Congress on both sides of the aisle, are motivated by all kinds of issues. They're sincerely interested in the economy, in terrorism, in social issues. But the one overriding thing they're interested in is getting reelected. And if they think that it's harder for them to get reelected by cooperating with each other, then they won't cooperate.
