Within 90 days of the closing of the polls for each regular state general election, and for each presidential primary election, the supervisors of the checklist in the towns, and the corresponding officers in the cities, shall send one of the marked checklists which were used in that election, certified by the officers, to the state archives. In addition, if directed by the secretary of state, they shall send one of the unmarked checklists which were used in the state general election at which a president was elected to the clerk of the federal district court for the district of New Hampshire. One marked copy of every checklist used in any election shall be turned over to the town or city clerk by the supervisors. The clerk shall preserve such checklists in his or her custody for a public record for a period set forth in N.H. Rev. Stat. § 33-A:3-a.
