CBS seems to me to be playing it two ways here -- on one hand, they're sticking to a script used for ages, the "fish out of water" story. However, on the other hand, as they well know, I think CBS wants to get this message out to voters:
"Remember folks, we've got [GW and] a bunch of country bumpkins running our nation now!"
In short, some not-so subliminal political advertising from CBS, IMO...

This has already been done, and is called "The Anna Nicole Show" (Anna is from Texas, not Appalachia, but she's definately hillbilly material).
