Nebraska Revised Statutes Chapter 32. Elections § 32-816. Official ballots;  write-in space provided;  exceptions;  requirements

(1) A blank space shall be provided at the end of each office division on the ballot for registered voters to fill in the name of any person for whom they wish to vote and whose name is not printed upon the ballot, except that at the primary election there shall be no write-in space for delegates to the county political party convention or delegates to the national political party convention.  A square or oval shall be printed opposite each write-in space similar to the square or oval placed opposite other candidates and issues on the ballot.  The square or oval shall be marked to vote for a write-in candidate whose name appears in the write-in space provided.

(2) The Secretary of State shall approve write-in space for optical-scan ballots and any other voting system authorized for use under the Election Act.  Adequate provision shall be made for write-in votes sufficient to allow one write-in space for each office to be elected at any election except offices for which write-in votes are specifically prohibited.  The write-in ballot shall clearly identify the office for which such write-in vote is cast.  The write-in space shall be a part of the official ballot, may be on the envelope or a separate piece of paper from the printed portion of the ballot, and shall allow the voter adequate space to fill in the name of the candidate for whom he or she desires to cast his or her ballot.
