Members of the Oklahoma Democratic Party are calling on the Democratic National Committee to invalidate the results of a June state party election to elect a new party chair.

Eight Oklahoma Democrats, including Christine Byrd, who lost the party chair election, sent a letter to the DNC on Monday requesting a new election to select a party leader.

Oklahoma Democratic Party chairwoman Alicia Andrews defeated Byrd by 12 votes in an election marred by a tabulation error.

The confusion started at the Democrats’ state convention on June 8 when the number of votes cast in the chair election was higher than the number of delegates in attendance combined with the number of proxy votes from people who couldn’t attend the convention.
