Okla. Stat. tit. 26, § 26-14-143: Ballot timeliness

An application for a military-overseas ballot is timely if

received by the last day for other voters in this state to apply for

an absentee ballot for that election. An application for a

military-overseas ballot for a primary election, whether or not

timely, is effective as an application for a military-overseas

ballot for the general election. An application for a military-

overseas ballot is effective for a runoff election necessary to

conclude the election for which the application was submitted.
