House Bill No. 2425, introduced by Hilbert, amends various sections of the Oklahoma election laws to establish new dates and procedures for primary and runoff elections. The bill specifies that primary elections for federal, state, and county officers will now be held on the first Tuesday in March of each even-numbered year, while runoff primary elections will take place on the third Tuesday of June in the same year. Additionally, it allows for elections to be held on the first Tuesday of March in any even-numbered year and the fourth Tuesday of August in any odd-numbered year. The bill also prohibits changes in political affiliation from December 1 of an odd-numbered year until June 30 of the following even-numbered year.

Furthermore, the bill modifies the candidate filing process by requiring declarations of candidacy to be filed starting the first Monday in December of odd-numbered years, with a supplemental filing period for newly formed political parties. It clarifies the timeline for filing contests and the issuance of Certificates of Election, allowing unopposed candidates to receive their certificates shortly after the filing period closes. The changes outlined in this bill are set to take effect on January 1, 2027.
