Never stop believing that fighting for what is right is worth it.

There is no question in my mind that if we summon our resources, both our leadership resources and all of the tools at our disposal, not just military force, which should be used as a last resort, but our diplomacy, our development aid, law enforcement, sharing of intelligence in a much more open and cooperative way. We can bring people together, but it cannot be an American fight.

We need a wide variety of ways for voters to get a good look at our candidates.

When I was growing up, my parents always told me that I had to do what I thought was right and not listen to other people. That was hard for me.

I take running for president and being president really seriously. It's a - maybe the toughest job in the world, right? And I knew that there was unfinished business from the successful two terms of President Obama, whom I had served, but that we needed to go further on the economy, on health care, and so much else.
