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. "Sadly for me, this is a bunch of malarkey. You may chafe at how much the online world knows about you, but campaigns don’t know anything more about your online behavior than any retailer, news outlet or savvy blogger."
