It wasn't that long ago that the "conscience" of the senate, was at one time not only a member of the klan...he was a grand kleagle....who was the "conscience" of the senate? None other than Robert Byrd (D)
And you don't have to look to far, or to hard to find plenty of other democrats who were also active in the klan:
Hugo Black - Supreme Court Justice (D)
Theodore G. Bilbo - US Senator (D)
Bibb Graves - Governor of Alabama (D)
Clifford Walker - Governor of Georgia (D)
George Gordon - US Congress (D)
One doesn't have to be a rocket surgeon to look at the history of the klan...the hot beds of klan activity, and then look at the politics of those locals to know which party has the long history of support and membership in the klan...
It is always interesting to see who attempts to rewrite history and who accepts it and tries to learn from it...look at who is trying to tear down civil war monuments now is if tearing them down would erase that period of our history...
