Okla. Stat. tit. 34 § 22
Whenever any measure or proposition is submitted to a vote by the initiative or referendum, it shall be the duty of the precinct election board of the precinct to make and transmit to the county election board the returns thereof in the same manner that they make their returns in the case of an election of public officers, transmitting to such county election board a certificate of the total number of electors voting in such elections; and the county election board shall keep a record showing such total number of votes cast in each of such precincts as shown by such returns. Should the proposition be one covering the state at large, or any district therein, or be of such other nature as to require it the county election board shall certify the result of such election to the State Election Board in the same manner as it certifies the result of election for public officers, and such county election board shall transmit to the State Election Board a certificate showing the total number of votes cast at any such election. It shall be the duty of the State Election Board to keep a record of all such election returns made to it under the provisions of this section.
