On March 9, the Oklahoma Senate unanimously passed SB 375. It moves the date of the non-presidential primary from the last Tuesday in June to the third Tuesday in June. Assuming it becomes law, it would also automatically move the declaration of candidacy deadline for non-presidential independent candidates a week earlier. In Oklahoma, non-presidential independent candidates don’t need a petition; they just file a declaration of candidacy and a filing fee.
SB 375 does not change the petition deadline for newly-qualifying parties, which would continue to be March 1.
