[Kartographer]

I don't know if the shoe fits:

Lonesome Rhodes: Rednecks, crackers, hillbillies, hausfraus, shut-ins, pea-pickers - everybody that's got to jump when somebody else blows the whistle. They don't know it yet, but they're all gonna be 'Fighters for Fuller'. They're mine! I own 'em! They think like I do. Only they're even more stupid than I am, so I gotta think for 'em.

The author is hung up on donnie not being a hillbilly but the examination of the character played by AG could have been played by anyone from any station in life. Him being a country hick just made the situation more crazy for the movie to have the most impact.
