Doctor Duke is an American political activist. The Wiki's write up is very hostile, eagerly telling us that he is a liar, thief and fornicator. It alleges that 'Duke says' or 'Duke claims'. It does not say he is wrong. That would be the lie direct, which contravenes their policy of pretending to take it down the middle. You might like to compare their story with that of the Metapedia. Doctor Duke wrote Jewish Supremacism: My Awakening on the Jewish Question, which got some very good reviews on Amazon.com. It sold well in Russia, which has cause to remember Jews without love. You can get it free as a download from Archive.org. If you can fault it on fact, sources, references, or entirely reasonable inferences do let me know; I am open to comment.
UPDATE 2016 David Duke Is Running For The U.S. Senate In Louisiana. He is recommended by Kevin MacDonald and hated by the Main Stream Media, just like Donald Trump, two big points in his favour.

The Main Stream Media hate him more than Donald Trump. That alone is reason to vote for him.
