When Oklahomans go to the polls August 25, every registered voter — Republican, Democrat, independent or Libertarian — will find State Question 846 on the ballot. The measure would add a new section to Article 3 of the Oklahoma Constitution requiring proof of identity for every method of voting, in any election conducted by a county election board or the State Election Board. It would also direct the Legislature to spell out in state law what counts as acceptable proof.

Showing ID at an Oklahoma polling place is not new. The state has required it since 2011, when a voter-approved statutory requirement took effect. Under current law, a voter presents either a government-issued photo ID or the free voter identification card the county election board mails to every registrant. A voter carrying neither can still cast a provisional ballot by signing an affidavit listing name, address, date of birth and either a driver's license number or the last four digits of a Social Security number.

So what would actually change? On day one, very little. The amendment takes a requirement that already exists in statute and moves it into the constitution. The difference is durability: a statute can be rewritten by any future Legislature, while a constitutional provision can be undone only by another statewide vote of the people. Republican lawmakers, who sent the question to the ballot through Senate Joint Resolution 47 during the 2026 session, cited exactly that scenario — a future Legislature repealing the ID law — as the reason to act now.

Opponents read the same text and see a transfer of power rather than a safeguard. Because the amendment orders the Legislature to define proof of identity for any method of voting, the Oklahoma Policy Institute and other critics argue it gives lawmakers firmer constitutional footing to tighten rules around absentee and mail voting, and that a future Legislature could set requirements strict enough to squeeze some eligible voters out. They also point out that Oklahoma's elections have not produced evidence of the impersonation fraud ID rules guard against — meaning the amendment adds durability, not security.

The question passes with a simple majority of those who vote on it, and it lands on a runoff ballot, where turnout is typically a fraction of a November electorate. The marquee contests August 25 are Republican runoffs, including the governor's race, which will shape who shows up. Whatever the margin, the result is binding: if SQ 846 passes, voter ID becomes constitutional law that only another state question can touch; if it fails, the 2011 statute stays on the books exactly as it is.
