The longest serving Senator in history (and the man in second place for longest total time serving in Congress between both houses) was a Democrat but merely an exalted cyclops in the KKK (if I understand the organizational structure right, grand wizard is like a national president while exalted cyclops is more like a chapter president?). He also filibustered the Civil Rights Act. Again, Democrat - spent much of the late 70s to late 80s as either Majority Leader or Minority Leader as appropriate. Biden gave him a eulogy.

So is the lesson here that Republicans pick higher ranking KKK members for leadership positions than Democrats will?
