I think that district also covers some areas south and east of OKC. Also, my youngest son said that her opponent (his name escapes me right now) didn't start campaigning until about a week or two before the election. That might have been a factor as well.
That's what makes America Great. I like James Lankford. I may not always agree with his positions, but I admire any politician that has principles, and stands with them. Same applies for all us normal people.
