“We all understand that freedom isn't free. What Romney and Ryan don't understand…” — Julian Castro

I do think we need to hold countries accountable who violate trade agreements that are already in place. We need to get stronger about enforcement, that in the future if we strike a trade agreement, toughening up labor standards and environmental standards and enforcement standards is something we absolutely need to do.

I focus on telling the truth and painting a vision of what the country can become in the future if we make the right investments together in things like health care, and education, and jobs and opportunity.

I couldn't help but to think back to my classmates at Thomas Jefferson High School in San Antonio. They had the same talent, the same brains, the same dreams as the folks we sat with at Stanford and Harvard. I realized the difference wasn't one of intelligence or drive. The difference was opportunity.

But one of the most enjoyable things for me is that running for office gives you this license to enter the world of somebody else and to hear about the dreams that they have for themselves, for their family, for the country.
