State Election Board Secretary Paul Ziriax announced on Dec. 10, 2025, that no political party filed a notice to allow Independents to vote in its primaries and runoff primaries during the 2026-27 election years.

Since no political party provided a notification to the State Election Board Secretary by the statutory deadline, all primaries will remain closed for the 2026-27 election years. Oklahoma has three recognized political parties: Democratic, Libertarian, and Republican.

Oklahoma is a modified closed primary state. In order to participate in a party’s primary or runoff primary, you must be a registered voter of that party; however, there is an exception.

In every odd-numbered year between Nov. 1 and 30, state law allows all recognized political parties in Oklahoma the opportunity to open their primaries and runoff primaries to Independents during the next two election years by notifying the Secretary of the State Election Board.

If a party chooses to open its primaries, the deadline is extended to Dec. 15 for the other recognized parties to respond or change their response. If no notice is provided, a party’s primary remains closed under state law.

Voters who would like to change their party affiliation should do so before April 1, 2026. State law prohibits party affiliation changes April 1 – August 31 of evennumbered years.

Party affiliation changes submitted during the closed period will be processed on Sept. 1, 2026.
