RealClearPolitics did have WV, TN, MO, LA and AR listed as swing states. It was only 8 years earlier, in 1996 that Bill Clinton swept all of them. Although I do remember thinking back then that if Southern Democrat Al Gore lost all of them in 2000, how could a Yankee from New England win them over in 2004?
Not to mention that among these five states there were six Democratic senators (woulda been seven if Carnahan had not been killed) and a couple of Democratic governors. I'd imagine Democrats had the registration advantage in three or four if not all five?
