Like most Americans, Vinson Cunningham first became aware of Barack Obama in 2004, when he gave a breakout speech at the Democratic National Convention. “Very good posture, that guy,” Cunningham noted. “We hang our faith on objects, on people, based on the signs that they put out,” Cunningham tells David Remnick. “And that’s certainly been a factor in my own life. The rapid and urgent search for patterns.” Although Cunningham aspired to be a writer, he got swept up in this historic campaign, working on Obama’s longshot 2008 run for the Presidency, and later worked in his White House. Cunningham’s adventures on the trail inspire his first novel, “Great Expectations,” an autobiographical coming-of-age story about where and how we seek inspiration.  Cunningham recalls that Obama was seen as the “fulfillment” of so many hopes and dreams for people like himself. Now he wishes the former President were playing a larger role. “I will admit that it has been dispiriting,” in Obama’s post-Presidential life, “to see him making movies and being on Jet Skis as the world burns. … more like a movie star than someone whose great hope is to change the world.”
