Miller was the last of the kind of democrats that used to control the “Solid South” when that meant solidly democratic. All the others have died out, many of them switched to the Republican party long ago with Strom Thurmond being one of the first. In those days the GOP was considered the “libeal” party.
I presume you mean "liberal." That would of course be historically correct. The Party of Lincoln was the first to not only accept blacks (former slaves) as members, they also seated former slaves into the U.S. Congress in the post Civil War era. Democrats (former slave owners) often left the chamber when such a representative was present. Let's not forget the good ol' boys in the RAT party and their connection to the creation of the KKK. This is history that never seems to get repeated in these days of revisionist teachings. This is the true threat of Common Core style programs. Like how the first serious gun control efforts since the American Revolution were aimed (pardon the pun) directly at former slaves in the southern states under the state level black codes and Jim Crow laws of the era. None of these laws was considered to be unconstitutional for over 100 years because the Amendments were solely applicable to the federal government and not the states under the doctrine of incorporation.
So, you're saying that William McKinley and Calvin Coolidge were liberals?
Are you saying that anything other than the Calhounian "compact" theory is liberal?
