Oklahoma: State makes election administration changes | NewsOK.com
The troubled April 3 special election in Tulsa’s House District 71 has led state and local officials to change procedures, software and training to makes sure all voters and candidates have confidence the process. On election night, Democrat Dan Arthrell was declared the unofficial winner by three votes. But a subsequent recount led to Republican Katie Henke being certified the winner by one vote. Only hours after the recount ended, Tulsa County election officials discovered two unsecured ballots for Arthrell still sitting in an election machine. They later said that evidence suggested that on two other occasions people were allowed to vote twice because of mistakes by precinct officials. Ultimately, the Oklahoma Supreme Court found it impossible to determine who won the election and invalidated the vote.
