Okla. Stat. tit. 19, § 19-84: Two-thirds vote required to relocate - Second election

If two-thirds of all the votes cast in the county at such

special election shall be in favor of any city, town or place, other

than the county seat, then such city, town or place shall thereafter

be the county seat; but if more than two towns or places are voted

for, and no town receives the requisite proportion of all the votes

cast, then all names of towns or places voted for on said ballot

except the two receiving the greatest number of votes shall be

dropped; and the Governor shall, in like time and manner, cause to

be called and held a second election at which only two towns or

places shall be voted for, and if any city, town or place other than

the county seat shall receive the requisite proportion of the votes

cast at the second election, such city, town or place shall

thereafter be the county seat; otherwise the county seat shall

remain unchanged.
