Ethan Roeder, the director of Obama for America's data operation, has penned a New York Times op-ed pushing back on reports that suggest the president's campaign knows too much about you. "Reading what others muse about my profession is the opposite of my middle-school experience: people with only superficial information about me make a bunch of assumptions to fill in what's missing and decide that I'm an all-knowing super-genius.," Roeder writes.
