Robert Byrd was a widely known and long serving democrat senator. He was also a former KKK member who freely used the "N" word in public. Since most KKK members in the 20th century were card carrying democrats, why wasn't any democrat ever questioned about his KKK support? The good old double standard?
Byrd also disavowed his klan membership in the late 40s and took a pro integration stand as a Senator
His record of voting was endorsed by the NAACP
Not many of todays Republicans can say the same thing
