A slew of candidates who lost high-profile Senate races last year are asking voters to give them another shot with the midterm elections around the corner.

Democrat Sherrod Brown, the former Ohio senator, became the latest politician to announce a comeback bid Monday after losing in a presidential election year that buoyed his GOP rival. Before him, it was Dan Osborn, the independent populist who gave Sen. Deb Fischer (R-NE) a run for her money in Nebraska, and days earlier, former Democratic Rep. Colin Allred, who drew outsize attention and gobs of cash to his failed race in Texas.
