The Nebraska GOP scored another sweep in statewide offices.
In addition to governor and U.S. Senate, Republicans won the races for attorney general, secretary of state, treasurer and auditor.
Bob Evnen topped Democrat Spencer Danner in the race to succeed Secretary of State John Gale, who is retiring, and incumbent State Auditor Charlie Janssen defeated Democratic challenger Jane Skinner.
Attorney General Doug Peterson ran unopposed, as did John Murante, who will replace term-limited fellow Republican Don Stenberg as state treasurer.
