Vacancies

See also: How vacancies are filled in state legislatures

If there is a vacancy in the Oklahoma State Legislature, the governor must call a special election no later than 30 days after the vacancy occurs. No special election can be called if the vacancy occurs in an even-numbered year and if the term of office will expire in that year. This second provision allows special elections to be held for outgoing senators with two or more years left in their terms.[2]

If a senator announces his or her resignation before March 1 but the effective date lies between the general election and the new session, a special election can be held on the general election dates. The winner of this election will take office upon the senator's official resignation. This only applies to senators with two or more years remaining in their terms.[2]

Redistricting

In Oklahoma, both congressional and state legislative district boundaries are drawn by the Oklahoma State Legislature. These lines may be vetoed by the governor.[7]

If the legislature is unable to approve a state legislative redistricting plan, a backup commission must draw the lines. The commission comprises the following seven members:[7]

  1. The governor appoints one Republican and one Democrat.
  2. The majority leader of the Oklahoma State Senate appoints one Republican and one Democrat.
  3. The majority leader of the Oklahoma House of Representatives appoints one Republican and one Democrat.
  4. The lieutenant governor serves as the non-voting chair of the commission.

The Oklahoma Constitution requires that state Senate district boundaries take into account "population, compactness, area, political units, historical precedents, economic and political interests, contiguous territory, and other major factors."[7]

The redistricting committee of the state House adopted redistricting guidelines similar to the senatorial district requirements described above. These guidelines apply to state House and congressional districts, as well. These guidelines may be amended by the state legislature at its discretion.[7]

Gov. Kevin Stitt (R) signed new legislative maps into law on November 22, 2021.[8] The Senate approved the Senate map in a 46-1 vote on November 17, 2021, and the House approved the Senate map 95-1 on November 19, 2021.[9] The House approved the House map 88-3 on November 17, 2021, and the Senate approved the House map 44-2 on November 19, 2021.[10]These maps took effect for Oklahoma's 2022 legislative elections.
