Aharon Wasserman was frustrated by the sheaves of papers he received every night.
As deputy field director in the Georgia office of Barack Obama's 2008 presidential campaign, the Cumberland County, N.J., native's job was to collate daily canvassing reports, crunching data on issues such as who got registered and who was likely to vote.
One evening, the 21-year-old Rutgers University junior, who had taken a leave to join the campaign, grabbed another young staff member, Justin Lewis, "who wasn't so good at knocking on doors, but was pretty good at programming," Wasserman recalled recently.
Together they spent 20-hour days devising a social-media tool - a "game-changer," the nonpartisan New Organizing Institute has called it - that maximized efforts by the campaign's field offices and led to the prodigious get-out-the-vote initiative that proved key to Obama's success.
