Former U.S. Rep. Colleen Hanabusa won the democratic nomination for Hawaii's 1st Congressional district, which was left vacant by the late Rep. Mark Takai. "It feels bittersweet," Hanabusa said of winning the primary election. "You can't ignore the fact that it's not under the circumstances that you really would like because there is the passing of Mark. But it is nice to be in the position where it looks like we'll be heading back."
