So in my recap from San Francisco earlier this summer, this bit from Julian Castro at the DNC this week is part of what I was talking about:
What the president did in allowing the children of undocumented immigrants to become citizens was Marco Rubio’s idea, but only Julian Castro got to brag about it at a convention. Only Castro got to make the incontrovertible point that, “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 one generation. But each generation passes on to the next generation the fruits of their labors…. My mother fought for civil rights so that instead of a mop, I could hold this microphone.”
Emphasis added.
