 Oklahoma is a closed primary state. Only registered voters of a political party may vote to select their party's nominees. If no candidate receives at least 50% of the vote in the primary, a runoff will be held between the top two vote-getters. If a candidate is unopposed in the primary or general election, that office does not appear on the ballot. Oklahoma does not permit write-ins.  |
