Republican
Mark Tedford is an American politician and insurance agent who is the Oklahoma House of Representatives member from the 69th district.
Open seat -- the current officeholder is a Republican, Kevin Hern, who is not running (running for U.S. Senate).
Why we think this
- This district's baseline partisan lean favors Republicans by about 10 points of margin before anything else is considered.
- This is an open seat: the current officeholder (a Republican, Kevin Hern) is not on the ballot, which tends to make the race more competitive than a defended seat.
