Why this Democrat is running a race she knows she can't win

CBC quotes Shawn Donahue in an article about a Democrat running a Senate race in North Carolina to draw attention to Republican gerrymandering. Gerrymandering has long been an issue in U.S. elections. When the party in power is drawing the map, Donahue says it's a recipe for trouble. "The thing I always ask my class is, like, if you and your buddies know that you are going to always completely control some group or board or thing that you're in, why would you ever voluntarily give up that power?" he said.
