There you go again. Duke is a Republican. Take a look:
http://www.duke.org/biography.html Became the National Director of the Knights of the Ku Klux Klan in 1974. Although his organization was completely legal and nonviolent (no members were ever charged with any crimes against minorities) the press and public could not differentiate between his group and completely separate "Klan" organizations. Other so-called "Klans" conformed to a Hollywood-generated image of ignorance, hate and violence. So in 1978 he resigned and formed the NAAWP, a White civil rights organization.
After his election to the House of Representatives in Louisiana, due to time constraints, he passed on his leadership of the NAAWP. Since that time the NAAWP has undergone a series of leadership changes and internal struggles. He is not associated or involved in any way with any current NAAWP groups.
He publishes the Duke Report, an international newsletter of uncensored conservative commentary that defends the rights and heritage of people of European descent. Subscribers can now be found in every American state and every nation of the world where Europeans reside in significant numbers.
David Duke was elected in 1989 and served as a member of the House of Representatives and was a full participating member of the Republican Legislative Delegation. He served on Committees: Health and Welfare, and Judiciary.
Authored landmark conservative legislation, including House Bill 1013 (1990), the first antiaffirmative action challenge passed by a legislative body in America.
He was recently elected to Chairmanship of the Republican Parish Executive Committee of the largest Republican parish (county) in Louisiana. (St. Tammany RPEC, At-Large Representative, term 1996-2000)
There you go again. Duke is a Republican I think I'll take my info from other places than duke.org, if you don't mind.
Apart from that: do you have any data that shows Duke as currently holding any Republican post? That would be a bit interesting, since he has spent a substantial amount of time during the last years as a fugitive in Russia.
On the other side, we have good and solid data showing klanners holding posts with the democrats (Byrd), and good and solid data showing Nazi kingpins running for positions in the Libertarian party. One of them was, if I remember, the übernut Martin Lindstedt.
