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.

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

For my daughter, it's going to mean something special that Hillary Clinton accepts the nomination, and I wanted to make sure that she sees that.

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.

In the end, 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.

Tim Kaine is an excellent choice for vice president.

With the opportunity we build today for a shared prosperity tomorrow, America will prevail. It begins with re-electing Barack Obama.
