By coincidence or perhaps fate, the gray, nondescript building in Arlington, Virginia, where Patricia Solis Doyle runs Senator Hillary Clinton’s presidential campaign was a district office of Citizenship and Immigration Services until 2004. It’s a fitting space for Patti, 42, the daughter of Mexican immigrants and the first Latina to run a U.S. presidential campaign.

Her corner office is furnished with Clinton hand-me-downs, including an old kitchen table and daughter Chelsea’s armoire. But one thing stands out: a Diego Rivera painting, Los Sembradores. It shows two Mexican men toiling in the soil, bringing forth new life—the perfect metaphor for Patti’s current task.
