Roy Acuff, a far better man than McGraw (and much more revered) ran for Govenor of TN in 1948 as a Republican. He lost. This was when TN was a Yellow Dog dem state.
Now, TN is a (marginal) red state. Mississippi is even redder. Does Mr McGraw think his star power is enough to overcome this, even knowing the lessons of Mr. Acuff's history?
It's still yellow dogs as far as the eye can see here in Nashville.
