Dixiecrat can't shake his racist roots, and slowheadedly makes his way to the white guy party.
Someone forgot to tell Mister Miller that the Republican Party absorbed the racially motivated Dixiecrats years ago. Some people are just slow, I guess. The Democrats are now the party for racial justice and harmony, unlike some Democrats of his day...who, unlike Lincoln, were the defenders of segregation and other social diseases of the Old South, which he may be pining to return.
But maybe not. Maybe he is just a slowheaded simpleton among similars...
