On a workaday morning outside the College Hill Library on Tampa's Dr. Martin Luther King Jr. Boulevard, an old man's knees begin to buckle.

He is standing outside along with dozens of others, most of them black, some who lined up even before the library-turned-early-voting-site opened its doors.

As the man starts to crumple, people rush out of line to help. Get a chair, they are saying, and give him air, and somebody call an ambulance.
