I have looked up the ground conductivity for your area, its not great, its not that much different from my area.
First of all - some stock car radios, particularly from the 60's and 70's, had GREAT AM sections. Combine them with the 60 inch whips that cars and trucks used to have, and you had a great DX setup. Equal to or better than the GE.
Secondly - it is possible you got a defective GE Superadio. It happens - mass production for Radio Shack being what it is. Try the GE on other things - like WBAP 820, KTRH 740, KLIF 570. These ought to be easy catches for a GE in your location. If you aren't getting them, and the rest of the band is so-so (weak reception on "locals" like KLBJ 590 and WOAI 1200) - then return it. Go somewhere else and try another one. I haven't tried your particular reception area in several years, but there is no reason why a good GE won't work on your target station. You could check e-Bay for GE Superadio 2's - some users swear they are even better than the 3's. I haven't had that experience, but I am chasing a design problem on a 1 that might explain some variability in performance.
Thirdly - the station itself might not be living up to its theoretical transmission area:

If they don't keep up their ground radials, don't watch their pattern, etc., they could degrade to almost nothing. They do have to protect KOKC to the North - here in Dallas KOKC sounds almost like a local. A good indication of whether your station is doing well is if near sunset you hear KOKC underneath them. That would also be another check of the GE Superadio. If you hear a lot of KOKC, especially in the daytime, it could mean your station is very weak.
