I've always been underestimated. It's happened throughout my entire career.

Economic growth is the key to everything. But once you have economic growth, it is important that we reach out to people who live in the shadows, the people who don't seem to ever think that they get a fair deal. And that includes people in our minority community; that includes people who feel as though they don't have a chance to move up.

Furthermore, when there is cheating, the cheating needs to be called. And I see that the administration has become much more aggressive on that front [of retraining people who get displaced].

The role of money in politics is terrible, particularly when you're running for president. You get a handful of billionaires who can basically buy the White House.

I think people are frustrated with dysfunction, not just dysfunction in government, but a lot of dysfunction that surrounds them. I get the frustration with drugs in the neighborhood or my kids with big college loans can't find a job.

We've just let too many things happen. And now, try to turn around and fix it. Getting involved in a [Syria] civil war directly was never something I thought made sense.

You cannot build a little guy up by tearing a big guy down. Abraham Lincoln said it...
