OKLAHOMA COUNTY – Democrat Jennifer Mayo carved out a nail-bitingly narrow victory Tuesday night to flip the Oklahoma County Commissioner seat for District 3, defeating Republican Jessica Clayton by just 67 points, according to data from the State Election Board.
It was the highest-profile win on a night that saw Democrats sweep offices at the County-level, with Jessica Thompson defeating Republican Christie Miller for County Treasurer and John Gibbons unseating incumbent Republican Larry Stein for County Assessor, a role Stein has filled since 2019.
But Mayo’s ascendency could be the most consequential, tilting the balance of power on the Board of County Commissioners in favor of Democrats for the first time in decades.
“Tonight, Oklahoma County voters made it clear that they’re ready for a new chapter in county leadership,” Mayo said in a Facebook post just after midnight, “and I’m incredibly honored to be part of what comes next.”
Mayo has a long history of nonprofit and outreach work, currently working for Hunger Free Oklahoma and having previously worked the Regional Food Bank of Oklahoma and Untied Way of Central Oklahoma.
She joins District 1 Commissioner Jason Lowe, a Democrat, and District 2 Commissioner Brian Maughan, now the lone Republican, who serves as chairman of the board.
District 3
Oklahoma County’s 3rd District is comprised mostly of Edmond and far northern parts of Oklahoma City, as well as Luther and Arcadia, and it has remained firmly Republican on the Board of County Commissioners for years.
The district is currently represented by Interim Commissioner Paul Foster, who assumed the role following the resignation of Republican Miles Davidson following a highly publicized sexual misconduct scandal.
Neck-and-neck race with Clayton
Mayo’s race against Republican opponent Jessica Clayton proved to be among the tightest statewide Tuesday.
Clayton is a longtime Oklahoma County staff member, serving as Maughan’s chief deputy before assuming the newly designated role of County Manager, overseeing County finances and bureaucratic duties.
Mayo took a clear early lead just after polls closed, but Clayton eventually closed the gap, claiming a narrow lead of her own with over 90% of county precincts reporting.
But by the time all of the precinct counts were in, Mayo claimed the race by just 67 votes.
Oklahoma has no rule in place for automatic recounts, but the tally was close enough that Clayton may have grounds to request one.
That scenario is unlikely, however, as Clayton congratulated Mayo on “her victory” in a social media post late Tuesday night, appearing to officially concede the race.
Pro-transparency, anti-jail tax
The long-troubled planning, development, and funding of the new Oklahoma County Detention Center proved to be the primary driving campaign issue for Mayo, who was vocally opposed to Tuesday’s proposition of imposing a new sales tax to fund the project.
That proposition lost by a decisive margin, with over 62% of voters rejecting the measure.
Mayo ran on a staunchly pro-transparency platform, promising to support a full independent audit of jail finances, to push for clearer oversight of County development plans, and to “publish clear, regular updates on costs, jail performance, and outcomes,” according to her campaign site.
“Oklahoma County has significant challenges ahead, and addressing them will require cross-sector collaboration, a willingness to make difficult decisions, and the courage to question decisions that don’t make sense,” her post-victory Facebook statement reads. “We have an opportunity to strengthen public safety, improve accountability, and restore the trust of residents. I intend to bring the same determination, curiosity, and willingness to ask difficult questions that I brought to this campaign.”
