Statement about Oklahoma's 2024 General Election from Paul Ziriax, Secretary of the State Election Board:

"Oklahoma's 2024 General Election is one for the history books. Unofficial results show that more Oklahomans cast a vote for President than any previous election. Voters set a new record for in-person early voting by more than 120,000. We also had the largest number of registered voters heading into this election since we began tracking this statistic in 2000.

"As Oklahoma's chief election official, I am proud of the Oklahomans who exercised their right to vote in this election. I am deeply grateful for the poll workers, county election officials, and State Election Board employees who worked so hard to make this election possible even with heavy turnout and despite the storms that ravaged parts of our state in the days before the election. Our election officials are thankful to local, state and federal law enforcement officials for their efforts to keep everyone safe during the General Election."
