You cannot give up on the American dream. We cannot allow our fears and our disappointments to lead us into silence and into inaction.

We have a violence problem in America. And no one is having a debate about the violence problem. And I think this is a missed opportunity to have an honest and open conversation in this country about why these horrifying things are happening, not simply what they're using to carry this out, but why are people doing this to begin with?

I honestly believe that once people begin to understand what's at stake here, that we have a chance here not just to make our country great, but greater than it's ever been, and we have a plan to do it, I think is going to begin to influence a lot of voters, not to mention coalesce those maybe who were with someone else first around us.

I think future generations will look back at this history of our country and call us barbarians for murdering millions of babies who we never gave a chance to live.

I don't buy into the dystopian scenarios of self-aware robots enslaving mankind, but you don't have to be a sci-fi conspiracy theorist to acknowledge that plenty of good, well-paying jobs are being taken over by machines.

I do think the most important thing we need in leadership in our country, not just in the presidency but in the United States Senate, are people that have a clear vision of what the role of government should be in our lives and what the role of America should be in the world.

It's not in our nature. Americans have never been a people that drive through a nice neighborhood and say, 'Oh, I hate the people who live in these nice houses.'
