Oklahomans who want to change their party affiliation before the primary or run-off primary election later this year, must do so no later than Saturday, March 31, according to Dixie F. Smith, Secretary of the Delaware County Election Board.

Changes of political affiliation are prohibited by law during the period beginning April 1 and continuing through Aug. 31 in even-numbered years.

Each political party can nominate one candidate per office for the November general election. If two or more candidates from the same party file for one office, the party nominee is selected at either the primary or run-off primary election.

Only voters registered in a political party can vote to select that party's nominees unless the party gives Independent voters permission to vote in its primaries.

The Democratic Party has given Independent voters permission to vote in their primaries and runoff primaries in 2018 and 2019.

Oklahoma has three recognized political parties in 2018: Democrat, Libertarian and Republican.

All registered voters, regardless of political affiliation, may vote for any candidate at the November General Election and for state or local questions at any election.

Applications to register to vote or to change political affiliation are available at the Delaware County Election Board office, 225 S 5th St, Jay OK; most post offices; public libraries; state offices providing public assistance; and at most political party, candidate campaign offices. Forms may also be obtained online at www.elections.ok.gov and www.okcounties.org.
