Young new residents have transformed many D.C. neighborhoods over the past decade, but for the most part D.C. politics remain much the same. The Post’s Robert Samuels explores this paradox, noting that one in three D.C. Democrats is between ages 18 and 34, with about 51,000 having registered in the past four years alone. “Their massive numbers could swing the mayoral election — if someone could just figure out how to get them to vote,” Samuels writes. “The very group whose large economic footprint has jolted the city to life is barely felt in city politics.” The reasons why are on display at the Coupe in Columbia Heights — full of young, well-educated D.C. residents passionate about plenty, except for the city they live in. “Even when we start talking about [D.C.] politics, no one really knows what they are talking about, so the conversations end quickly,’’ said Jason Lopez, who has spent one of his 30 years in the District.
