I especially cannot imagine anyone who grew up during the Cold War era listening to Donald Trump and saying, you know what, that's a guy that I want to support. It makes zero sense.

We've seen tremendous progress in many ways under President [Barack] Obama. I mean, if we think about where the economy was when he got in - you know, we were losing more than 700,000 jobs a month. The unemployment rate was skyrocketing. And now it's at under 5 percent, so there is a lot of progress that has happened.

In my mind, there's no question that Donald Trump has energized the Latino community more than any other presidential candidate. Unfortunately for him, he's done that in a negative way.

Donald Trump is just unfit, unprepared, just doesn't get it, shouldn't be the commander in chief of America.

As my family story shows, Latinos have been a blessing for USA for many generations. The future of America depends in part on the success of the Latino community, and this opportunity is just one more signifier of that.

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.

The American dream is not a sprint, or even a marathon, but a relay. Our families don't always cross the finish line in the span of one generation. But each generation passes on to the next the fruits of their labor. My grandmother never owned a house. She cleaned other people's houses so she could afford to rent her own. But she saw her daughter become the first in her family to graduate from college. And my mother fought hard for civil rights so that instead of a mop, I could hold this microphone.
